SSE2 is used by\ndefault, but NEON must be enabled explicitly; see docs.\n\nWith other JPEG optimizations included in this version, we see\n2x speedup on a JPEG on an x86 machine, and a 1.5x speedup\non a JPEG on an ARM machine, relative to previous versions of this\nlibrary. The same results will not obtain for all JPGs and for all\nx86/ARM machines. (Note that progressive JPEGs are significantly\nslower to decode than regular JPEGs.) This doesn't mean that this\nis the fastest JPEG decoder in the land; rather, it brings it\ncloser to parity with standard libraries. If you want the fastest\ndecode, look elsewhere. (See \"Philosophy\" section of docs below.)\n\nSee final bullet items below for more info on SIMD.\n\n- Added STBI_MALLOC, STBI_REALLOC, and STBI_FREE macros for replacing\nthe memory allocator. Unlike other STBI libraries, these macros don't\nsupport a context parameter, so if you need to pass a context into\nthe allocator, you'll have to store it in a global or a thread-local\nvariable.\n\n- Split existing STBI_NO_HDR flag into two flags, STBI_NO_HDR and\nSTBI_NO_LINEAR.\nSTBI_NO_HDR: suppress implementation of .hdr reader format\nSTBI_NO_LINEAR: suppress high-dynamic-range light-linear float API\n\n- You can suppress implementation of any of the decoders to reduce\nyour code footprint by #defining one or more of the following\nsymbols before creating the implementation.\n\nSTBI_NO_JPEG\nSTBI_NO_PNG\nSTBI_NO_BMP\nSTBI_NO_PSD\nSTBI_NO_TGA\nSTBI_NO_GIF\nSTBI_NO_HDR\nSTBI_NO_PIC\nSTBI_NO_PNM (.ppm and .pgm)\n\n- You can request *only* certain decoders and suppress all other ones\n(this will be more forward-compatible, as addition of new decoders\ndoesn't require you to disable them explicitly):\n\nSTBI_ONLY_JPEG\nSTBI_ONLY_PNG\nSTBI_ONLY_BMP\nSTBI_ONLY_PSD\nSTBI_ONLY_TGA\nSTBI_ONLY_GIF\nSTBI_ONLY_HDR\nSTBI_ONLY_PIC\nSTBI_ONLY_PNM (.ppm and .pgm)\n\nNote that you can define multiples of these, and you will get all\nof them (\"only x\" and \"only y\" is interpreted to mean \"only x&y\").\n\n- If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still\nwant the zlib decoder to be available, #define STBI_SUPPORT_ZLIB\n\n- Compilation of all SIMD code can be suppressed with\n#define STBI_NO_SIMD\nIt should not be necessary to disable SIMD unless you have issues\ncompiling (e.g. using an x86 compiler which doesn't support SSE\nintrinsics or that doesn't support the method used to detect\nSSE2 support at run-time), and even those can be reported as\nbugs so I can refine the built-in compile-time checking to be\nsmarter.\n\n- The old STBI_SIMD system which allowed installing a user-defined\nIDCT etc. has been removed. If you need this, don't upgrade. My\nassumption is that almost nobody was doing this, and those who\nwere will find the built-in SIMD more satisfactory anyway.\n\n- RGB values computed for JPEG images are slightly different from\nprevious versions of stb_image. (This is due to using less\ninteger precision in SIMD.) The C code has been adjusted so\nthat the same RGB values will be computed regardless of whether\nSIMD support is available, so your app should always produce\nconsistent results. But these results are slightly different from\nprevious versions. (Specifically, about 3% of available YCbCr values\nwill compute different RGB results from pre-1.49 versions by +-1;\nmost of the deviating values are one smaller in the G channel.)\n\n- If you must produce consistent results with previous versions of\nstb_image, #define STBI_JPEG_OLD and you will get the same results\nyou used to; however, you will not get the SIMD speedups for\nthe YCbCr-to-RGB conversion step (although you should still see\nsignificant JPEG speedup from the other changes).\n\nPlease note that STBI_JPEG_OLD is a temporary feature; it will be\nremoved in future versions of the library. It is only intended for\nnear-term back-compatibility use.\n\n\nLatest revision history:\n2.13 (2016-12-04) experimental 16-bit API, only for PNG so far; fixes\n2.12 (2016-04-02) fix typo in 2.11 PSD fix that caused crashes\n2.11 (2016-04-02) 16-bit PNGS; enable SSE2 in non-gcc x64\nRGB-format JPEG; remove white matting in PSD;\nallocate large structures on the stack;\ncorrect channel count for PNG & BMP\n2.10 (2016-01-22) avoid warning introduced in 2.09\n2.09 (2016-01-16) 16-bit TGA; comments in PNM files; STBI_REALLOC_SIZED\n2.08 (2015-09-13) fix to 2.07 cleanup, reading RGB PSD as RGBA\n2.07 (2015-09-13) partial animated GIF support\nlimited 16-bit PSD support\nminor bugs, code cleanup, and compiler warnings\n\nSee end of file for full revision history.\n\n\n============================ Contributors =========================\n\nImage formats Extensions, features\nSean Barrett (jpeg, png, bmp) Jetro Lauha (stbi_info)\nNicolas Schulz (hdr, psd) Martin \"SpartanJ\" Golini (stbi_info)\nJonathan Dummer (tga) James \"moose2000\" Brown (iPhone PNG)\nJean-Marc Lienher (gif) Ben \"Disch\" Wenger (io callbacks)\nTom Seddon (pic) Omar Cornut (1/2/4-bit PNG)\nThatcher Ulrich (psd) Nicolas Guillemot (vertical flip)\nKen Miller (pgm, ppm) Richard Mitton (16-bit PSD)\ngithub:urraka (animated gif) Junggon Kim (PNM comments)\nDaniel Gibson (16-bit TGA)\nsocks-the-fox (16-bit TGA)\nOptimizations & bugfixes\nFabian \"ryg\" Giesen\nArseny Kapoulkine\n\nBug & warning fixes\nMarc LeBlanc David Woo Guillaume George Martins Mozeiko\nChristpher Lloyd Martin Golini Jerry Jansson Joseph Thomson\nDave Moore Roy Eltham Hayaki Saito Phil Jordan\nWon Chun Luke Graham Johan Duparc Nathan Reed\nthe Horde3D community Thomas Ruf Ronny Chevalier Nick Verigakis\nJanez Zemva John Bartholomew Michal Cichon github:svdijk\nJonathan Blow Ken Hamada Tero Hanninen Baldur Karlsson\nLaurent Gomila Cort Stratton Sergio Gonzalez github:romigrou\nAruelien Pocheville Thibault Reuille Cass Everitt Matthew Gregan\nRyamond Barbiero Paul Du Bois Engin Manap github:snagar\nMichaelangel007@github Oriol Ferrer Mesia Dale Weiler github:Zelex\nPhilipp Wiesemann Josh Tobin github:rlyeh github:grim210@github\nBlazej Dariusz Roszkowski github:sammyhw\n\n\nLICENSE\n\nThis software is dual-licensed to the public domain and under the following\nlicense: you are granted a perpetual, irrevocable license to copy, modify,\npublish, and distribute this file as you see fit.\n\n*/\n\n#ifndef STBI_INCLUDE_STB_IMAGE_H\n#define STBI_INCLUDE_STB_IMAGE_H\n\n// DOCUMENTATION\n//\n// Limitations:\n// - no 16-bit-per-channel PNG\n// - no 12-bit-per-channel JPEG\n// - no JPEGs with arithmetic coding\n// - no 1-bit BMP\n// - GIF always returns *comp=4\n//\n// Basic usage (see HDR discussion below for HDR usage):\n// int x,y,n;\n// unsigned char *data = stbi_load(filename, &x, &y, &n, 0);\n// // ... process data if not NULL ...\n// // ... x = width, y = height, n = # 8-bit components per pixel ...\n// // ... replace '0' with '1'..'4' to force that many components per pixel\n// // ... but 'n' will always be the number that it would have been if you said 0\n// stbi_image_free(data)\n//\n// Standard parameters:\n// int *x -- outputs image width in pixels\n// int *y -- outputs image height in pixels\n// int *channels_in_file -- outputs # of image components in image file\n// int desired_channels -- if non-zero, # of image components requested in result\n//\n// The return value from an image loader is an 'unsigned char *' which points\n// to the pixel data, or NULL on an allocation failure or if the image is\n// corrupt or invalid.

Therefore, the NEON support is\n// toggled by a build flag: define STBI_NEON to get NEON loops.\n//\n// The output of the JPEG decoder is slightly different from versions where\n// SIMD support was introduced (that is, for versions before 1.49). The\n// difference is only +-1 in the 8-bit RGB channels, and only on a small\n// fraction of pixels. You can force the pre-1.49 behavior by defining\n// STBI_JPEG_OLD, but this will disable some of the SIMD decoding path\n// and hence cost some performance.\n//\n// If for some reason you do not want to use any of SIMD code, or if\n// you have issues compiling it, you can disable it entirely by\n// defining STBI_NO_SIMD.\n//\n// ===========================================================================\n//\n// HDR image support (disable by defining STBI_NO_HDR)\n//\n// stb_image now supports loading HDR images in general, and currently\n// the Radiance .HDR file format, although the support is provided\n// generically. You can still load any file through the existing interface;\n// if you attempt to load an HDR file, it will be automatically remapped to\n// LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;\n// both of these constants can be reconfigured through this interface:\n//\n// stbi_hdr_to_ldr_gamma(2.2f);\n// stbi_hdr_to_ldr_scale(1.0f);\n//\n// (note, do not use _inverse_ constants; stbi_image will invert them\n// appropriately).\n//\n// Additionally, there is a new, parallel interface for loading files as\n// (linear) floats to preserve the full dynamic range:\n//\n// float *data = stbi_loadf(filename, &x, &y, &n, 0);\n//\n// If you load LDR images through this interface, those images will\n// be promoted to floating point values, run through the inverse of\n// constants corresponding to the above:\n//\n// stbi_ldr_to_hdr_scale(1.0f);\n// stbi_ldr_to_hdr_gamma(2.2f);\n//\n// Finally, given a filename (or an open file or memory block--see header\n// file for details) containing image data, you can query for the \"most\n// appropriate\" interface to use (that is, whether the image is HDR or\n// not), using:\n//\n// stbi_is_hdr(char *filename);\n//\n// ===========================================================================\n//\n// iPhone PNG support:\n//\n// By default we convert iphone-formatted PNGs back to RGB, even though\n// they are internally encoded differently. You can disable this conversion\n// by by calling stbi_convert_iphone_png_to_rgb(0), in which case\n// you will always just get the native iphone \"format\" through (which\n// is BGR stored in RGB).\n//\n// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per\n// pixel to remove any premultiplied alpha *only* if the image file explicitly\n// says there's premultiplied data (currently only happens in iPhone images,\n// and only if iPhone convert-to-rgb processing is on).\n//\n\n\n#ifndef STBI_NO_STDIO\n#include \n#endif // STBI_NO_STDIO\n\n#define STBI_VERSION 1\n\nenum\n{\n STBI_default = 0, // only used for req_comp\n\n STBI_grey = 1,\n STBI_grey_alpha = 2,\n STBI_rgb = 3,\n STBI_rgb_alpha = 4\n};\n\ntypedef unsigned char stbi_uc;\ntypedef unsigned short stbi_us;\n\n#ifdef __cplusplus\nextern \"C\" {\n#endif\n\n#ifdef STB_IMAGE_STATIC\n#define STBIDEF static\n#else\n#define STBIDEF extern\n#endif\n\n //////////////////////////////////////////////////////////////////////////////\n //\n // PRIMARY API -

This is\n * a very useful and long desired include file which contains several\n * very precise definitions for integer scalar types that is\n * critically important for making portable several classes of\n * applications including cryptography, hashing, variable length\n * integer libraries and so on. But for most developers its likely\n * useful just for programming sanity.\n *\n * The problem is that some compiler vendors chose to ignore the C99\n * standard and some older compilers have no opportunity to be updated.\n * Because of this situation, simply including stdint.h in your code\n * makes it unportable.\n *\n * So that's what this file is all about. Its an attempt to build a\n * single universal include file that works on as many platforms as\n * possible to deliver what stdint.h is supposed to. Even compilers\n * that already come with stdint.h can use this file instead without\n * any loss of functionality. A few things that should be noted about\n * this file:\n *\n * 1) It is not guaranteed to be portable and/or present an identical\n * interface on all platforms. The extreme variability of the\n * ANSI C standard makes this an impossibility right from the\n * very get go. Its really only meant to be useful for the vast\n * majority of platforms that possess the capability of\n * implementing usefully and precisely defined, standard sized\n * integer scalars. Systems which are not intrinsically 2s\n * complement may produce invalid constants.\n *\n * 2) There is an unavoidable use of non-reserved symbols.\n *\n * 3) Other standard include files are invoked.\n *\n * 4) This file may come in conflict with future platforms that do\n * include stdint.h. The hope is that one or the other can be\n * used with no real difference.\n *\n * 5) In the current version, if your platform can't represent\n * int32_t, int16_t and int8_t, it just dumps out with a compiler\n * error.\n *\n * 6) 64 bit integers may or may not be defined. Test for their\n * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.\n * Note that this is different from the C99 specification which\n * requires the existence of 64 bit support in the compiler. If\n * this is not defined for your platform, yet it is capable of\n * dealing with 64 bits then it is because this file has not yet\n * been extended to cover all of your system's capabilities.\n *\n * 7) (u)intptr_t may or may not be defined. Test for its presence\n * with the test: #ifdef PTRDIFF_MAX. If this is not defined\n * for your platform, then it is because this file has not yet\n * been extended to cover all of your system's capabilities, not\n * because its optional.\n *\n * 8) The following might not been defined even if your platform is\n * capable of defining it:\n *\n * WCHAR_MIN\n * WCHAR_MAX\n * (u)int64_t\n * PTRDIFF_MIN\n * PTRDIFF_MAX\n * (u)intptr_t\n *\n * 9) The following have not been defined:\n *\n * WINT_MIN\n * WINT_MAX\n *\n * 10) The criteria for defining (u)int_least(*)_t isn't clear,\n * except for systems which don't have a type that precisely\n * defined 8, 16, or 32 bit types (which this include file does\n * not support anyways). Default definitions have been given.\n *\n * 11) The criteria for defining (u)int_fast(*)_t isn't something I\n * would trust to any particular compiler vendor or the ANSI C\n * committee. It is well known that \"compatible systems\" are\n * commonly created that have very different performance\n * characteristics from the systems they are compatible with,\n * especially those whose vendors make both the compiler and the\n * system. Default definitions have been given, but its strongly\n * recommended that users never use these definitions for any\n * reason (they do *NOT* deliver any serious guarantee of\n * improved performance -- not in this file, nor any vendor's\n * stdint.h).\n *\n * 12) The following macros:\n *\n * PRINTF_INTMAX_MODIFIER\n * PRINTF_INT64_MODIFIER\n * PRINTF_INT32_MODIFIER\n * PRINTF_INT16_MODIFIER\n * PRINTF_LEAST64_MODIFIER\n * PRINTF_LEAST32_MODIFIER\n * PRINTF_LEAST16_MODIFIER\n * PRINTF_INTPTR_MODIFIER\n *\n * are strings which have been defined as the modifiers required\n * for the \"d\", \"u\" and \"x\" printf formats to correctly output\n * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,\n * (u)least32_t, (u)least16_t and (u)intptr_t types respectively.\n * PRINTF_INTPTR_MODIFIER is not defined for some systems which\n * provide their own stdint.h. PRINTF_INT64_MODIFIER is not\n * defined if INT64_MAX is not defined. These are an extension\n * beyond what C99 specifies must be in stdint.h.\n *\n * In addition, the following macros are defined:\n *\n * PRINTF_INTMAX_HEX_WIDTH\n * PRINTF_INT64_HEX_WIDTH\n * PRINTF_INT32_HEX_WIDTH\n * PRINTF_INT16_HEX_WIDTH\n * PRINTF_INT8_HEX_WIDTH\n * PRINTF_INTMAX_DEC_WIDTH\n * PRINTF_INT64_DEC_WIDTH\n * PRINTF_INT32_DEC_WIDTH\n * PRINTF_INT16_DEC_WIDTH\n * PRINTF_UINT8_DEC_WIDTH\n * PRINTF_UINTMAX_DEC_WIDTH\n * PRINTF_UINT64_DEC_WIDTH\n * PRINTF_UINT32_DEC_WIDTH\n * PRINTF_UINT16_DEC_WIDTH\n * PRINTF_UINT8_DEC_WIDTH\n *\n * Which specifies the maximum number of characters required to\n * print the number of that type in either hexadecimal or decimal.\n * These are an extension beyond what C99 specifies must be in\n * stdint.h.\n *\n * Compilers tested (all with 0 warnings at their highest respective\n * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32\n * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio\n * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3\n *\n * This file should be considered a work in progress.

They inform client applications of properties of the\n * corresponding face.\n *\n * @values:\n * FT_FACE_FLAG_SCALABLE ::\n * The face contains outline glyphs. Note that a face can contain\n * bitmap strikes also, i.e., a face can have both this flag and\n * @FT_FACE_FLAG_FIXED_SIZES set.\n *\n * FT_FACE_FLAG_FIXED_SIZES ::\n * The face contains bitmap strikes. See also the `num_fixed_sizes`\n * and `available_sizes` fields of @FT_FaceRec.\n *\n * FT_FACE_FLAG_FIXED_WIDTH ::\n * The face contains fixed-width characters (like Courier, Lucida,\n * MonoType, etc.).\n *\n * FT_FACE_FLAG_SFNT ::\n * The face uses the SFNT storage scheme. For now, this means TrueType\n * and OpenType.\n *\n * FT_FACE_FLAG_HORIZONTAL ::\n * The face contains horizontal glyph metrics. This should be set for\n * all common formats.\n *\n * FT_FACE_FLAG_VERTICAL ::\n * The face contains vertical glyph metrics. This is only available in\n * some formats, not all of them.\n *\n * FT_FACE_FLAG_KERNING ::\n * The face contains kerning information. If set, the kerning distance\n * can be retrieved using the function @FT_Get_Kerning. Otherwise the\n * function always return the vector (0,0). Note that FreeType doesn't\n * handle kerning data from the SFNT 'GPOS' table (as present in many\n * OpenType fonts).\n *\n * FT_FACE_FLAG_FAST_GLYPHS ::\n * THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT.\n *\n * FT_FACE_FLAG_MULTIPLE_MASTERS ::\n * The face contains multiple masters and is capable of interpolating\n * between them. Supported formats are Adobe MM, TrueType GX, and\n * OpenType variation fonts.\n *\n * See section @multiple_masters for API details.\n *\n * FT_FACE_FLAG_GLYPH_NAMES ::\n * The face contains glyph names, which can be retrieved using\n * @FT_Get_Glyph_Name. Note that some TrueType fonts contain broken\n * glyph name tables. Use the function @FT_Has_PS_Glyph_Names when\n * needed.\n *\n * FT_FACE_FLAG_EXTERNAL_STREAM ::\n * Used internally by FreeType to indicate that a face's stream was\n * provided by the client application and should not be destroyed when\n * @FT_Done_Face is called. Don't read or test this flag.\n *\n * FT_FACE_FLAG_HINTER ::\n * The font driver has a hinting machine of its own. For example, with\n * TrueType fonts, it makes sense to use data from the SFNT 'gasp'\n * table only if the native TrueType hinting engine (with the bytecode\n * interpreter) is available and active.\n *\n * FT_FACE_FLAG_CID_KEYED ::\n * The face is CID-keyed. In that case, the face is not accessed by\n * glyph indices but by CID values. For subsetted CID-keyed fonts this\n * has the consequence that not all index values are a valid argument\n * to @FT_Load_Glyph. Only the CID values for which corresponding\n * glyphs in the subsetted font exist make `FT_Load_Glyph` return\n * successfully; in all other cases you get an\n * `FT_Err_Invalid_Argument` error.\n *\n * Note that CID-keyed fonts that are in an SFNT wrapper (this is, all\n * OpenType/CFF fonts) don't have this flag set since the glyphs are\n * accessed in the normal way (using contiguous indices); the\n * 'CID-ness' isn't visible to the application.\n *\n * FT_FACE_FLAG_TRICKY ::\n * The face is 'tricky', this is, it always needs the font format's\n * native hinting engine to get a reasonable result. A typical example\n * is the old Chinese font `mingli.ttf` (but not `mingliu.ttc`) that\n * uses TrueType bytecode instructions to move and scale all of its\n * subglyphs.\n *\n * It is not possible to auto-hint such fonts using\n * @FT_LOAD_FORCE_AUTOHINT; it will also ignore @FT_LOAD_NO_HINTING.\n * You have to set both @FT_LOAD_NO_HINTING and @FT_LOAD_NO_AUTOHINT to\n * really disable hinting; however, you probably never want this except\n * for demonstration purposes.\n *\n * Currently, there are about a dozen TrueType fonts in the list of\n * tricky fonts; they are hard-coded in file `ttobjs.c`.\n *\n * FT_FACE_FLAG_COLOR ::\n * [Since 2.5.1] The face has color glyph tables. See @FT_LOAD_COLOR\n * for more information.\n *\n * FT_FACE_FLAG_VARIATION ::\n * [Since 2.9] Set if the current face (or named instance) has been\n * altered with @FT_Set_MM_Design_Coordinates,\n * @FT_Set_Var_Design_Coordinates, or @FT_Set_Var_Blend_Coordinates.\n * This flag is unset by a call to @FT_Set_Named_Instance.\n */\n#define FT_FACE_FLAG_SCALABLE ( 1L << 0 )\n#define FT_FACE_FLAG_FIXED_SIZES ( 1L << 1 )\n#define FT_FACE_FLAG_FIXED_WIDTH ( 1L << 2 )\n#define FT_FACE_FLAG_SFNT ( 1L << 3 )\n#define FT_FACE_FLAG_HORIZONTAL ( 1L << 4 )\n#define FT_FACE_FLAG_VERTICAL ( 1L << 5 )\n#define FT_FACE_FLAG_KERNING ( 1L << 6 )\n#define FT_FACE_FLAG_FAST_GLYPHS ( 1L << 7 )\n#define FT_FACE_FLAG_MULTIPLE_MASTERS ( 1L << 8 )\n#define FT_FACE_FLAG_GLYPH_NAMES ( 1L << 9 )\n#define FT_FACE_FLAG_EXTERNAL_STREAM ( 1L << 10 )\n#define FT_FACE_FLAG_HINTER ( 1L << 11 )\n#define FT_FACE_FLAG_CID_KEYED ( 1L << 12 )\n#define FT_FACE_FLAG_TRICKY ( 1L << 13 )\n#define FT_FACE_FLAG_COLOR ( 1L << 14 )\n#define FT_FACE_FLAG_VARIATION ( 1L << 15 )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_HAS_HORIZONTAL\n *\n * @description:\n * A macro that returns true whenever a face object contains horizontal\n * metrics (this is true for all font formats though).\n *\n * @also:\n * @FT_HAS_VERTICAL can be used to check for vertical metrics.\n *\n */\n#define FT_HAS_HORIZONTAL( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_HORIZONTAL ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_HAS_VERTICAL\n *\n * @description:\n * A macro that returns true whenever a face object contains real\n * vertical metrics (and not only synthesized ones).\n *\n */\n#define FT_HAS_VERTICAL( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_VERTICAL ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_HAS_KERNING\n *\n * @description:\n * A macro that returns true whenever a face object contains kerning data\n * that can be accessed with @FT_Get_Kerning.\n *\n */\n#define FT_HAS_KERNING( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_KERNING ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_IS_SCALABLE\n *\n * @description:\n * A macro that returns true whenever a face object contains a scalable\n * font face (true for TrueType, Type~1, Type~42, CID, OpenType/CFF, and\n * PFR font formats).\n *\n */\n#define FT_IS_SCALABLE( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_SCALABLE ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_IS_SFNT\n *\n * @description:\n * A macro that returns true whenever a face object contains a font whose\n * format is based on the SFNT storage scheme.

This implies\n * the following scheme:\n *\n * First, available or installed font faces are uniquely identified by\n * @FTC_FaceID values, provided to the cache by the client. Note that\n * the cache only stores and compares these values, and doesn't try to\n * interpret them in any way.\n *\n * Second, the cache calls, only when needed, a client-provided function\n * to convert an @FTC_FaceID into a new @FT_Face object. The latter is\n * then completely managed by the cache, including its termination\n * through @FT_Done_Face. To monitor termination of face objects, the\n * finalizer callback in the `generic` field of the @FT_Face object can\n * be used, which might also be used to store the @FTC_FaceID of the\n * face.\n *\n * Clients are free to map face IDs to anything else. The most simple\n * usage is to associate them to a (pathname,face_index) pair that is\n * used to call @FT_New_Face. However, more complex schemes are also\n * possible.\n *\n * Note that for the cache to work correctly, the face ID values must be\n * **persistent**, which means that the contents they point to should not\n * change at runtime, or that their value should not become invalid.\n *\n * If this is unavoidable (e.g., when a font is uninstalled at runtime),\n * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let\n * the cache get rid of any references to the old @FTC_FaceID it may keep\n * internally. Failure to do so will lead to incorrect behaviour or even\n * crashes.\n *\n * To use the cache, start with calling @FTC_Manager_New to create a new\n * @FTC_Manager object, which models a single cache instance. You can\n * then look up @FT_Face and @FT_Size objects with\n * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.\n *\n * If you want to use the charmap caching, call @FTC_CMapCache_New, then\n * later use @FTC_CMapCache_Lookup to perform the equivalent of\n * @FT_Get_Char_Index, only much faster.\n *\n * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then\n * later use @FTC_ImageCache_Lookup to retrieve the corresponding\n * @FT_Glyph objects from the cache.\n *\n * If you need lots of small bitmaps, it is much more memory efficient to\n * call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This\n * returns @FTC_SBitRec structures, which are used to store small bitmaps\n * directly. (A small bitmap is one whose metrics and dimensions all fit\n * into 8-bit integers).\n *\n * We hope to also provide a kerning cache in the near future.\n *\n *\n * @order:\n * FTC_Manager\n * FTC_FaceID\n * FTC_Face_Requester\n *\n * FTC_Manager_New\n * FTC_Manager_Reset\n * FTC_Manager_Done\n * FTC_Manager_LookupFace\n * FTC_Manager_LookupSize\n * FTC_Manager_RemoveFaceID\n *\n * FTC_Node\n * FTC_Node_Unref\n *\n * FTC_ImageCache\n * FTC_ImageCache_New\n * FTC_ImageCache_Lookup\n *\n * FTC_SBit\n * FTC_SBitCache\n * FTC_SBitCache_New\n * FTC_SBitCache_Lookup\n *\n * FTC_CMapCache\n * FTC_CMapCache_New\n * FTC_CMapCache_Lookup\n *\n *************************************************************************/\n\n\n /*************************************************************************/\n /*************************************************************************/\n /*************************************************************************/\n /***** *****/\n /***** BASIC TYPE DEFINITIONS *****/\n /***** *****/\n /*************************************************************************/\n /*************************************************************************/\n /*************************************************************************/\n\n\n /**************************************************************************\n *\n * @type:\n * FTC_FaceID\n *\n * @description:\n * An opaque pointer type that is used to identity face objects.

Sometimes the\n * vertical stems may be only partially black. In this context,\n * 'antialiasing' means that stems are not positioned exactly on pixel\n * borders, causing a fuzzy appearance.\n *\n * There are two principles behind this approach.\n *\n * 1) No hinting in the horizontal direction: Unlike 'superhinted'\n * TrueType, which changes glyph widths to accommodate regular\n * inter-glyph spacing, Adobe's approach is 'faithful to the design' in\n * representing both the glyph width and the inter-glyph spacing designed\n * for the font. This makes the screen display as close as it can be to\n * the result one would get with infinite resolution, while preserving\n * what is considered the key characteristics of each glyph. Note that\n * the distances between unhinted and grid-fitted positions at small\n * sizes are comparable to kerning values and thus would be noticeable\n * (and distracting) while reading if hinting were applied.\n *\n * One of the reasons to not hint horizontally is antialiasing for LCD\n * screens: The pixel geometry of modern displays supplies three vertical\n * subpixels as the eye moves horizontally across each visible pixel. On\n * devices where we can be certain this characteristic is present a\n * rasterizer can take advantage of the subpixels to add increments of\n * weight. In Western writing systems this turns out to be the more\n * critical direction anyway; the weights and spacing of vertical stems\n * (see above) are central to Armenian, Cyrillic, Greek, and Latin type\n * designs. Even when the rasterizer uses greyscale antialiasing instead\n * of color (a necessary compromise when one doesn't know the screen\n * characteristics), the unhinted vertical features preserve the design's\n * weight and spacing much better than aliased type would.\n *\n * 2) Alignment in the vertical direction: Weights and spacing along the\n * y~axis are less critical; what is much more important is the visual\n * alignment of related features (like cap-height and x-height). The\n * sense of alignment for these is enhanced by the sharpness of grid-fit\n * edges, while the cruder vertical resolution (full pixels instead of\n * 1/3 pixels) is less of a problem.\n *\n * On the technical side, horizontal alignment zones for ascender,\n * x-height, and other important height values (traditionally called\n * 'blue zones') as defined in the font are positioned independently,\n * each being rounded to the nearest pixel edge, taking care of overshoot\n * suppression at small sizes, stem darkening, and scaling.\n *\n * Hstems (this is, hint values defined in the font to help align\n * horizontal features) that fall within a blue zone are said to be\n * 'captured' and are aligned to that zone. Uncaptured stems are moved\n * in one of four ways, top edge up or down, bottom edge up or down.\n * Unless there are conflicting hstems, the smallest movement is taken to\n * minimize distortion.\n *\n */\n\n\n /**************************************************************************\n *\n * @section:\n * pcf_driver\n *\n * @title:\n * The PCF driver\n *\n * @abstract:\n * Controlling the PCF driver module.\n *\n * @description:\n * While FreeType's PCF driver doesn't expose API functions by itself, it\n * is possible to control its behaviour with @FT_Property_Set and\n * @FT_Property_Get.

The following lists the available properties\n * together with the necessary macros and structures.\n *\n * The TrueType driver's module name is 'truetype'.\n *\n * A single property @interpreter-version is available, as documented in\n * the @properties section.\n *\n * We start with a list of definitions, kindly provided by Greg\n * Hitchcock.\n *\n * _Bi-Level Rendering_\n *\n * Monochromatic rendering, exclusively used in the early days of\n * TrueType by both Apple and Microsoft. Microsoft's GDI interface\n * supported hinting of the right-side bearing point, such that the\n * advance width could be non-linear. Most often this was done to\n * achieve some level of glyph symmetry. To enable reasonable\n * performance (e.g., not having to run hinting on all glyphs just to get\n * the widths) there was a bit in the head table indicating if the side\n * bearing was hinted, and additional tables, 'hdmx' and 'LTSH', to cache\n * hinting widths across multiple sizes and device aspect ratios.\n *\n * _Font Smoothing_\n *\n * Microsoft's GDI implementation of anti-aliasing. Not traditional\n * anti-aliasing as the outlines were hinted before the sampling. The\n * widths matched the bi-level rendering.\n *\n * _ClearType Rendering_\n *\n * Technique that uses physical subpixels to improve rendering on LCD\n * (and other) displays. Because of the higher resolution, many methods\n * of improving symmetry in glyphs through hinting the right-side bearing\n * were no longer necessary. This lead to what GDI calls 'natural\n * widths' ClearType, see\n * http://rastertragedy.com/RTRCh4.htm#Sec21. Since hinting\n * has extra resolution, most non-linearity went away, but it is still\n * possible for hints to change the advance widths in this mode.\n *\n * _ClearType Compatible Widths_\n *\n * One of the earliest challenges with ClearType was allowing the\n * implementation in GDI to be selected without requiring all UI and\n * documents to reflow. To address this, a compatible method of\n * rendering ClearType was added where the font hints are executed once\n * to determine the width in bi-level rendering, and then re-run in\n * ClearType, with the difference in widths being absorbed in the font\n * hints for ClearType (mostly in the white space of hints); see\n * http://rastertragedy.com/RTRCh4.htm#Sec20. Somewhat by\n * definition, compatible width ClearType allows for non-linear widths,\n * but only when the bi-level version has non-linear widths.\n *\n * _ClearType Subpixel Positioning_\n *\n * One of the nice benefits of ClearType is the ability to more crisply\n * display fractional widths; unfortunately, the GDI model of integer\n * bitmaps did not support this. However, the WPF and Direct Write\n * frameworks do support fractional widths. DWrite calls this 'natural\n * mode', not to be confused with GDI's 'natural widths'. Subpixel\n * positioning, in the current implementation of Direct Write,\n * unfortunately does not support hinted advance widths, see\n * http://rastertragedy.com/RTRCh4.htm#Sec22. Note that the\n * TrueType interpreter fully allows the advance width to be adjusted in\n * this mode, just the DWrite client will ignore those changes.\n *\n * _ClearType Backward Compatibility_\n *\n * This is a set of exceptions made in the TrueType interpreter to\n * minimize hinting techniques that were problematic with the extra\n * resolution of ClearType; see\n * http://rastertragedy.com/RTRCh4.htm#Sec1 and\n * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.\n * This technique is not to be confused with ClearType compatible widths.\n * ClearType backward compatibility has no direct impact on changing\n * advance widths, but there might be an indirect impact on disabling\n * some deltas. This could be worked around in backward compatibility\n * mode.\n *\n * _Native ClearType Mode_\n *\n * (Not to be confused with 'natural widths'.) This mode removes all the\n * exceptions in the TrueType interpreter when running with ClearType.\n * Any issues on widths would still apply, though.\n *\n */\n\n\n /**************************************************************************\n *\n * @section:\n * properties\n *\n * @title:\n * Driver properties\n *\n * @abstract:\n * Controlling driver modules.\n *\n * @description:\n * Driver modules can be controlled by setting and unsetting properties,\n * using the functions @FT_Property_Set and @FT_Property_Get.

'e' is the error\n * code identifier (e.g., `Invalid_Argument`), 'v' is the error's\n * numerical value, and 's' is the corresponding error string.\n *\n * ```\n * FT_ERROR_END_LIST\n * ```\n *\n * This macro ends the list.\n *\n * Additionally, you have to undefine `FTERRORS_H_` before #including\n * this file.\n *\n * Here is a simple example.\n *\n * ```\n * #undef FTERRORS_H_\n * #define FT_ERRORDEF( e, v, s ) { e, s },\n * #define FT_ERROR_START_LIST {\n * #define FT_ERROR_END_LIST { 0, NULL } };\n *\n * const struct\n * {\n * int err_code;\n * const char* err_msg;\n * } ft_errors[] =\n *\n * #include FT_ERRORS_H\n * ```\n *\n * An alternative to using an array is a switch statement.\n *\n * ```\n * #undef FTERRORS_H_\n * #define FT_ERROR_START_LIST switch ( error_code ) {\n * #define FT_ERRORDEF( e, v, s ) case v: return s;\n * #define FT_ERROR_END_LIST }\n * ```\n *\n * If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should\n * be replaced with `FT_ERROR_BASE(error_code)` in the last example.\n */\n\n /* */\n\n /* In previous FreeType versions we used `__FTERRORS_H__`.

These technologies are\n * controlled differently and API described below, although always\n * available, performs its function when appropriate method is enabled\n * and does nothing otherwise.\n *\n * ClearType-style LCD rendering exploits the color-striped structure of\n * LCD pixels, increasing the available resolution in the direction of\n * the stripe (usually horizontal RGB) by a factor of~3. Using the\n * subpixels coverages unfiltered can create severe color fringes\n * especially when rendering thin features. Indeed, to produce\n * black-on-white text, the nearby color subpixels must be dimmed\n * equally.\n *\n * A good 5-tap FIR filter should be applied to subpixel coverages\n * regardless of pixel boundaries and should have these properties:\n *\n * 1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid\n * any shifts in appearance.\n *\n * 2. It should be color-balanced, meaning a~+ b~=~c, to reduce color\n * fringes by distributing the computed coverage for one subpixel to\n * all subpixels equally.\n *\n * 3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain\n * overall brightness.\n *\n * Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less\n * forgiving of non-ideal gamma curves of a screen (and viewing angles),\n * beveled filters are fuzzier but more tolerant.\n *\n * Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights\n * API to specify a low-pass filter, which is then applied to\n * subpixel-rendered bitmaps generated through @FT_Render_Glyph.\n *\n * Harmony LCD rendering is suitable to panels with any regular subpixel\n * structure, not just monitors with 3 color striped subpixels, as long\n * as the color subpixels have fixed positions relative to the pixel\n * center. In this case, each color channel is then rendered separately\n * after shifting the outline opposite to the subpixel shift so that the\n * coverage maps are aligned. This method is immune to color fringes\n * because the shifts do not change integral coverage.\n *\n * The subpixel geometry must be specified by xy-coordinates for each\n * subpixel. By convention they may come in the RGB order: {{-1/3, 0},\n * {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},\n * {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.\n *\n * Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.\n * If one follows the RGB order convention, the same order applies to the\n * resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps. Note,\n * however, that the coordinate frame for the latter must be rotated\n * clockwise. Harmony with default LCD geometry is equivalent to\n * ClearType with light filter.\n *\n * As a result of ClearType filtering or Harmony rendering, the\n * dimensions of LCD bitmaps can be either wider or taller than the\n * dimensions of the corresponding outline with regard to the pixel grid.\n * For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to\n * the left, and 2~subpixels to the right. The bitmap offset values are\n * adjusted accordingly, so clients shouldn't need to modify their layout\n * and glyph positioning code when enabling the filter.\n *\n * The ClearType and Harmony rendering is applicable to glyph bitmaps\n * rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and\n * @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V\n * is specified. This API does not control @FT_Outline_Render and\n * @FT_Outline_Get_Bitmap.\n *\n * The described algorithms can completely remove color artefacts when\n * combined with gamma-corrected alpha blending in linear space. Each of\n * the 3~alpha values (subpixels) must by independently used to blend one\n * color channel. That is, red alpha blends the red channel of the text\n * color with the red channel of the background pixel.\n */\n\n\n /**************************************************************************\n *\n * @enum:\n * FT_LcdFilter\n *\n * @description:\n * A list of values to identify various types of LCD filters.\n *\n * @values:\n * FT_LCD_FILTER_NONE ::\n * Do not perform filtering.

However, we might be\n * interested in introducing more complex and powerful algorithms in the\n * future, like the one described in the John D. Hobby paper, which\n * unfortunately requires a lot more horsepower.\n *\n * Because a sufficiently sophisticated font management system would\n * typically implement an LRU cache of opened face objects to reduce memory\n * usage, it is a good idea to be able to avoid recomputing global hints\n * every time the same face is re-opened.\n *\n * We thus provide the ability to cache global hints outside of the face\n * object, in order to speed up font re-opening time. Of course, this\n * feature is purely optional, so most client programs won't even notice\n * it.\n *\n * I initially thought that it would be a good idea to cache the glyph\n * hints too. However, my general idea now is that if you really need to\n * cache these too, you are simply in need of a new font format, where all\n * this information could be stored within the font file and decoded on the\n * fly.\n *\n */\n\n\n#include \n#include FT_FREETYPE_H\n\n\nFT_BEGIN_HEADER\n\n\n typedef struct FT_AutoHinterRec_ *FT_AutoHinter;\n\n\n /**************************************************************************\n *\n * @functype:\n * FT_AutoHinter_GlobalGetFunc\n *\n * @description:\n * Retrieve the global hints computed for a given face object.

\n *\n * \\section intro Introduction\n *\n * Welcome to the irrKlang API documentation. This page should give you a short overview \n * over irrKlang, the high level audio library. \n * In this documentation files you'll find any information you'll need to develop applications with\n * irrKlang using C++. If you are looking for a tutorial on how to start, you'll\n * find some on the homepage of irrKlang at\n * http://www.ambiera.com/irrklang\n * or inside the SDK in the directory \\examples.\n *\n * The irrKlang library is intended to be an easy-to-use 3d and 2d sound engine, so\n * this documentation is an important part of it. If you have any questions or\n * suggestions, please take a look into the ambiera.com forum or just send a mail.\n *\n *

\n *\n *\n *\n * \\section tipsandtricks Tips and Tricks\n *\n * This section lists a few tips you might consider when implementing the sound part of your application\n * using irrKlang:\n *\n *
    \n *
  • If you can choose which audio file format is the primary one for your application,\n *\t\t\t\t\t use .OGG files, instead of for example .MP3 files. irrKlang uses a lot less memory\n * and CPU power when playing .OGGs.
    • \n *
  • To keep your application simple, each time you play a sound, you can use for example\n * play2D(\"filename.mp3\") and let irrKlang handle the rest. There is no need to implement\n * a preloading/caching/file management system for the audio playback. irrKlang will handle\n * all this by itself and will never load a file twice.
    • \n *
  • irrKlang is crashing in your application? This should not happen, irrKlang is pretty stable,\n * and in most cases, this is a problem in your code: In a lot of cases the reason is simply\n * a wrong call to irrklang::IRefCounted::drop(). Be sure you are doing it correctly. (If you are unsure,\n * temporarily remove all calls to irrklang::IRefCounted::drop() and see if this helps.)
    • \n *

\n *
\n *
\n *
\n *\n *\n *\n * \\section concept Starting up the Engine\n *\n * irrKlang is designed so that it is very easy to achieve everything, its interface should\n * be very simple to use. The @ref quickstartexample shows how to play and mp3 file, and there\n * is another example, @ref quickstartexample2, showing some few more details.
\n * To start up the sound engine, you simply need to call createIrrKlangDevice(). To shut it down,\n * call IRefCounted::drop():\n *\n * \\code\n * #include \n *\n * // ...\n *\n * // start up the engine\n * irrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();\n *\t\n * // ...\n * \n * // after finished,\n * // close the engine again, similar as calling 'delete'\n * engine->drop(); \n * \\endcode\n *\n * The createIrrKlangDevice() function also accepts several parameters, so that you can \n * specify which sound driver should be used, if plugins should be used, if irrKlang\n * should run in multithreaded mode, and similar.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section playingSounds Playing Sounds\n *\n * Once you have irrKlang running (like in @ref concept), you can start playing sounds:\n *\n * \\code\n * engine->play2D(\"someSoundFile.wav\"); \n * \\endcode\n *\n * This works with all supported file types. You can replace \"someSoundFile.wav\" with\n * \"someSoundFile.mp3\", or \"someSoundFile.ogg\", for example.
\n * To play a sound looped, set the second parameter to 'true':\n *\n * \\code\n * engine->play2D(\"myMusic.mp3\", true); \n * \\endcode \n *\n * To stop this looping sound again, use engine->\\link irrklang::ISoundEngine::stopAllSounds stopAllSounds()\\endlink to stop all sounds, or\n * irrklang::ISound::stop() if you only want to stop that single sound. @ref changingSounds\n * shows how to get to that ISound interface.\n *
\n *
\n *
\n *
\n *\n *\n * \\section changingSounds Influencing Sounds during Playback\n * To influence parameters of the sound such as pan, volume or playback speed during runtime, \n * to get the play position or stop playback of single playing sounds,\n * you can use the irrklang::ISound interface. \n * irrklang::ISoundEngine::play2D (but also play3D) returns\n * a pointer to this interface when its third ('startPaused') or fourth ('track') parameter\n * was set to true:\n *\n * \\code\n * irrklang::ISound* snd = engine->play2D(\"myMusic.mp3\", true, false, true); \n *\n * // ...\n *\n * if (snd)\n * snd->setVolume(someNewValue);\n * \n * // ...\n * \n * if (snd)\n * {\n * snd->drop(); // don't forget to release the pointer once it is no longer needed by you\n * snd = 0;\n * }\n * \\endcode\n *\n * The irrklang::ISound interface can also be used to test if the sound has been finished, \n * set event receivers, pause and unpause sounds and similar. \n *
\n *
\n *
\n *
\n *\n *\n * \\section soundSources Using Sound Sources\n *\n * To be more flexible playing back sounds, irrKlang uses the concept of sound sources. \n * A sound source can be simply the name of a sound file, such as \"sound.wav\". It is possible\n * to add \"sound.wav\" as sound source to irrKlang, and play it using the sound source pointer:\n *\n * \\code\n * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile(\"shoot.wav\"); \n *\n * engine->play2D(shootSound);\n *\n * // note: you don't need to drop() the shootSound if you don't use it anymore\n * \\endcode\n *\n * The advantage of using irrklang::ISoundSource is that it is possible to set \n * default values for this source, such\n * as volume or distances if it should be used as 3D sound:\n *\n * \\code\n * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile(\"shoot.wav\"); \n *\n * shootSound->setDefaultVolume(0.5f);\n *\n * // shootSound will now be played with half its sound volume by default:\n * engine->play2D(shootSound);\n * \\endcode\n *\n * It is also possible to have multiple settings for the same sound file:\n *\n * \\code\n * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile(\"shoot.wav\"); \n * irrklang::ISoundSource* shootSound2 = engine->addSoundSourceAlias(shootSound, \"silentShoot\"); \n *\n * shootSound2->setDefaultVolume(0.1f);\n *\n * // shootSound will now be played with 100% of its sound volume by default,\n * // shootSound2 will now be played 10% of its sound volume by default. It is \n * // also possible to play it using engine->play(\"silentShoot\"), now.\n * \\endcode\n *\n * Using addSoundSourceFromMemory(), it is also possible to play sounds back directly from memory,\n * without files.\n * Of course, it is not necessary to use sound sources. Using irrklang::ISound, it is\n * possible to change the settings of all sounds, too. But using sound sources, it is\n * not necessary to do this every time a sound is played.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section sound3d 3D Sound\n *\n * There is nothing difficult in playing sounds in 3D using irrKlang: Instead of using \n * irrklang::ISoundEngine::play2D(), just use irrklang::ISoundEngine::play3D(), which\n * takes a 3D position as additional parameter:\n *\n * \\code\n * irrklang::vec3df position(23,70,90);\n * engine->play3D(\"yourSound.wav\", position);\n * \\endcode\n *\n * But to make it sound realistic, you need to set a minimal sound\n * distance: If your sound is caused by a bee, it will usually have a smaller\n * sound radius than for example a jet engine. You can set default values using sound sources\n * (see @ref soundSources) or set these values after you have started the sound paused:\n *\n * \\code\n * irrklang::vec3df position(23,70,90);\n *\n * // start the sound paused:\n * irrklang::ISound* snd = engine->play3D(\"yourSound.wav\", position, false, true);\n *\n * if (snd)\n * {\n * snd->setMinDistance(30.0f); // a loud sound\n * snd->setIsPaused(false); // unpause the sound\n * }\n * \\endcode\n * \n * There is also the possibility to change the maxDistance, but it is only necessary to change this\n * in very rare circumstances.\n * If the sound moves, it is also a good idea to update its position from time to time:\n * \n * \\code\n * if (snd)\n * snd->setPosition(newPosition);\n * \\endcode\n *\n * And don't forget to drop() the sound after you don't need it anymore. If you do, it's \n * nothing severe because irrKlang will still clean up the sounds resources after it has\n * finished, but you still would waste some few bytes of memory:\n * \n * \\code\n * if (snd)\n * {\n * snd->drop();\n * snd = 0;\n * }\n * \\endcode\n *\n * To update the position of yourself, the listener of the 3D sounds, use this from\n * time to time:\n *\n * \\code\n * irrklang::vec3df position(0,0,0); // position of the listener\n * irrklang::vec3df lookDirection(10,0,10); // the direction the listener looks into\n * irrklang::vec3df velPerSecond(0,0,0); // only relevant for doppler effects\n * irrklang::vec3df upVector(0,1,0); // where 'up' is in your 3D scene\n *\n * engine->setListenerPosition(position, lookDirection, velPerSecond, upVector);\n * \\endcode\n *\n *
\n *
\n *
\n *
\n *\n *\n * \\section removingSounds Removing Sounds\n *\n * irrKlang manages the memory usage of sounds by itself, so usually, you don't have\n * to care about memory management. But if you know you need to reduce the\n * amount of used memory at a certain point in your program, you can do this:\n *\n * \\code\n * engine->removeAllSoundSources(); \n * \\endcode\n *\n * This will remove all sounds and also cause all sounds to be stopped. To remove single\n * sounds from the engine, use:\n *\n * \\code\n * engine->removeSoundSource(pointerToSomeSoundSource); \n * // or:\n * engine->removeSoundSource(\"nameOfASoundFile.wav\"); \n * \\endcode\n *\n * Note: Only removing buffered sounds will reduce the amount of memory used by irrKlang, streamed\n * sounds don't occupy a lot of memory when they are not played.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section events Using Sound Events\n *\n * In order to wait for a sound to be finished, it is simply possible to \n * poll irrklang::ISound::isFinished(). Another way would be to constantly use \n * irrklang::ISoundEngine::isCurrentlyPlaying to test wether a sound with that name or source\n * is currently playing. But of course, an event based approach is a lot nicer. That's why irrKlang\n * supports sound events.
\n * The key to sound events is the method \n * \\link irrklang::ISound::setSoundStopEventReceiver setSoundStopEventReceiver \\endlink\n * of the irrklang::ISound interface\n * (See @ref changingSounds on how to get the ISound interface):\n *\n * \\code\n * irrklang::ISound* snd = engine->play2D(\"speech.mp3\", false, false, true); \n * if (snd)\n * snd->setSoundStopEventReceiver(yourEventReceiver, 0);\n * \\endcode\n * \n * The optional second parameter of setSoundStopEventReceiver is a user pointer, set it to whatever you like.\n * 'yourEventReceiver' must be an implementation of the irrklang::ISoundStopEventReceiver interface.
\n * A whole implementation could look like this:\n *\n * \\code\n * class MySoundEndReceiver : public irrklang::ISoundStopEventReceiver\n * {\n * public:\n * virtual void OnSoundStopped (irrklang::ISound* sound, irrklang::E_STOP_EVENT_CAUSE reason, void* userData)\n * {\n * // called when the sound has ended playing\n * printf(\"sound has ended\");\n * }\n * }\n *\n * // ...\n *\n * MySoundEndReceiver* myReceiver = new MySoundEndReceiver();\n * irrklang::ISound* snd = engine->play2D(\"speech.mp3\", false, false, true); \n * if (snd)\n * snd->setSoundStopEventReceiver(myReceiver);\n *\n * myReceiver->drop(); // similar to delete\n * \\endcode\n * \n * The irrklang::ISoundStopEventReceiver::OnSoundStopped() method is guaranteed to be called when a sound or sound stream has stopped,\n * either because the sound reached its playback end, its sound source was removed,\n * ISoundEngine::stopAllSounds() has been called or the whole engine was deleted.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section memoryPlayback Memory Playback\n *\n * Using irrKlang, it is easily possible to play sounds directly from memory instead out of \n * files. There is an example project showing this: In the SDK, in /examples/03.MemoryPlayback.\n * But in short, it simply works by adding the memory as sound source (See @ref soundSources for \n * details about sound sources):\n *\n * \\code\n * engine->addSoundSourceFromMemory(pointerToMemory, memorySize, \"nameforthesound.wav\");\n * \n * // play sound now\n * engine->play2D(\"nameforthesound.wav\");\n * \\endcode\n *\n * Or using a sound source pointer:\n *\n * \\code\n * irrklang::ISoundSource* snd = \n * engine->addSoundSourceFromMemory(pointerToMemory, memorySize, \"nameforthesound.wav\");\n * \n * // play sound now\n * engine->play2D(snd);\n * \\endcode\n *\n * Note: It is also possible to overwrite the file access directly, don't use this Memory Playback\n * feature for this. See @ref fileOverriding for details.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section effects Sound Effects\n *\n * irrKlang supports the effects Chorus, Compressor, Distortion, Echo, Flanger\n * Gargle, 3DL2Reverb, ParamEq and WavesReverb, when using the sound driver \n * irrklang::ESOD_DIRECT_SOUND_8, which selected by default when using Windows.
\n *\n * Using the irrklang::ISound interface, you can obtain the irrklang::ISoundEffectControl\n * interface if the sound device supports sound effects and the last parameter ('enableSoundEffects')\n * was set to true when calling play2D():\n *\n * \\code\n * irrklang::ISound* snd = engine->play2D(\"sound.wav\", true, false, true, ESM_AUTO_DETECT, true);\n *\n * if (snd)\n * {\n * irrklang::ISoundEffectControl* fx = snd->getSoundEffectControl();\n * if (fx)\n * {\n * // enable the echo sound effect for this sound\n * fx->enableEchoSoundEffect();\n * }\n * }\n * \n * snd->drop();\n * \\endcode\n *\n * This enabled the echo sound effect for this sound. The method also supports a lot of \n * parameters, and can be called multiple times to change those parameters over time if wished.\n * There are a lot of other sound effects, see irrklang::ISoundEffectControl for details.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section fileOverriding Overriding File Access\n *\n * It is possible to let irrKlang use your own file access functions.\n * This is useful if you want to read sounds from other sources than\n * just files, for example from custom internet streams or \n * an own encrypted archive format. There is an example in the SDK in \n * examples/04.OverrideFileAccess which shows this as well.
\n *\n * The only thing to do for this is to implement your own irrklang::IFileFactory,\n * and set it in irrKlang using irrklang::ISoundEngine::addFileFactory():\n *\n * \\code\n * // a class implementing the IFileFactory interface to override irrklang file access\n * class CMyFileFactory : public irrklang::IFileFactory\n * {\n * public:\n *\n * // Opens a file for read access. Simply return 0 if file not found.\n * virtual irrklang::IFileReader* createFileReader(const ik_c8* filename)\n * {\n * // return your own irrklang::IFileReader implementation here, for example like that:\n * return new CMyReadFile(filename);\n * }\n * };\n * \n * // ...\n *\n * CMyFileFactory* myFactory = new CMyFileFactory();\n * engine->addFileFactory(myFactory);\n * myFactory->drop();\n * \\endcode\n *\n * For a full example implementation, just take a look into the SDK in examples/04.OverrideFileAccess.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section audioDecoders Adding Audio Decoders\n *\n * To add support for new file formats, it is possible to add new audio decoders\n * to irrKlang. \n * The only thing to do for this is to implement your own irrklang::IAudioStreamLoader,\n * and irrklang::IAudioStream, and set it in irrKlang using \n * irrklang::ISoundEngine::registerAudioStreamLoader():\n *\n * \\code\n * class NewAudioStreamLoader : public irrklang::IAudioStreamLoader\n * {\n * // ... returns NewAudioDecoder and the used file name suffices.\n * };\n *\n * class NewAudioDecoder : public irrklang::IAudioStream\n * {\n * public:\n * // ... decodes the new file format\n * };\n *\n * // ...\n *\n * NewAudioDecoder* loader = new NewAudioDecoder();\n * engine->registerAudioStreamLoader(loader);\n * loader->drop();\n * \\endcode\n * \n * There is an example audio decoder and loader with full source in plugins/ikpMP3, which\n * adds MP3 audio decoding capabilities to irrKlang.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section plugins Creating irrKlang Plugins\n *\n * irrKlang plugins are ikp*.dll (Windows), ikp*.so (Unix) or ikp*.dylib (MacOS) \n * files which are loaded by irrKlang at startup when the \n * irrklang::ESEO_LOAD_PLUGINS was set (which is default) or\n * irrklang::ISoundEngine::loadPlugins() was called.
\n *\n * The plugin only needs to contain the following function which will be called by irrKlang:\n *\n * \\code\n * #ifdef WIN32\n * // Windows version\n * __declspec(dllexport) void __stdcall irrKlangPluginInit(ISoundEngine* engine, const char* version)\n * #else\n * // Linux and Mac OS version\n * void irrKlangPluginInit(ISoundEngine* engine, const char* version)\n * #endif\n * {\n * // your implementation here\n * }\n * \\endcode\n *\n * In there, it is for example possible to extend irrKlang with new audio decoders,\n * see @ref audioDecoders for details.
\n * \n * There is an example plugin with full source in plugins/ikpMP3, which\n * adds MP3 audio decoding capabilities to irrKlang.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section staticLib Using irrKlang as static Lib\n *\n * If you don't want to use the irrKlang.DLL file and link irrKlang statically, you can do this\n * by simply linking to the irrKlang.lib in the bin/win32-visualstudio_lib folder. This folder\n * will only available in the pro versions of irrKlang, which you get when purchasing an irrKlang\n * license.\n *\n * To use irrKlang in this way, just define IRRKLANG_STATIC before including irrklang.h, like this:\n *\n * \\code\n * #define IRRKLANG_STATIC\n * #include \n * \\endcode\n *\n * Of course, IRRKLANG_STATIC can also simply be defined in the project/compiler settings instead of\n * in the source file.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section enumeratingDevices Enumerating sound devices\n *\n * irrKlang uses the default sound device when playing sound when started without parameters. But if you want\n * irrKlang to playback sound on one specific sound device, you may want to enumerate the available\n * sound devices on your system and select one of them. Use irrklang::createSoundDeviceList() for this. \n * This example code shows how to print a list of all available sound devices on the current system and lets\n * the user choose one of them: \n *\n * \\code\n * int main(int argc, const char** argv)\n * {\n *\t// enumerate devices\n * \n * \tirrklang::ISoundDeviceList* deviceList = createSoundDeviceList();\n * \n * \t// ask user for a sound device\n * \n * \tprintf(\"Devices available:\\n\\n\");\n * \n * \tfor (int i=0; igetDeviceCount(); ++i)\n * \t\tprintf(\"%d: %s\\n\", i, deviceList->getDeviceDescription(i));\n * \n * \tprintf(\"\\nselect a device using the number (or press any key to use default):\\n\\n\");\n * \tint deviceNumber = getch() - '0';\n * \n * \t// create device with the selected driver\n * \n * \tconst char* deviceID = deviceList->getDeviceID(deviceNumber);\n * \t\t\n * \tISoundEngine* engine = createIrrKlangDevice(irrklang::ESOD_AUTO_DETECT, \n * \t irrklang::ESEO_DEFAULT_OPTIONS,\n * \t deviceID);\n * \n * \tdeviceList->drop(); // delete device list\n *\n * // ... use engine now\n * } \n * \\endcode\n *\n * In this way, it is also possible to play back sound using two devices at the same time: Simply \n * create two irrKlang devices with each a different deviceID.
\n * Note: createSoundDeviceList() takes a driver type parameter (such as irrklang::ESOD_DIRECT_SOUND8), which you\n * have to set to the same value as the first parameter you want to use with createIrrKlangDevice(), if it is \n * other than irrklang::ESOD_AUTO_DETECT.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section recordingAudio Recording Audio\n *\n * irrKlang is able to record audio from sound capturing devices such as microphones (currently only \n * supported in windows). Use the irrklang::IAudioRecorder interface to do this. The following example shows how\n * to record some audio and play it back again using the engine: \n *\n * \\code\n * int main(int argc, const char** argv)\n * {\n *\tirrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();\n *\tirrklang::IAudioRecorder* recorder = irrklang::createIrrKlangAudioRecorder(engine);\n *\n *\tif (!engine || !recorder)\n *\t{\n *\t\tprintf(\"Could not create audio engine or audio recorder\\n\");\n *\t\treturn 1;\n *\t}\n *\n *\tprintf(\"\\nPress any key to start recording audio...\\n\");\n *\tgetch();\n *\n *\t// record some audio\n *\n *\trecorder->startRecordingBufferedAudio();\n *\n *\tprintf(\"\\nRECORDING. Press any key to stop...\\n\");\n *\tgetch();\n *\n *\trecorder->stopRecordingAudio();\n *\n *\tprintf(\"\\nRecording done, recorded %dms of audio.\\n\", \n *\t\trecorder->getAudioFormat().FrameCount * 1000 / recorder->getAudioFormat().SampleRate );\n *\tprintf(\"Press any key to play back recorded audio...\\n\");\n *\tgetch();\n *\n *\t// play the recorded audio\n *\trecorder->addSoundSourceFromRecordedAudio(\"myRecordedVoice\");\n *\tengine->play2D(\"myRecordedVoice\", true);\n *\n *\t// wait until user presses a key\n *\tprintf(\"\\nPress any key to quit...\");\n *\tgetch();\n *\n *\trecorder->drop();\n *\tengine->drop(); // delete engine\n *\n *\treturn 0;\n * } \n * \\endcode\n *\n * In order to select a specific audio capturing device for recording, it is necessary to enumerate\n * the available devices. Simply replace the first to lines of code of the example above with code\n * like this to list all devices and select one:\n *\n * \\code\n * // enumerate recording devices and ask user to select one\n * \n * irrklang::ISoundDeviceList* deviceList = irrklang::createAudioRecorderDeviceList();\n *\n * printf(\"Devices available:\\n\\n\");\n *\n * for (int i=0; igetDeviceCount(); ++i)\n * printf(\"%d: %s\\n\", i, deviceList->getDeviceDescription(i));\n *\n * printf(\"\\nselect a device using the number (or press any key to use default):\\n\\n\");\n * int deviceNumber = getch() - '0';\n *\n * // create recording device with the selected driver\n *\n * const char* deviceID = deviceList->getDeviceID(deviceNumber);\n * irrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();\n * irrklang::IAudioRecorder* recorder = \n * irrklang::createIrrKlangAudioRecorder(engine, irrklang::ESOD_AUTO_DETECT, deviceID);\n *\n * \\endcode\n *\n *
\n *
\n *
\n *
\n *\n *\n * \\section unicode Unicode support\n *\n * irrKlang supports unicode on all operating systems. Internally, it uses UTF8, and all functions accepting strings\n * and file names take UTF8 strings. If you are running irrKlang on Windows, and are using the UNICODE define or using\n * wchar_t* strings directly, you can do this as well. Use the irrKlang provided function makeUTF8fromUTF16string() to \n * convert your wchar_t* string to a char* string.\n *\n * This example shows how:\n *\n * \\code\n * const wchar_t* yourFilename = L\"SomeUnicodeFilename.wav\"; // assuming this is the file name you get from some of your functions\n *\n * const int nBufferSize = 2048; // large enough, but best would be wcslen(yourFilename)*3.\n * char strBuffer[nBufferSize]; \n * irrklang::makeUTF8fromUTF16string(yourFilename, strBuffer, nBufferSize);\n *\n * // now the converted file name is in strBuffer. We can play it for example now:\n * engine->play2D(strBuffer);\n * \\endcode\n *\n * Of course, you can use any other unicode conversion function for this. makeUTF8fromUTF16string() is only provided\n * for convenience.\n *
\n *

Since the top-right vertex of the bottom-right triangle is \nlit and the other 2 vertices of the triangle are not, the bright values interpolates to the other 2 vertices.

SSE2 is used by\ndefault, but NEON must be enabled explicitly; see docs.\n\nWith other JPEG optimizations included in this version, we see\n2x speedup on a JPEG on an x86 machine, and a 1.5x speedup\non a JPEG on an ARM machine, relative to previous versions of this\nlibrary. The same results will not obtain for all JPGs and for all\nx86/ARM machines. (Note that progressive JPEGs are significantly\nslower to decode than regular JPEGs.) This doesn't mean that this\nis the fastest JPEG decoder in the land; rather, it brings it\ncloser to parity with standard libraries. If you want the fastest\ndecode, look elsewhere. (See \"Philosophy\" section of docs below.)\n\nSee final bullet items below for more info on SIMD.\n\n- Added STBI_MALLOC, STBI_REALLOC, and STBI_FREE macros for replacing\nthe memory allocator. Unlike other STBI libraries, these macros don't\nsupport a context parameter, so if you need to pass a context into\nthe allocator, you'll have to store it in a global or a thread-local\nvariable.\n\n- Split existing STBI_NO_HDR flag into two flags, STBI_NO_HDR and\nSTBI_NO_LINEAR.\nSTBI_NO_HDR: suppress implementation of .hdr reader format\nSTBI_NO_LINEAR: suppress high-dynamic-range light-linear float API\n\n- You can suppress implementation of any of the decoders to reduce\nyour code footprint by #defining one or more of the following\nsymbols before creating the implementation.\n\nSTBI_NO_JPEG\nSTBI_NO_PNG\nSTBI_NO_BMP\nSTBI_NO_PSD\nSTBI_NO_TGA\nSTBI_NO_GIF\nSTBI_NO_HDR\nSTBI_NO_PIC\nSTBI_NO_PNM (.ppm and .pgm)\n\n- You can request *only* certain decoders and suppress all other ones\n(this will be more forward-compatible, as addition of new decoders\ndoesn't require you to disable them explicitly):\n\nSTBI_ONLY_JPEG\nSTBI_ONLY_PNG\nSTBI_ONLY_BMP\nSTBI_ONLY_PSD\nSTBI_ONLY_TGA\nSTBI_ONLY_GIF\nSTBI_ONLY_HDR\nSTBI_ONLY_PIC\nSTBI_ONLY_PNM (.ppm and .pgm)\n\nNote that you can define multiples of these, and you will get all\nof them (\"only x\" and \"only y\" is interpreted to mean \"only x&y\").\n\n- If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still\nwant the zlib decoder to be available, #define STBI_SUPPORT_ZLIB\n\n- Compilation of all SIMD code can be suppressed with\n#define STBI_NO_SIMD\nIt should not be necessary to disable SIMD unless you have issues\ncompiling (e.g. using an x86 compiler which doesn't support SSE\nintrinsics or that doesn't support the method used to detect\nSSE2 support at run-time), and even those can be reported as\nbugs so I can refine the built-in compile-time checking to be\nsmarter.\n\n- The old STBI_SIMD system which allowed installing a user-defined\nIDCT etc. has been removed. If you need this, don't upgrade. My\nassumption is that almost nobody was doing this, and those who\nwere will find the built-in SIMD more satisfactory anyway.\n\n- RGB values computed for JPEG images are slightly different from\nprevious versions of stb_image. (This is due to using less\ninteger precision in SIMD.) The C code has been adjusted so\nthat the same RGB values will be computed regardless of whether\nSIMD support is available, so your app should always produce\nconsistent results. But these results are slightly different from\nprevious versions. (Specifically, about 3% of available YCbCr values\nwill compute different RGB results from pre-1.49 versions by +-1;\nmost of the deviating values are one smaller in the G channel.)\n\n- If you must produce consistent results with previous versions of\nstb_image, #define STBI_JPEG_OLD and you will get the same results\nyou used to; however, you will not get the SIMD speedups for\nthe YCbCr-to-RGB conversion step (although you should still see\nsignificant JPEG speedup from the other changes).\n\nPlease note that STBI_JPEG_OLD is a temporary feature; it will be\nremoved in future versions of the library. It is only intended for\nnear-term back-compatibility use.\n\n\nLatest revision history:\n2.13 (2016-12-04) experimental 16-bit API, only for PNG so far; fixes\n2.12 (2016-04-02) fix typo in 2.11 PSD fix that caused crashes\n2.11 (2016-04-02) 16-bit PNGS; enable SSE2 in non-gcc x64\nRGB-format JPEG; remove white matting in PSD;\nallocate large structures on the stack;\ncorrect channel count for PNG & BMP\n2.10 (2016-01-22) avoid warning introduced in 2.09\n2.09 (2016-01-16) 16-bit TGA; comments in PNM files; STBI_REALLOC_SIZED\n2.08 (2015-09-13) fix to 2.07 cleanup, reading RGB PSD as RGBA\n2.07 (2015-09-13) partial animated GIF support\nlimited 16-bit PSD support\nminor bugs, code cleanup, and compiler warnings\n\nSee end of file for full revision history.\n\n\n============================ Contributors =========================\n\nImage formats Extensions, features\nSean Barrett (jpeg, png, bmp) Jetro Lauha (stbi_info)\nNicolas Schulz (hdr, psd) Martin \"SpartanJ\" Golini (stbi_info)\nJonathan Dummer (tga) James \"moose2000\" Brown (iPhone PNG)\nJean-Marc Lienher (gif) Ben \"Disch\" Wenger (io callbacks)\nTom Seddon (pic) Omar Cornut (1/2/4-bit PNG)\nThatcher Ulrich (psd) Nicolas Guillemot (vertical flip)\nKen Miller (pgm, ppm) Richard Mitton (16-bit PSD)\ngithub:urraka (animated gif) Junggon Kim (PNM comments)\nDaniel Gibson (16-bit TGA)\nsocks-the-fox (16-bit TGA)\nOptimizations & bugfixes\nFabian \"ryg\" Giesen\nArseny Kapoulkine\n\nBug & warning fixes\nMarc LeBlanc David Woo Guillaume George Martins Mozeiko\nChristpher Lloyd Martin Golini Jerry Jansson Joseph Thomson\nDave Moore Roy Eltham Hayaki Saito Phil Jordan\nWon Chun Luke Graham Johan Duparc Nathan Reed\nthe Horde3D community Thomas Ruf Ronny Chevalier Nick Verigakis\nJanez Zemva John Bartholomew Michal Cichon github:svdijk\nJonathan Blow Ken Hamada Tero Hanninen Baldur Karlsson\nLaurent Gomila Cort Stratton Sergio Gonzalez github:romigrou\nAruelien Pocheville Thibault Reuille Cass Everitt Matthew Gregan\nRyamond Barbiero Paul Du Bois Engin Manap github:snagar\nMichaelangel007@github Oriol Ferrer Mesia Dale Weiler github:Zelex\nPhilipp Wiesemann Josh Tobin github:rlyeh github:grim210@github\nBlazej Dariusz Roszkowski github:sammyhw\n\n\nLICENSE\n\nThis software is dual-licensed to the public domain and under the following\nlicense: you are granted a perpetual, irrevocable license to copy, modify,\npublish, and distribute this file as you see fit.\n\n*/\n\n#ifndef STBI_INCLUDE_STB_IMAGE_H\n#define STBI_INCLUDE_STB_IMAGE_H\n\n// DOCUMENTATION\n//\n// Limitations:\n// - no 16-bit-per-channel PNG\n// - no 12-bit-per-channel JPEG\n// - no JPEGs with arithmetic coding\n// - no 1-bit BMP\n// - GIF always returns *comp=4\n//\n// Basic usage (see HDR discussion below for HDR usage):\n// int x,y,n;\n// unsigned char *data = stbi_load(filename, &x, &y, &n, 0);\n// // ... process data if not NULL ...\n// // ... x = width, y = height, n = # 8-bit components per pixel ...\n// // ... replace '0' with '1'..'4' to force that many components per pixel\n// // ... but 'n' will always be the number that it would have been if you said 0\n// stbi_image_free(data)\n//\n// Standard parameters:\n// int *x -- outputs image width in pixels\n// int *y -- outputs image height in pixels\n// int *channels_in_file -- outputs # of image components in image file\n// int desired_channels -- if non-zero, # of image components requested in result\n//\n// The return value from an image loader is an 'unsigned char *' which points\n// to the pixel data, or NULL on an allocation failure or if the image is\n// corrupt or invalid.

Nevertheless, it's important\n// to keep in mind that from the standpoint of you, a client of this library,\n// all you care about is #1 and #3, and stb libraries do not emphasize #3 above all.\n//\n// Some secondary priorities arise directly from the first two, some of which\n// make more explicit reasons why performance can't be emphasized.\n//\n// - Portable (\"ease of use\")\n// - Small footprint (\"easy to maintain\")\n// - No dependencies (\"ease of use\")\n//\n// ===========================================================================\n//\n// I/O callbacks\n//\n// I/O callbacks allow you to read from arbitrary sources, like packaged\n// files or some other source. Data read from callbacks are processed\n// through a small internal buffer (currently 128 bytes) to try to reduce\n// overhead.\n//\n// The three functions you must define are \"read\" (reads some bytes of data),\n// \"skip\" (skips some bytes of data), \"eof\" (reports if the stream is at the end).\n//\n// ===========================================================================\n//\n// SIMD support\n//\n// The JPEG decoder will try to automatically use SIMD kernels on x86 when\n// supported by the compiler. For ARM Neon support, you must explicitly\n// request it.\n//\n// (The old do-it-yourself SIMD API is no longer supported in the current\n// code.)\n//\n// On x86, SSE2 will automatically be used when available based on a run-time\n// test; if not, the generic C versions are used as a fall-back. On ARM targets,\n// the typical path is to have separate builds for NEON and non-NEON devices\n// (at least this is true for iOS and Android). Therefore, the NEON support is\n// toggled by a build flag: define STBI_NEON to get NEON loops.\n//\n// The output of the JPEG decoder is slightly different from versions where\n// SIMD support was introduced (that is, for versions before 1.49). The\n// difference is only +-1 in the 8-bit RGB channels, and only on a small\n// fraction of pixels. You can force the pre-1.49 behavior by defining\n// STBI_JPEG_OLD, but this will disable some of the SIMD decoding path\n// and hence cost some performance.\n//\n// If for some reason you do not want to use any of SIMD code, or if\n// you have issues compiling it, you can disable it entirely by\n// defining STBI_NO_SIMD.\n//\n// ===========================================================================\n//\n// HDR image support (disable by defining STBI_NO_HDR)\n//\n// stb_image now supports loading HDR images in general, and currently\n// the Radiance .HDR file format, although the support is provided\n// generically. You can still load any file through the existing interface;\n// if you attempt to load an HDR file, it will be automatically remapped to\n// LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;\n// both of these constants can be reconfigured through this interface:\n//\n// stbi_hdr_to_ldr_gamma(2.2f);\n// stbi_hdr_to_ldr_scale(1.0f);\n//\n// (note, do not use _inverse_ constants; stbi_image will invert them\n// appropriately).\n//\n// Additionally, there is a new, parallel interface for loading files as\n// (linear) floats to preserve the full dynamic range:\n//\n// float *data = stbi_loadf(filename, &x, &y, &n, 0);\n//\n// If you load LDR images through this interface, those images will\n// be promoted to floating point values, run through the inverse of\n// constants corresponding to the above:\n//\n// stbi_ldr_to_hdr_scale(1.0f);\n// stbi_ldr_to_hdr_gamma(2.2f);\n//\n// Finally, given a filename (or an open file or memory block--see header\n// file for details) containing image data, you can query for the \"most\n// appropriate\" interface to use (that is, whether the image is HDR or\n// not), using:\n//\n// stbi_is_hdr(char *filename);\n//\n// ===========================================================================\n//\n// iPhone PNG support:\n//\n// By default we convert iphone-formatted PNGs back to RGB, even though\n// they are internally encoded differently. You can disable this conversion\n// by by calling stbi_convert_iphone_png_to_rgb(0), in which case\n// you will always just get the native iphone \"format\" through (which\n// is BGR stored in RGB).\n//\n// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per\n// pixel to remove any premultiplied alpha *only* if the image file explicitly\n// says there's premultiplied data (currently only happens in iPhone images,\n// and only if iPhone convert-to-rgb processing is on).\n//\n\n\n#ifndef STBI_NO_STDIO\n#include \n#endif // STBI_NO_STDIO\n\n#define STBI_VERSION 1\n\nenum\n{\n STBI_default = 0, // only used for req_comp\n\n STBI_grey = 1,\n STBI_grey_alpha = 2,\n STBI_rgb = 3,\n STBI_rgb_alpha = 4\n};\n\ntypedef unsigned char stbi_uc;\ntypedef unsigned short stbi_us;\n\n#ifdef __cplusplus\nextern \"C\" {\n#endif\n\n#ifdef STB_IMAGE_STATIC\n#define STBIDEF static\n#else\n#define STBIDEF extern\n#endif\n\n //////////////////////////////////////////////////////////////////////////////\n //\n // PRIMARY API -

The pixel data consists of *y scanlines of *x pixels,\n// with each pixel consisting of N interleaved 8-bit components; the first\n// pixel pointed to is top-left-most in the image. There is no padding between\n// image scanlines or between pixels, regardless of format. The number of\n// components N is 'req_comp' if req_comp is non-zero, or *comp otherwise.\n// If req_comp is non-zero, *comp has the number of components that _would_\n// have been output otherwise.

This is\n * a very useful and long desired include file which contains several\n * very precise definitions for integer scalar types that is\n * critically important for making portable several classes of\n * applications including cryptography, hashing, variable length\n * integer libraries and so on. But for most developers its likely\n * useful just for programming sanity.\n *\n * The problem is that some compiler vendors chose to ignore the C99\n * standard and some older compilers have no opportunity to be updated.\n * Because of this situation, simply including stdint.h in your code\n * makes it unportable.\n *\n * So that's what this file is all about. Its an attempt to build a\n * single universal include file that works on as many platforms as\n * possible to deliver what stdint.h is supposed to. Even compilers\n * that already come with stdint.h can use this file instead without\n * any loss of functionality. A few things that should be noted about\n * this file:\n *\n * 1) It is not guaranteed to be portable and/or present an identical\n * interface on all platforms. The extreme variability of the\n * ANSI C standard makes this an impossibility right from the\n * very get go. Its really only meant to be useful for the vast\n * majority of platforms that possess the capability of\n * implementing usefully and precisely defined, standard sized\n * integer scalars. Systems which are not intrinsically 2s\n * complement may produce invalid constants.\n *\n * 2) There is an unavoidable use of non-reserved symbols.\n *\n * 3) Other standard include files are invoked.\n *\n * 4) This file may come in conflict with future platforms that do\n * include stdint.h. The hope is that one or the other can be\n * used with no real difference.\n *\n * 5) In the current version, if your platform can't represent\n * int32_t, int16_t and int8_t, it just dumps out with a compiler\n * error.\n *\n * 6) 64 bit integers may or may not be defined. Test for their\n * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.\n * Note that this is different from the C99 specification which\n * requires the existence of 64 bit support in the compiler. If\n * this is not defined for your platform, yet it is capable of\n * dealing with 64 bits then it is because this file has not yet\n * been extended to cover all of your system's capabilities.\n *\n * 7) (u)intptr_t may or may not be defined. Test for its presence\n * with the test: #ifdef PTRDIFF_MAX. If this is not defined\n * for your platform, then it is because this file has not yet\n * been extended to cover all of your system's capabilities, not\n * because its optional.\n *\n * 8) The following might not been defined even if your platform is\n * capable of defining it:\n *\n * WCHAR_MIN\n * WCHAR_MAX\n * (u)int64_t\n * PTRDIFF_MIN\n * PTRDIFF_MAX\n * (u)intptr_t\n *\n * 9) The following have not been defined:\n *\n * WINT_MIN\n * WINT_MAX\n *\n * 10) The criteria for defining (u)int_least(*)_t isn't clear,\n * except for systems which don't have a type that precisely\n * defined 8, 16, or 32 bit types (which this include file does\n * not support anyways). Default definitions have been given.\n *\n * 11) The criteria for defining (u)int_fast(*)_t isn't something I\n * would trust to any particular compiler vendor or the ANSI C\n * committee. It is well known that \"compatible systems\" are\n * commonly created that have very different performance\n * characteristics from the systems they are compatible with,\n * especially those whose vendors make both the compiler and the\n * system. Default definitions have been given, but its strongly\n * recommended that users never use these definitions for any\n * reason (they do *NOT* deliver any serious guarantee of\n * improved performance -- not in this file, nor any vendor's\n * stdint.h).\n *\n * 12) The following macros:\n *\n * PRINTF_INTMAX_MODIFIER\n * PRINTF_INT64_MODIFIER\n * PRINTF_INT32_MODIFIER\n * PRINTF_INT16_MODIFIER\n * PRINTF_LEAST64_MODIFIER\n * PRINTF_LEAST32_MODIFIER\n * PRINTF_LEAST16_MODIFIER\n * PRINTF_INTPTR_MODIFIER\n *\n * are strings which have been defined as the modifiers required\n * for the \"d\", \"u\" and \"x\" printf formats to correctly output\n * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,\n * (u)least32_t, (u)least16_t and (u)intptr_t types respectively.\n * PRINTF_INTPTR_MODIFIER is not defined for some systems which\n * provide their own stdint.h. PRINTF_INT64_MODIFIER is not\n * defined if INT64_MAX is not defined. These are an extension\n * beyond what C99 specifies must be in stdint.h.\n *\n * In addition, the following macros are defined:\n *\n * PRINTF_INTMAX_HEX_WIDTH\n * PRINTF_INT64_HEX_WIDTH\n * PRINTF_INT32_HEX_WIDTH\n * PRINTF_INT16_HEX_WIDTH\n * PRINTF_INT8_HEX_WIDTH\n * PRINTF_INTMAX_DEC_WIDTH\n * PRINTF_INT64_DEC_WIDTH\n * PRINTF_INT32_DEC_WIDTH\n * PRINTF_INT16_DEC_WIDTH\n * PRINTF_UINT8_DEC_WIDTH\n * PRINTF_UINTMAX_DEC_WIDTH\n * PRINTF_UINT64_DEC_WIDTH\n * PRINTF_UINT32_DEC_WIDTH\n * PRINTF_UINT16_DEC_WIDTH\n * PRINTF_UINT8_DEC_WIDTH\n *\n * Which specifies the maximum number of characters required to\n * print the number of that type in either hexadecimal or decimal.\n * These are an extension beyond what C99 specifies must be in\n * stdint.h.\n *\n * Compilers tested (all with 0 warnings at their highest respective\n * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32\n * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio\n * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3\n *\n * This file should be considered a work in progress. Suggestions for\n * improvements, especially those which increase coverage are strongly\n * encouraged.\n *\n * Acknowledgements\n *\n * The following people have made significant contributions to the\n * development and testing of this file:\n *\n * Chris Howie\n * John Steele Scott\n * Dave Thorup\n * John Dill\n * Florian Wobbe\n * Christopher Sean Morrison\n * Mikkel Fahnoe Jorgensen\n *\n */\n\n#include \n#include \n#include \n\n/*\n * For gcc with _STDINT_H, fill in the PRINTF_INT*_MODIFIER macros, and\n * do nothing else.

They inform client applications of properties of the\n * corresponding face.\n *\n * @values:\n * FT_FACE_FLAG_SCALABLE ::\n * The face contains outline glyphs. Note that a face can contain\n * bitmap strikes also, i.e., a face can have both this flag and\n * @FT_FACE_FLAG_FIXED_SIZES set.\n *\n * FT_FACE_FLAG_FIXED_SIZES ::\n * The face contains bitmap strikes. See also the `num_fixed_sizes`\n * and `available_sizes` fields of @FT_FaceRec.\n *\n * FT_FACE_FLAG_FIXED_WIDTH ::\n * The face contains fixed-width characters (like Courier, Lucida,\n * MonoType, etc.).\n *\n * FT_FACE_FLAG_SFNT ::\n * The face uses the SFNT storage scheme. For now, this means TrueType\n * and OpenType.\n *\n * FT_FACE_FLAG_HORIZONTAL ::\n * The face contains horizontal glyph metrics. This should be set for\n * all common formats.\n *\n * FT_FACE_FLAG_VERTICAL ::\n * The face contains vertical glyph metrics. This is only available in\n * some formats, not all of them.\n *\n * FT_FACE_FLAG_KERNING ::\n * The face contains kerning information. If set, the kerning distance\n * can be retrieved using the function @FT_Get_Kerning. Otherwise the\n * function always return the vector (0,0). Note that FreeType doesn't\n * handle kerning data from the SFNT 'GPOS' table (as present in many\n * OpenType fonts).\n *\n * FT_FACE_FLAG_FAST_GLYPHS ::\n * THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT.\n *\n * FT_FACE_FLAG_MULTIPLE_MASTERS ::\n * The face contains multiple masters and is capable of interpolating\n * between them. Supported formats are Adobe MM, TrueType GX, and\n * OpenType variation fonts.\n *\n * See section @multiple_masters for API details.\n *\n * FT_FACE_FLAG_GLYPH_NAMES ::\n * The face contains glyph names, which can be retrieved using\n * @FT_Get_Glyph_Name. Note that some TrueType fonts contain broken\n * glyph name tables. Use the function @FT_Has_PS_Glyph_Names when\n * needed.\n *\n * FT_FACE_FLAG_EXTERNAL_STREAM ::\n * Used internally by FreeType to indicate that a face's stream was\n * provided by the client application and should not be destroyed when\n * @FT_Done_Face is called. Don't read or test this flag.\n *\n * FT_FACE_FLAG_HINTER ::\n * The font driver has a hinting machine of its own. For example, with\n * TrueType fonts, it makes sense to use data from the SFNT 'gasp'\n * table only if the native TrueType hinting engine (with the bytecode\n * interpreter) is available and active.\n *\n * FT_FACE_FLAG_CID_KEYED ::\n * The face is CID-keyed. In that case, the face is not accessed by\n * glyph indices but by CID values. For subsetted CID-keyed fonts this\n * has the consequence that not all index values are a valid argument\n * to @FT_Load_Glyph. Only the CID values for which corresponding\n * glyphs in the subsetted font exist make `FT_Load_Glyph` return\n * successfully; in all other cases you get an\n * `FT_Err_Invalid_Argument` error.\n *\n * Note that CID-keyed fonts that are in an SFNT wrapper (this is, all\n * OpenType/CFF fonts) don't have this flag set since the glyphs are\n * accessed in the normal way (using contiguous indices); the\n * 'CID-ness' isn't visible to the application.\n *\n * FT_FACE_FLAG_TRICKY ::\n * The face is 'tricky', this is, it always needs the font format's\n * native hinting engine to get a reasonable result. A typical example\n * is the old Chinese font `mingli.ttf` (but not `mingliu.ttc`) that\n * uses TrueType bytecode instructions to move and scale all of its\n * subglyphs.\n *\n * It is not possible to auto-hint such fonts using\n * @FT_LOAD_FORCE_AUTOHINT; it will also ignore @FT_LOAD_NO_HINTING.\n * You have to set both @FT_LOAD_NO_HINTING and @FT_LOAD_NO_AUTOHINT to\n * really disable hinting; however, you probably never want this except\n * for demonstration purposes.\n *\n * Currently, there are about a dozen TrueType fonts in the list of\n * tricky fonts; they are hard-coded in file `ttobjs.c`.\n *\n * FT_FACE_FLAG_COLOR ::\n * [Since 2.5.1] The face has color glyph tables. See @FT_LOAD_COLOR\n * for more information.\n *\n * FT_FACE_FLAG_VARIATION ::\n * [Since 2.9] Set if the current face (or named instance) has been\n * altered with @FT_Set_MM_Design_Coordinates,\n * @FT_Set_Var_Design_Coordinates, or @FT_Set_Var_Blend_Coordinates.\n * This flag is unset by a call to @FT_Set_Named_Instance.\n */\n#define FT_FACE_FLAG_SCALABLE ( 1L << 0 )\n#define FT_FACE_FLAG_FIXED_SIZES ( 1L << 1 )\n#define FT_FACE_FLAG_FIXED_WIDTH ( 1L << 2 )\n#define FT_FACE_FLAG_SFNT ( 1L << 3 )\n#define FT_FACE_FLAG_HORIZONTAL ( 1L << 4 )\n#define FT_FACE_FLAG_VERTICAL ( 1L << 5 )\n#define FT_FACE_FLAG_KERNING ( 1L << 6 )\n#define FT_FACE_FLAG_FAST_GLYPHS ( 1L << 7 )\n#define FT_FACE_FLAG_MULTIPLE_MASTERS ( 1L << 8 )\n#define FT_FACE_FLAG_GLYPH_NAMES ( 1L << 9 )\n#define FT_FACE_FLAG_EXTERNAL_STREAM ( 1L << 10 )\n#define FT_FACE_FLAG_HINTER ( 1L << 11 )\n#define FT_FACE_FLAG_CID_KEYED ( 1L << 12 )\n#define FT_FACE_FLAG_TRICKY ( 1L << 13 )\n#define FT_FACE_FLAG_COLOR ( 1L << 14 )\n#define FT_FACE_FLAG_VARIATION ( 1L << 15 )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_HAS_HORIZONTAL\n *\n * @description:\n * A macro that returns true whenever a face object contains horizontal\n * metrics (this is true for all font formats though).\n *\n * @also:\n * @FT_HAS_VERTICAL can be used to check for vertical metrics.\n *\n */\n#define FT_HAS_HORIZONTAL( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_HORIZONTAL ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_HAS_VERTICAL\n *\n * @description:\n * A macro that returns true whenever a face object contains real\n * vertical metrics (and not only synthesized ones).\n *\n */\n#define FT_HAS_VERTICAL( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_VERTICAL ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_HAS_KERNING\n *\n * @description:\n * A macro that returns true whenever a face object contains kerning data\n * that can be accessed with @FT_Get_Kerning.\n *\n */\n#define FT_HAS_KERNING( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_KERNING ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_IS_SCALABLE\n *\n * @description:\n * A macro that returns true whenever a face object contains a scalable\n * font face (true for TrueType, Type~1, Type~42, CID, OpenType/CFF, and\n * PFR font formats).\n *\n */\n#define FT_IS_SCALABLE( face ) \\\n ( !!( (face)->face_flags & FT_FACE_FLAG_SCALABLE ) )\n\n\n /**************************************************************************\n *\n * @macro:\n * FT_IS_SFNT\n *\n * @description:\n * A macro that returns true whenever a face object contains a font whose\n * format is based on the SFNT storage scheme.

This implies\n * the following scheme:\n *\n * First, available or installed font faces are uniquely identified by\n * @FTC_FaceID values, provided to the cache by the client. Note that\n * the cache only stores and compares these values, and doesn't try to\n * interpret them in any way.\n *\n * Second, the cache calls, only when needed, a client-provided function\n * to convert an @FTC_FaceID into a new @FT_Face object. The latter is\n * then completely managed by the cache, including its termination\n * through @FT_Done_Face. To monitor termination of face objects, the\n * finalizer callback in the `generic` field of the @FT_Face object can\n * be used, which might also be used to store the @FTC_FaceID of the\n * face.\n *\n * Clients are free to map face IDs to anything else. The most simple\n * usage is to associate them to a (pathname,face_index) pair that is\n * used to call @FT_New_Face. However, more complex schemes are also\n * possible.\n *\n * Note that for the cache to work correctly, the face ID values must be\n * **persistent**, which means that the contents they point to should not\n * change at runtime, or that their value should not become invalid.\n *\n * If this is unavoidable (e.g., when a font is uninstalled at runtime),\n * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let\n * the cache get rid of any references to the old @FTC_FaceID it may keep\n * internally. Failure to do so will lead to incorrect behaviour or even\n * crashes.\n *\n * To use the cache, start with calling @FTC_Manager_New to create a new\n * @FTC_Manager object, which models a single cache instance. You can\n * then look up @FT_Face and @FT_Size objects with\n * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.\n *\n * If you want to use the charmap caching, call @FTC_CMapCache_New, then\n * later use @FTC_CMapCache_Lookup to perform the equivalent of\n * @FT_Get_Char_Index, only much faster.\n *\n * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then\n * later use @FTC_ImageCache_Lookup to retrieve the corresponding\n * @FT_Glyph objects from the cache.\n *\n * If you need lots of small bitmaps, it is much more memory efficient to\n * call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This\n * returns @FTC_SBitRec structures, which are used to store small bitmaps\n * directly. (A small bitmap is one whose metrics and dimensions all fit\n * into 8-bit integers).\n *\n * We hope to also provide a kerning cache in the near future.\n *\n *\n * @order:\n * FTC_Manager\n * FTC_FaceID\n * FTC_Face_Requester\n *\n * FTC_Manager_New\n * FTC_Manager_Reset\n * FTC_Manager_Done\n * FTC_Manager_LookupFace\n * FTC_Manager_LookupSize\n * FTC_Manager_RemoveFaceID\n *\n * FTC_Node\n * FTC_Node_Unref\n *\n * FTC_ImageCache\n * FTC_ImageCache_New\n * FTC_ImageCache_Lookup\n *\n * FTC_SBit\n * FTC_SBitCache\n * FTC_SBitCache_New\n * FTC_SBitCache_Lookup\n *\n * FTC_CMapCache\n * FTC_CMapCache_New\n * FTC_CMapCache_Lookup\n *\n *************************************************************************/\n\n\n /*************************************************************************/\n /*************************************************************************/\n /*************************************************************************/\n /***** *****/\n /***** BASIC TYPE DEFINITIONS *****/\n /***** *****/\n /*************************************************************************/\n /*************************************************************************/\n /*************************************************************************/\n\n\n /**************************************************************************\n *\n * @type:\n * FTC_FaceID\n *\n * @description:\n * An opaque pointer type that is used to identity face objects.

Sometimes the\n * vertical stems may be only partially black. In this context,\n * 'antialiasing' means that stems are not positioned exactly on pixel\n * borders, causing a fuzzy appearance.\n *\n * There are two principles behind this approach.\n *\n * 1) No hinting in the horizontal direction: Unlike 'superhinted'\n * TrueType, which changes glyph widths to accommodate regular\n * inter-glyph spacing, Adobe's approach is 'faithful to the design' in\n * representing both the glyph width and the inter-glyph spacing designed\n * for the font. This makes the screen display as close as it can be to\n * the result one would get with infinite resolution, while preserving\n * what is considered the key characteristics of each glyph. Note that\n * the distances between unhinted and grid-fitted positions at small\n * sizes are comparable to kerning values and thus would be noticeable\n * (and distracting) while reading if hinting were applied.\n *\n * One of the reasons to not hint horizontally is antialiasing for LCD\n * screens: The pixel geometry of modern displays supplies three vertical\n * subpixels as the eye moves horizontally across each visible pixel. On\n * devices where we can be certain this characteristic is present a\n * rasterizer can take advantage of the subpixels to add increments of\n * weight. In Western writing systems this turns out to be the more\n * critical direction anyway; the weights and spacing of vertical stems\n * (see above) are central to Armenian, Cyrillic, Greek, and Latin type\n * designs. Even when the rasterizer uses greyscale antialiasing instead\n * of color (a necessary compromise when one doesn't know the screen\n * characteristics), the unhinted vertical features preserve the design's\n * weight and spacing much better than aliased type would.\n *\n * 2) Alignment in the vertical direction: Weights and spacing along the\n * y~axis are less critical; what is much more important is the visual\n * alignment of related features (like cap-height and x-height). The\n * sense of alignment for these is enhanced by the sharpness of grid-fit\n * edges, while the cruder vertical resolution (full pixels instead of\n * 1/3 pixels) is less of a problem.\n *\n * On the technical side, horizontal alignment zones for ascender,\n * x-height, and other important height values (traditionally called\n * 'blue zones') as defined in the font are positioned independently,\n * each being rounded to the nearest pixel edge, taking care of overshoot\n * suppression at small sizes, stem darkening, and scaling.\n *\n * Hstems (this is, hint values defined in the font to help align\n * horizontal features) that fall within a blue zone are said to be\n * 'captured' and are aligned to that zone. Uncaptured stems are moved\n * in one of four ways, top edge up or down, bottom edge up or down.\n * Unless there are conflicting hstems, the smallest movement is taken to\n * minimize distortion.\n *\n */\n\n\n /**************************************************************************\n *\n * @section:\n * pcf_driver\n *\n * @title:\n * The PCF driver\n *\n * @abstract:\n * Controlling the PCF driver module.\n *\n * @description:\n * While FreeType's PCF driver doesn't expose API functions by itself, it\n * is possible to control its behaviour with @FT_Property_Set and\n * @FT_Property_Get.

The following lists the available properties\n * together with the necessary macros and structures.\n *\n * The TrueType driver's module name is 'truetype'.\n *\n * A single property @interpreter-version is available, as documented in\n * the @properties section.\n *\n * We start with a list of definitions, kindly provided by Greg\n * Hitchcock.\n *\n * _Bi-Level Rendering_\n *\n * Monochromatic rendering, exclusively used in the early days of\n * TrueType by both Apple and Microsoft. Microsoft's GDI interface\n * supported hinting of the right-side bearing point, such that the\n * advance width could be non-linear. Most often this was done to\n * achieve some level of glyph symmetry. To enable reasonable\n * performance (e.g., not having to run hinting on all glyphs just to get\n * the widths) there was a bit in the head table indicating if the side\n * bearing was hinted, and additional tables, 'hdmx' and 'LTSH', to cache\n * hinting widths across multiple sizes and device aspect ratios.\n *\n * _Font Smoothing_\n *\n * Microsoft's GDI implementation of anti-aliasing. Not traditional\n * anti-aliasing as the outlines were hinted before the sampling. The\n * widths matched the bi-level rendering.\n *\n * _ClearType Rendering_\n *\n * Technique that uses physical subpixels to improve rendering on LCD\n * (and other) displays. Because of the higher resolution, many methods\n * of improving symmetry in glyphs through hinting the right-side bearing\n * were no longer necessary. This lead to what GDI calls 'natural\n * widths' ClearType, see\n * http://rastertragedy.com/RTRCh4.htm#Sec21. Since hinting\n * has extra resolution, most non-linearity went away, but it is still\n * possible for hints to change the advance widths in this mode.\n *\n * _ClearType Compatible Widths_\n *\n * One of the earliest challenges with ClearType was allowing the\n * implementation in GDI to be selected without requiring all UI and\n * documents to reflow. To address this, a compatible method of\n * rendering ClearType was added where the font hints are executed once\n * to determine the width in bi-level rendering, and then re-run in\n * ClearType, with the difference in widths being absorbed in the font\n * hints for ClearType (mostly in the white space of hints); see\n * http://rastertragedy.com/RTRCh4.htm#Sec20. Somewhat by\n * definition, compatible width ClearType allows for non-linear widths,\n * but only when the bi-level version has non-linear widths.\n *\n * _ClearType Subpixel Positioning_\n *\n * One of the nice benefits of ClearType is the ability to more crisply\n * display fractional widths; unfortunately, the GDI model of integer\n * bitmaps did not support this. However, the WPF and Direct Write\n * frameworks do support fractional widths. DWrite calls this 'natural\n * mode', not to be confused with GDI's 'natural widths'. Subpixel\n * positioning, in the current implementation of Direct Write,\n * unfortunately does not support hinted advance widths, see\n * http://rastertragedy.com/RTRCh4.htm#Sec22. Note that the\n * TrueType interpreter fully allows the advance width to be adjusted in\n * this mode, just the DWrite client will ignore those changes.\n *\n * _ClearType Backward Compatibility_\n *\n * This is a set of exceptions made in the TrueType interpreter to\n * minimize hinting techniques that were problematic with the extra\n * resolution of ClearType; see\n * http://rastertragedy.com/RTRCh4.htm#Sec1 and\n * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.\n * This technique is not to be confused with ClearType compatible widths.\n * ClearType backward compatibility has no direct impact on changing\n * advance widths, but there might be an indirect impact on disabling\n * some deltas. This could be worked around in backward compatibility\n * mode.\n *\n * _Native ClearType Mode_\n *\n * (Not to be confused with 'natural widths'.) This mode removes all the\n * exceptions in the TrueType interpreter when running with ClearType.\n * Any issues on widths would still apply, though.\n *\n */\n\n\n /**************************************************************************\n *\n * @section:\n * properties\n *\n * @title:\n * Driver properties\n *\n * @abstract:\n * Controlling driver modules.\n *\n * @description:\n * Driver modules can be controlled by setting and unsetting properties,\n * using the functions @FT_Property_Set and @FT_Property_Get.

'e' is the error\n * code identifier (e.g., `Invalid_Argument`), 'v' is the error's\n * numerical value, and 's' is the corresponding error string.\n *\n * ```\n * FT_ERROR_END_LIST\n * ```\n *\n * This macro ends the list.\n *\n * Additionally, you have to undefine `FTERRORS_H_` before #including\n * this file.\n *\n * Here is a simple example.\n *\n * ```\n * #undef FTERRORS_H_\n * #define FT_ERRORDEF( e, v, s ) { e, s },\n * #define FT_ERROR_START_LIST {\n * #define FT_ERROR_END_LIST { 0, NULL } };\n *\n * const struct\n * {\n * int err_code;\n * const char* err_msg;\n * } ft_errors[] =\n *\n * #include FT_ERRORS_H\n * ```\n *\n * An alternative to using an array is a switch statement.\n *\n * ```\n * #undef FTERRORS_H_\n * #define FT_ERROR_START_LIST switch ( error_code ) {\n * #define FT_ERRORDEF( e, v, s ) case v: return s;\n * #define FT_ERROR_END_LIST }\n * ```\n *\n * If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should\n * be replaced with `FT_ERROR_BASE(error_code)` in the last example.\n */\n\n /* */\n\n /* In previous FreeType versions we used `__FTERRORS_H__`.

These technologies are\n * controlled differently and API described below, although always\n * available, performs its function when appropriate method is enabled\n * and does nothing otherwise.\n *\n * ClearType-style LCD rendering exploits the color-striped structure of\n * LCD pixels, increasing the available resolution in the direction of\n * the stripe (usually horizontal RGB) by a factor of~3. Using the\n * subpixels coverages unfiltered can create severe color fringes\n * especially when rendering thin features. Indeed, to produce\n * black-on-white text, the nearby color subpixels must be dimmed\n * equally.\n *\n * A good 5-tap FIR filter should be applied to subpixel coverages\n * regardless of pixel boundaries and should have these properties:\n *\n * 1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid\n * any shifts in appearance.\n *\n * 2. It should be color-balanced, meaning a~+ b~=~c, to reduce color\n * fringes by distributing the computed coverage for one subpixel to\n * all subpixels equally.\n *\n * 3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain\n * overall brightness.\n *\n * Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less\n * forgiving of non-ideal gamma curves of a screen (and viewing angles),\n * beveled filters are fuzzier but more tolerant.\n *\n * Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights\n * API to specify a low-pass filter, which is then applied to\n * subpixel-rendered bitmaps generated through @FT_Render_Glyph.\n *\n * Harmony LCD rendering is suitable to panels with any regular subpixel\n * structure, not just monitors with 3 color striped subpixels, as long\n * as the color subpixels have fixed positions relative to the pixel\n * center. In this case, each color channel is then rendered separately\n * after shifting the outline opposite to the subpixel shift so that the\n * coverage maps are aligned. This method is immune to color fringes\n * because the shifts do not change integral coverage.\n *\n * The subpixel geometry must be specified by xy-coordinates for each\n * subpixel. By convention they may come in the RGB order: {{-1/3, 0},\n * {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},\n * {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.\n *\n * Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.\n * If one follows the RGB order convention, the same order applies to the\n * resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps. Note,\n * however, that the coordinate frame for the latter must be rotated\n * clockwise. Harmony with default LCD geometry is equivalent to\n * ClearType with light filter.\n *\n * As a result of ClearType filtering or Harmony rendering, the\n * dimensions of LCD bitmaps can be either wider or taller than the\n * dimensions of the corresponding outline with regard to the pixel grid.\n * For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to\n * the left, and 2~subpixels to the right. The bitmap offset values are\n * adjusted accordingly, so clients shouldn't need to modify their layout\n * and glyph positioning code when enabling the filter.\n *\n * The ClearType and Harmony rendering is applicable to glyph bitmaps\n * rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and\n * @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V\n * is specified. This API does not control @FT_Outline_Render and\n * @FT_Outline_Get_Bitmap.\n *\n * The described algorithms can completely remove color artefacts when\n * combined with gamma-corrected alpha blending in linear space. Each of\n * the 3~alpha values (subpixels) must by independently used to blend one\n * color channel. That is, red alpha blends the red channel of the text\n * color with the red channel of the background pixel.\n */\n\n\n /**************************************************************************\n *\n * @enum:\n * FT_LcdFilter\n *\n * @description:\n * A list of values to identify various types of LCD filters.\n *\n * @values:\n * FT_LCD_FILTER_NONE ::\n * Do not perform filtering.

However, we might be\n * interested in introducing more complex and powerful algorithms in the\n * future, like the one described in the John D. Hobby paper, which\n * unfortunately requires a lot more horsepower.\n *\n * Because a sufficiently sophisticated font management system would\n * typically implement an LRU cache of opened face objects to reduce memory\n * usage, it is a good idea to be able to avoid recomputing global hints\n * every time the same face is re-opened.\n *\n * We thus provide the ability to cache global hints outside of the face\n * object, in order to speed up font re-opening time. Of course, this\n * feature is purely optional, so most client programs won't even notice\n * it.\n *\n * I initially thought that it would be a good idea to cache the glyph\n * hints too. However, my general idea now is that if you really need to\n * cache these too, you are simply in need of a new font format, where all\n * this information could be stored within the font file and decoded on the\n * fly.\n *\n */\n\n\n#include \n#include FT_FREETYPE_H\n\n\nFT_BEGIN_HEADER\n\n\n typedef struct FT_AutoHinterRec_ *FT_AutoHinter;\n\n\n /**************************************************************************\n *\n * @functype:\n * FT_AutoHinter_GlobalGetFunc\n *\n * @description:\n * Retrieve the global hints computed for a given face object.

\n *\n * \\section intro Introduction\n *\n * Welcome to the irrKlang API documentation. This page should give you a short overview \n * over irrKlang, the high level audio library. \n * In this documentation files you'll find any information you'll need to develop applications with\n * irrKlang using C++. If you are looking for a tutorial on how to start, you'll\n * find some on the homepage of irrKlang at\n * http://www.ambiera.com/irrklang\n * or inside the SDK in the directory \\examples.\n *\n * The irrKlang library is intended to be an easy-to-use 3d and 2d sound engine, so\n * this documentation is an important part of it. If you have any questions or\n * suggestions, please take a look into the ambiera.com forum or just send a mail.\n *\n *

\n *\n *\n *\n * \\section tipsandtricks Tips and Tricks\n *\n * This section lists a few tips you might consider when implementing the sound part of your application\n * using irrKlang:\n *\n *
    \n *
  • If you can choose which audio file format is the primary one for your application,\n *\t\t\t\t\t use .OGG files, instead of for example .MP3 files. irrKlang uses a lot less memory\n * and CPU power when playing .OGGs.
    • \n *
  • To keep your application simple, each time you play a sound, you can use for example\n * play2D(\"filename.mp3\") and let irrKlang handle the rest. There is no need to implement\n * a preloading/caching/file management system for the audio playback. irrKlang will handle\n * all this by itself and will never load a file twice.
    • \n *
  • irrKlang is crashing in your application? This should not happen, irrKlang is pretty stable,\n * and in most cases, this is a problem in your code: In a lot of cases the reason is simply\n * a wrong call to irrklang::IRefCounted::drop(). Be sure you are doing it correctly. (If you are unsure,\n * temporarily remove all calls to irrklang::IRefCounted::drop() and see if this helps.)
    • \n *

\n *
\n *
\n *
\n *\n *\n *\n * \\section concept Starting up the Engine\n *\n * irrKlang is designed so that it is very easy to achieve everything, its interface should\n * be very simple to use. The @ref quickstartexample shows how to play and mp3 file, and there\n * is another example, @ref quickstartexample2, showing some few more details.
\n * To start up the sound engine, you simply need to call createIrrKlangDevice(). To shut it down,\n * call IRefCounted::drop():\n *\n * \\code\n * #include \n *\n * // ...\n *\n * // start up the engine\n * irrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();\n *\t\n * // ...\n * \n * // after finished,\n * // close the engine again, similar as calling 'delete'\n * engine->drop(); \n * \\endcode\n *\n * The createIrrKlangDevice() function also accepts several parameters, so that you can \n * specify which sound driver should be used, if plugins should be used, if irrKlang\n * should run in multithreaded mode, and similar.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section playingSounds Playing Sounds\n *\n * Once you have irrKlang running (like in @ref concept), you can start playing sounds:\n *\n * \\code\n * engine->play2D(\"someSoundFile.wav\"); \n * \\endcode\n *\n * This works with all supported file types. You can replace \"someSoundFile.wav\" with\n * \"someSoundFile.mp3\", or \"someSoundFile.ogg\", for example.
\n * To play a sound looped, set the second parameter to 'true':\n *\n * \\code\n * engine->play2D(\"myMusic.mp3\", true); \n * \\endcode \n *\n * To stop this looping sound again, use engine->\\link irrklang::ISoundEngine::stopAllSounds stopAllSounds()\\endlink to stop all sounds, or\n * irrklang::ISound::stop() if you only want to stop that single sound. @ref changingSounds\n * shows how to get to that ISound interface.\n *
\n *
\n *
\n *
\n *\n *\n * \\section changingSounds Influencing Sounds during Playback\n * To influence parameters of the sound such as pan, volume or playback speed during runtime, \n * to get the play position or stop playback of single playing sounds,\n * you can use the irrklang::ISound interface. \n * irrklang::ISoundEngine::play2D (but also play3D) returns\n * a pointer to this interface when its third ('startPaused') or fourth ('track') parameter\n * was set to true:\n *\n * \\code\n * irrklang::ISound* snd = engine->play2D(\"myMusic.mp3\", true, false, true); \n *\n * // ...\n *\n * if (snd)\n * snd->setVolume(someNewValue);\n * \n * // ...\n * \n * if (snd)\n * {\n * snd->drop(); // don't forget to release the pointer once it is no longer needed by you\n * snd = 0;\n * }\n * \\endcode\n *\n * The irrklang::ISound interface can also be used to test if the sound has been finished, \n * set event receivers, pause and unpause sounds and similar. \n *
\n *
\n *
\n *
\n *\n *\n * \\section soundSources Using Sound Sources\n *\n * To be more flexible playing back sounds, irrKlang uses the concept of sound sources. \n * A sound source can be simply the name of a sound file, such as \"sound.wav\". It is possible\n * to add \"sound.wav\" as sound source to irrKlang, and play it using the sound source pointer:\n *\n * \\code\n * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile(\"shoot.wav\"); \n *\n * engine->play2D(shootSound);\n *\n * // note: you don't need to drop() the shootSound if you don't use it anymore\n * \\endcode\n *\n * The advantage of using irrklang::ISoundSource is that it is possible to set \n * default values for this source, such\n * as volume or distances if it should be used as 3D sound:\n *\n * \\code\n * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile(\"shoot.wav\"); \n *\n * shootSound->setDefaultVolume(0.5f);\n *\n * // shootSound will now be played with half its sound volume by default:\n * engine->play2D(shootSound);\n * \\endcode\n *\n * It is also possible to have multiple settings for the same sound file:\n *\n * \\code\n * irrklang::ISoundSource* shootSound = engine->addSoundSourceFromFile(\"shoot.wav\"); \n * irrklang::ISoundSource* shootSound2 = engine->addSoundSourceAlias(shootSound, \"silentShoot\"); \n *\n * shootSound2->setDefaultVolume(0.1f);\n *\n * // shootSound will now be played with 100% of its sound volume by default,\n * // shootSound2 will now be played 10% of its sound volume by default. It is \n * // also possible to play it using engine->play(\"silentShoot\"), now.\n * \\endcode\n *\n * Using addSoundSourceFromMemory(), it is also possible to play sounds back directly from memory,\n * without files.\n * Of course, it is not necessary to use sound sources. Using irrklang::ISound, it is\n * possible to change the settings of all sounds, too. But using sound sources, it is\n * not necessary to do this every time a sound is played.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section sound3d 3D Sound\n *\n * There is nothing difficult in playing sounds in 3D using irrKlang: Instead of using \n * irrklang::ISoundEngine::play2D(), just use irrklang::ISoundEngine::play3D(), which\n * takes a 3D position as additional parameter:\n *\n * \\code\n * irrklang::vec3df position(23,70,90);\n * engine->play3D(\"yourSound.wav\", position);\n * \\endcode\n *\n * But to make it sound realistic, you need to set a minimal sound\n * distance: If your sound is caused by a bee, it will usually have a smaller\n * sound radius than for example a jet engine. You can set default values using sound sources\n * (see @ref soundSources) or set these values after you have started the sound paused:\n *\n * \\code\n * irrklang::vec3df position(23,70,90);\n *\n * // start the sound paused:\n * irrklang::ISound* snd = engine->play3D(\"yourSound.wav\", position, false, true);\n *\n * if (snd)\n * {\n * snd->setMinDistance(30.0f); // a loud sound\n * snd->setIsPaused(false); // unpause the sound\n * }\n * \\endcode\n * \n * There is also the possibility to change the maxDistance, but it is only necessary to change this\n * in very rare circumstances.\n * If the sound moves, it is also a good idea to update its position from time to time:\n * \n * \\code\n * if (snd)\n * snd->setPosition(newPosition);\n * \\endcode\n *\n * And don't forget to drop() the sound after you don't need it anymore. If you do, it's \n * nothing severe because irrKlang will still clean up the sounds resources after it has\n * finished, but you still would waste some few bytes of memory:\n * \n * \\code\n * if (snd)\n * {\n * snd->drop();\n * snd = 0;\n * }\n * \\endcode\n *\n * To update the position of yourself, the listener of the 3D sounds, use this from\n * time to time:\n *\n * \\code\n * irrklang::vec3df position(0,0,0); // position of the listener\n * irrklang::vec3df lookDirection(10,0,10); // the direction the listener looks into\n * irrklang::vec3df velPerSecond(0,0,0); // only relevant for doppler effects\n * irrklang::vec3df upVector(0,1,0); // where 'up' is in your 3D scene\n *\n * engine->setListenerPosition(position, lookDirection, velPerSecond, upVector);\n * \\endcode\n *\n *
\n *
\n *
\n *
\n *\n *\n * \\section removingSounds Removing Sounds\n *\n * irrKlang manages the memory usage of sounds by itself, so usually, you don't have\n * to care about memory management. But if you know you need to reduce the\n * amount of used memory at a certain point in your program, you can do this:\n *\n * \\code\n * engine->removeAllSoundSources(); \n * \\endcode\n *\n * This will remove all sounds and also cause all sounds to be stopped. To remove single\n * sounds from the engine, use:\n *\n * \\code\n * engine->removeSoundSource(pointerToSomeSoundSource); \n * // or:\n * engine->removeSoundSource(\"nameOfASoundFile.wav\"); \n * \\endcode\n *\n * Note: Only removing buffered sounds will reduce the amount of memory used by irrKlang, streamed\n * sounds don't occupy a lot of memory when they are not played.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section events Using Sound Events\n *\n * In order to wait for a sound to be finished, it is simply possible to \n * poll irrklang::ISound::isFinished(). Another way would be to constantly use \n * irrklang::ISoundEngine::isCurrentlyPlaying to test wether a sound with that name or source\n * is currently playing. But of course, an event based approach is a lot nicer. That's why irrKlang\n * supports sound events.
\n * The key to sound events is the method \n * \\link irrklang::ISound::setSoundStopEventReceiver setSoundStopEventReceiver \\endlink\n * of the irrklang::ISound interface\n * (See @ref changingSounds on how to get the ISound interface):\n *\n * \\code\n * irrklang::ISound* snd = engine->play2D(\"speech.mp3\", false, false, true); \n * if (snd)\n * snd->setSoundStopEventReceiver(yourEventReceiver, 0);\n * \\endcode\n * \n * The optional second parameter of setSoundStopEventReceiver is a user pointer, set it to whatever you like.\n * 'yourEventReceiver' must be an implementation of the irrklang::ISoundStopEventReceiver interface.
\n * A whole implementation could look like this:\n *\n * \\code\n * class MySoundEndReceiver : public irrklang::ISoundStopEventReceiver\n * {\n * public:\n * virtual void OnSoundStopped (irrklang::ISound* sound, irrklang::E_STOP_EVENT_CAUSE reason, void* userData)\n * {\n * // called when the sound has ended playing\n * printf(\"sound has ended\");\n * }\n * }\n *\n * // ...\n *\n * MySoundEndReceiver* myReceiver = new MySoundEndReceiver();\n * irrklang::ISound* snd = engine->play2D(\"speech.mp3\", false, false, true); \n * if (snd)\n * snd->setSoundStopEventReceiver(myReceiver);\n *\n * myReceiver->drop(); // similar to delete\n * \\endcode\n * \n * The irrklang::ISoundStopEventReceiver::OnSoundStopped() method is guaranteed to be called when a sound or sound stream has stopped,\n * either because the sound reached its playback end, its sound source was removed,\n * ISoundEngine::stopAllSounds() has been called or the whole engine was deleted.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section memoryPlayback Memory Playback\n *\n * Using irrKlang, it is easily possible to play sounds directly from memory instead out of \n * files. There is an example project showing this: In the SDK, in /examples/03.MemoryPlayback.\n * But in short, it simply works by adding the memory as sound source (See @ref soundSources for \n * details about sound sources):\n *\n * \\code\n * engine->addSoundSourceFromMemory(pointerToMemory, memorySize, \"nameforthesound.wav\");\n * \n * // play sound now\n * engine->play2D(\"nameforthesound.wav\");\n * \\endcode\n *\n * Or using a sound source pointer:\n *\n * \\code\n * irrklang::ISoundSource* snd = \n * engine->addSoundSourceFromMemory(pointerToMemory, memorySize, \"nameforthesound.wav\");\n * \n * // play sound now\n * engine->play2D(snd);\n * \\endcode\n *\n * Note: It is also possible to overwrite the file access directly, don't use this Memory Playback\n * feature for this. See @ref fileOverriding for details.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section effects Sound Effects\n *\n * irrKlang supports the effects Chorus, Compressor, Distortion, Echo, Flanger\n * Gargle, 3DL2Reverb, ParamEq and WavesReverb, when using the sound driver \n * irrklang::ESOD_DIRECT_SOUND_8, which selected by default when using Windows.
\n *\n * Using the irrklang::ISound interface, you can obtain the irrklang::ISoundEffectControl\n * interface if the sound device supports sound effects and the last parameter ('enableSoundEffects')\n * was set to true when calling play2D():\n *\n * \\code\n * irrklang::ISound* snd = engine->play2D(\"sound.wav\", true, false, true, ESM_AUTO_DETECT, true);\n *\n * if (snd)\n * {\n * irrklang::ISoundEffectControl* fx = snd->getSoundEffectControl();\n * if (fx)\n * {\n * // enable the echo sound effect for this sound\n * fx->enableEchoSoundEffect();\n * }\n * }\n * \n * snd->drop();\n * \\endcode\n *\n * This enabled the echo sound effect for this sound. The method also supports a lot of \n * parameters, and can be called multiple times to change those parameters over time if wished.\n * There are a lot of other sound effects, see irrklang::ISoundEffectControl for details.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section fileOverriding Overriding File Access\n *\n * It is possible to let irrKlang use your own file access functions.\n * This is useful if you want to read sounds from other sources than\n * just files, for example from custom internet streams or \n * an own encrypted archive format. There is an example in the SDK in \n * examples/04.OverrideFileAccess which shows this as well.
\n *\n * The only thing to do for this is to implement your own irrklang::IFileFactory,\n * and set it in irrKlang using irrklang::ISoundEngine::addFileFactory():\n *\n * \\code\n * // a class implementing the IFileFactory interface to override irrklang file access\n * class CMyFileFactory : public irrklang::IFileFactory\n * {\n * public:\n *\n * // Opens a file for read access. Simply return 0 if file not found.\n * virtual irrklang::IFileReader* createFileReader(const ik_c8* filename)\n * {\n * // return your own irrklang::IFileReader implementation here, for example like that:\n * return new CMyReadFile(filename);\n * }\n * };\n * \n * // ...\n *\n * CMyFileFactory* myFactory = new CMyFileFactory();\n * engine->addFileFactory(myFactory);\n * myFactory->drop();\n * \\endcode\n *\n * For a full example implementation, just take a look into the SDK in examples/04.OverrideFileAccess.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section audioDecoders Adding Audio Decoders\n *\n * To add support for new file formats, it is possible to add new audio decoders\n * to irrKlang. \n * The only thing to do for this is to implement your own irrklang::IAudioStreamLoader,\n * and irrklang::IAudioStream, and set it in irrKlang using \n * irrklang::ISoundEngine::registerAudioStreamLoader():\n *\n * \\code\n * class NewAudioStreamLoader : public irrklang::IAudioStreamLoader\n * {\n * // ... returns NewAudioDecoder and the used file name suffices.\n * };\n *\n * class NewAudioDecoder : public irrklang::IAudioStream\n * {\n * public:\n * // ... decodes the new file format\n * };\n *\n * // ...\n *\n * NewAudioDecoder* loader = new NewAudioDecoder();\n * engine->registerAudioStreamLoader(loader);\n * loader->drop();\n * \\endcode\n * \n * There is an example audio decoder and loader with full source in plugins/ikpMP3, which\n * adds MP3 audio decoding capabilities to irrKlang.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section plugins Creating irrKlang Plugins\n *\n * irrKlang plugins are ikp*.dll (Windows), ikp*.so (Unix) or ikp*.dylib (MacOS) \n * files which are loaded by irrKlang at startup when the \n * irrklang::ESEO_LOAD_PLUGINS was set (which is default) or\n * irrklang::ISoundEngine::loadPlugins() was called.
\n *\n * The plugin only needs to contain the following function which will be called by irrKlang:\n *\n * \\code\n * #ifdef WIN32\n * // Windows version\n * __declspec(dllexport) void __stdcall irrKlangPluginInit(ISoundEngine* engine, const char* version)\n * #else\n * // Linux and Mac OS version\n * void irrKlangPluginInit(ISoundEngine* engine, const char* version)\n * #endif\n * {\n * // your implementation here\n * }\n * \\endcode\n *\n * In there, it is for example possible to extend irrKlang with new audio decoders,\n * see @ref audioDecoders for details.
\n * \n * There is an example plugin with full source in plugins/ikpMP3, which\n * adds MP3 audio decoding capabilities to irrKlang.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section staticLib Using irrKlang as static Lib\n *\n * If you don't want to use the irrKlang.DLL file and link irrKlang statically, you can do this\n * by simply linking to the irrKlang.lib in the bin/win32-visualstudio_lib folder. This folder\n * will only available in the pro versions of irrKlang, which you get when purchasing an irrKlang\n * license.\n *\n * To use irrKlang in this way, just define IRRKLANG_STATIC before including irrklang.h, like this:\n *\n * \\code\n * #define IRRKLANG_STATIC\n * #include \n * \\endcode\n *\n * Of course, IRRKLANG_STATIC can also simply be defined in the project/compiler settings instead of\n * in the source file.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section enumeratingDevices Enumerating sound devices\n *\n * irrKlang uses the default sound device when playing sound when started without parameters. But if you want\n * irrKlang to playback sound on one specific sound device, you may want to enumerate the available\n * sound devices on your system and select one of them. Use irrklang::createSoundDeviceList() for this. \n * This example code shows how to print a list of all available sound devices on the current system and lets\n * the user choose one of them: \n *\n * \\code\n * int main(int argc, const char** argv)\n * {\n *\t// enumerate devices\n * \n * \tirrklang::ISoundDeviceList* deviceList = createSoundDeviceList();\n * \n * \t// ask user for a sound device\n * \n * \tprintf(\"Devices available:\\n\\n\");\n * \n * \tfor (int i=0; igetDeviceCount(); ++i)\n * \t\tprintf(\"%d: %s\\n\", i, deviceList->getDeviceDescription(i));\n * \n * \tprintf(\"\\nselect a device using the number (or press any key to use default):\\n\\n\");\n * \tint deviceNumber = getch() - '0';\n * \n * \t// create device with the selected driver\n * \n * \tconst char* deviceID = deviceList->getDeviceID(deviceNumber);\n * \t\t\n * \tISoundEngine* engine = createIrrKlangDevice(irrklang::ESOD_AUTO_DETECT, \n * \t irrklang::ESEO_DEFAULT_OPTIONS,\n * \t deviceID);\n * \n * \tdeviceList->drop(); // delete device list\n *\n * // ... use engine now\n * } \n * \\endcode\n *\n * In this way, it is also possible to play back sound using two devices at the same time: Simply \n * create two irrKlang devices with each a different deviceID.
\n * Note: createSoundDeviceList() takes a driver type parameter (such as irrklang::ESOD_DIRECT_SOUND8), which you\n * have to set to the same value as the first parameter you want to use with createIrrKlangDevice(), if it is \n * other than irrklang::ESOD_AUTO_DETECT.\n *
\n *
\n *
\n *
\n *\n *\n *\n * \\section recordingAudio Recording Audio\n *\n * irrKlang is able to record audio from sound capturing devices such as microphones (currently only \n * supported in windows). Use the irrklang::IAudioRecorder interface to do this. The following example shows how\n * to record some audio and play it back again using the engine: \n *\n * \\code\n * int main(int argc, const char** argv)\n * {\n *\tirrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();\n *\tirrklang::IAudioRecorder* recorder = irrklang::createIrrKlangAudioRecorder(engine);\n *\n *\tif (!engine || !recorder)\n *\t{\n *\t\tprintf(\"Could not create audio engine or audio recorder\\n\");\n *\t\treturn 1;\n *\t}\n *\n *\tprintf(\"\\nPress any key to start recording audio...\\n\");\n *\tgetch();\n *\n *\t// record some audio\n *\n *\trecorder->startRecordingBufferedAudio();\n *\n *\tprintf(\"\\nRECORDING. Press any key to stop...\\n\");\n *\tgetch();\n *\n *\trecorder->stopRecordingAudio();\n *\n *\tprintf(\"\\nRecording done, recorded %dms of audio.\\n\", \n *\t\trecorder->getAudioFormat().FrameCount * 1000 / recorder->getAudioFormat().SampleRate );\n *\tprintf(\"Press any key to play back recorded audio...\\n\");\n *\tgetch();\n *\n *\t// play the recorded audio\n *\trecorder->addSoundSourceFromRecordedAudio(\"myRecordedVoice\");\n *\tengine->play2D(\"myRecordedVoice\", true);\n *\n *\t// wait until user presses a key\n *\tprintf(\"\\nPress any key to quit...\");\n *\tgetch();\n *\n *\trecorder->drop();\n *\tengine->drop(); // delete engine\n *\n *\treturn 0;\n * } \n * \\endcode\n *\n * In order to select a specific audio capturing device for recording, it is necessary to enumerate\n * the available devices. Simply replace the first to lines of code of the example above with code\n * like this to list all devices and select one:\n *\n * \\code\n * // enumerate recording devices and ask user to select one\n * \n * irrklang::ISoundDeviceList* deviceList = irrklang::createAudioRecorderDeviceList();\n *\n * printf(\"Devices available:\\n\\n\");\n *\n * for (int i=0; igetDeviceCount(); ++i)\n * printf(\"%d: %s\\n\", i, deviceList->getDeviceDescription(i));\n *\n * printf(\"\\nselect a device using the number (or press any key to use default):\\n\\n\");\n * int deviceNumber = getch() - '0';\n *\n * // create recording device with the selected driver\n *\n * const char* deviceID = deviceList->getDeviceID(deviceNumber);\n * irrklang::ISoundEngine* engine = irrklang::createIrrKlangDevice();\n * irrklang::IAudioRecorder* recorder = \n * irrklang::createIrrKlangAudioRecorder(engine, irrklang::ESOD_AUTO_DETECT, deviceID);\n *\n * \\endcode\n *\n *
\n *
\n *
\n *
\n *\n *\n * \\section unicode Unicode support\n *\n * irrKlang supports unicode on all operating systems. Internally, it uses UTF8, and all functions accepting strings\n * and file names take UTF8 strings. If you are running irrKlang on Windows, and are using the UNICODE define or using\n * wchar_t* strings directly, you can do this as well. Use the irrKlang provided function makeUTF8fromUTF16string() to \n * convert your wchar_t* string to a char* string.\n *\n * This example shows how:\n *\n * \\code\n * const wchar_t* yourFilename = L\"SomeUnicodeFilename.wav\"; // assuming this is the file name you get from some of your functions\n *\n * const int nBufferSize = 2048; // large enough, but best would be wcslen(yourFilename)*3.\n * char strBuffer[nBufferSize]; \n * irrklang::makeUTF8fromUTF16string(yourFilename, strBuffer, nBufferSize);\n *\n * // now the converted file name is in strBuffer. We can play it for example now:\n * engine->play2D(strBuffer);\n * \\endcode\n *\n * Of course, you can use any other unicode conversion function for this. makeUTF8fromUTF16string() is only provided\n * for convenience.\n *
\n *

Since the top-right vertex of the bottom-right triangle is \nlit and the other 2 vertices of the triangle are not, the bright values interpolates to the other 2 vertices.
