The pixel data consists of *y scanlines of *x pixels, +// with each pixel consisting of N interleaved 8-bit components; the first +// pixel pointed to is top-left-most in the image. There is no padding between +// image scanlines or between pixels, regardless of format. The number of +// components N is 'desired_channels' if desired_channels is non-zero, or +// *channels_in_file otherwise. If desired_channels is non-zero, +// *channels_in_file has the number of components that _would_ have been +// output otherwise. E.g. if you set desired_channels to 4, you will always +// get RGBA output, but you can check *channels_in_file to see if it's trivially +// opaque because e.g. there were only 3 channels in the source image. +// +// An output image with N components has the following components interleaved +// in this order in each pixel: +// +// N=#comp components +// 1 grey +// 2 grey, alpha +// 3 red, green, blue +// 4 red, green, blue, alpha +// +// If image loading fails for any reason, the return value will be NULL, +// and *x, *y, *channels_in_file will be unchanged. The function +// stbi_failure_reason() can be queried for an extremely brief, end-user +// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS +// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly +// more user-friendly ones. +// +// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. +// +// To query the width, height and component count of an image without having to +// decode the full file, you can use the stbi_info family of functions: +// +// int x,y,n,ok; +// ok = stbi_info(filename, &x, &y, &n); +// // returns ok=1 and sets x, y, n if image is a supported format, +// // 0 otherwise. +// +// Note that stb_image pervasively uses ints in its public API for sizes, +// including sizes of memory buffers. This is now part of the API and thus +// hard to change without causing breakage. As a result, the various image +// loaders all have certain limits on image size; these differ somewhat +// by format but generally boil down to either just under 2GB or just under +// 1GB. When the decoded image would be larger than this, stb_image decoding +// will fail. +// +// Additionally, stb_image will reject image files that have any of their +// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, +// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, +// the only way to have an image with such dimensions load correctly +// is for it to have a rather extreme aspect ratio. Either way, the +// assumption here is that such larger images are likely to be malformed +// or malicious. If you do need to load an image with individual dimensions +// larger than that, and it still fits in the overall size limit, you can +// #define STBI_MAX_DIMENSIONS on your own to be something larger. +// +// =========================================================================== +// +// UNICODE: +// +// If compiling for Windows and you wish to use Unicode filenames, compile +// with +// #define STBI_WINDOWS_UTF8 +// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert +// Windows wchar_t filenames to utf8. +// +// =========================================================================== +// +// Philosophy +// +// stb libraries are designed with the following priorities: +// +// 1. easy to use +// 2. easy to maintain +// 3. good performance +// +// Sometimes I let "good performance" creep up in priority over "easy to maintain", +// and for best performance I may provide less-easy-to-use APIs that give higher +// performance, in addition to the easy-to-use ones. Nevertheless, it's important +// to keep in mind that from the standpoint of you, a client of this library, +// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. +// +// Some secondary priorities arise directly from the first two, some of which +// provide more explicit reasons why performance can't be emphasized. +// +// - Portable ("ease of use") +// - Small source code footprint ("easy to maintain") +// - No dependencies ("ease of use") +// +// =========================================================================== +// +// I/O callbacks +// +// I/O callbacks allow you to read from arbitrary sources, like packaged +// files or some other source. Data read from callbacks are processed +// through a small internal buffer (currently 128 bytes) to try to reduce +// overhead. +// +// The three functions you must define are "read" (reads some bytes of data), +// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). +// +// =========================================================================== +// +// SIMD support +// +// The JPEG decoder will try to automatically use SIMD kernels on x86 when +// supported by the compiler. For ARM Neon support, you must explicitly +// request it. +// +// (The old do-it-yourself SIMD API is no longer supported in the current +// code.) +// +// On x86, SSE2 will automatically be used when available based on a run-time +// test; if not, the generic C versions are used as a fall-back. On ARM targets, +// the typical path is to have separate builds for NEON and non-NEON devices +// (at least this is true for iOS and Android). Therefore, the NEON support is +// toggled by a build flag: define STBI_NEON to get NEON loops. +// +// If for some reason you do not want to use any of SIMD code, or if +// you have issues compiling it, you can disable it entirely by +// defining STBI_NO_SIMD. +// +// =========================================================================== +// +// HDR image support (disable by defining STBI_NO_HDR) +// +// stb_image supports loading HDR images in general, and currently the Radiance +// .HDR file format specifically. You can still load any file through the existing +// interface; if you attempt to load an HDR file, it will be automatically remapped +// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; +// both of these constants can be reconfigured through this interface: +// +// stbi_hdr_to_ldr_gamma(2.2f); +// stbi_hdr_to_ldr_scale(1.0f); +// +// (note, do not use _inverse_ constants; stbi_image will invert them +// appropriately). +// +// Additionally, there is a new, parallel interface for loading files as +// (linear) floats to preserve the full dynamic range: +// +// float *data = stbi_loadf(filename, &x, &y, &n, 0); +// +// If you load LDR images through this interface, those images will +// be promoted to floating point values, run through the inverse of +// constants corresponding to the above: +// +// stbi_ldr_to_hdr_scale(1.0f); +// stbi_ldr_to_hdr_gamma(2.2f); +// +// Finally, given a filename (or an open file or memory block--see header +// file for details) containing image data, you can query for the "most +// appropriate" interface to use (that is, whether the image is HDR or +// not), using: +// +// stbi_is_hdr(char *filename); +// +// =========================================================================== +// +// iPhone PNG support: +// +// We optionally support converting iPhone-formatted PNGs (which store +// premultiplied BGRA) back to RGB, even though they're internally encoded +// differently. To enable this conversion, call +// stbi_convert_iphone_png_to_rgb(1). +// +// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per +// pixel to remove any premultiplied alpha *only* if the image file explicitly +// says there's premultiplied data (currently only happens in iPhone images, +// and only if iPhone convert-to-rgb processing is on). +// +// =========================================================================== +// +// ADDITIONAL CONFIGURATION +// +// - You can suppress implementation of any of the decoders to reduce +// your code footprint by #defining one or more of the following +// symbols before creating the implementation. +// +// STBI_NO_JPEG +// STBI_NO_PNG +// STBI_NO_BMP +// STBI_NO_PSD +// STBI_NO_TGA +// STBI_NO_GIF +// STBI_NO_HDR +// STBI_NO_PIC +// STBI_NO_PNM (.ppm and .pgm) +// +// - You can request *only* certain decoders and suppress all other ones +// (this will be more forward-compatible, as addition of new decoders +// doesn't require you to disable them explicitly): +// +// STBI_ONLY_JPEG +// STBI_ONLY_PNG +// STBI_ONLY_BMP +// STBI_ONLY_PSD +// STBI_ONLY_TGA +// STBI_ONLY_GIF +// STBI_ONLY_HDR +// STBI_ONLY_PIC +// STBI_ONLY_PNM (.ppm and .pgm) +// +// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still +// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB +// +// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater +// than that size (in either width or height) without further processing. +// This is to let programs in the wild set an upper bound to prevent +// denial-of-service attacks on untrusted data, as one could generate a +// valid image of gigantic dimensions and force stb_image to allocate a +// huge block of memory and spend disproportionate time decoding it.

To override the + memory allocation, before the implementation #include, add a: + + #define STBIR_MALLOC(size,user_data) ... + #define STBIR_FREE(ptr,user_data) ... + + Each resize makes exactly one call to malloc/free (unless you use the + extended API where you can do one allocation for many resizes). Under + address sanitizer, we do separate allocations to find overread/writes. + + PERFORMANCE + This library was written with an emphasis on performance. When testing + stb_image_resize with RGBA, the fastest mode is STBIR_4CHANNEL with + STBIR_TYPE_UINT8 pixels and CLAMPed edges (which is what many other resize + libs do by default). Also, make sure SIMD is turned on of course (default + for 64-bit targets). Avoid WRAP edge mode if you want the fastest speed. + + This library also comes with profiling built-in. If you define STBIR_PROFILE, + you can use the advanced API and get low-level profiling information by + calling stbir_resize_extended_profile_info() or stbir_resize_split_profile_info() + after a resize. + + SIMD + Most of the routines have optimized SSE2, AVX, NEON and WASM versions. + + On Microsoft compilers, we automatically turn on SIMD for 64-bit x64 and + ARM; for 32-bit x86 and ARM, you select SIMD mode by defining STBIR_SSE2 or + STBIR_NEON. For AVX and AVX2, we auto-select it by detecting the /arch:AVX + or /arch:AVX2 switches. You can also always manually turn SSE2, AVX or AVX2 + support on by defining STBIR_SSE2, STBIR_AVX or STBIR_AVX2. + + On Linux, SSE2 and Neon is on by default for 64-bit x64 or ARM64. For 32-bit, + we select x86 SIMD mode by whether you have -msse2, -mavx or -mavx2 enabled + on the command line. For 32-bit ARM, you must pass -mfpu=neon-vfpv4 for both + clang and GCC, but GCC also requires an additional -mfp16-format=ieee to + automatically enable NEON. + + On x86 platforms, you can also define STBIR_FP16C to turn on FP16C instructions + for converting back and forth to half-floats. This is autoselected when we + are using AVX2. Clang and GCC also require the -mf16c switch. ARM always uses + the built-in half float hardware NEON instructions. + + You can also tell us to use multiply-add instructions with STBIR_USE_FMA. + Because x86 doesn't always have fma, we turn it off by default to maintain + determinism across all platforms. If you don't care about non-FMA determinism + and are willing to restrict yourself to more recent x86 CPUs (around the AVX + timeframe), then fma will give you around a 15% speedup. + + You can force off SIMD in all cases by defining STBIR_NO_SIMD. You can turn + off AVX or AVX2 specifically with STBIR_NO_AVX or STBIR_NO_AVX2. AVX is 10% + to 40% faster, and AVX2 is generally another 12%. + + ALPHA CHANNEL + Most of the resizing functions provide the ability to control how the alpha + channel of an image is processed. + + When alpha represents transparency, it is important that when combining + colors with filtering, the pixels should not be treated equally; they + should use a weighted average based on their alpha values. For example, + if a pixel is 1% opaque bright green and another pixel is 99% opaque + black and you average them, the average will be 50% opaque, but the + unweighted average and will be a middling green color, while the weighted + average will be nearly black. This means the unweighted version introduced + green energy that didn't exist in the source image. + + (If you want to know why this makes sense, you can work out the math for + the following: consider what happens if you alpha composite a source image + over a fixed color and then average the output, vs. if you average the + source image pixels and then composite that over the same fixed color. + Only the weighted average produces the same result as the ground truth + composite-then-average result.) + + Therefore, it is in general best to "alpha weight" the pixels when applying + filters to them. This essentially means multiplying the colors by the alpha + values before combining them, and then dividing by the alpha value at the + end. + + The computer graphics industry introduced a technique called "premultiplied + alpha" or "associated alpha" in which image colors are stored in image files + already multiplied by their alpha. This saves some math when compositing, + and also avoids the need to divide by the alpha at the end (which is quite + inefficient). However, while premultiplied alpha is common in the movie CGI + industry, it is not commonplace in other industries like videogames, and most + consumer file formats are generally expected to contain not-premultiplied + colors. For example, Photoshop saves PNG files "unpremultiplied", and web + browsers like Chrome and Firefox expect PNG images to be unpremultiplied. + + Note that there are three possibilities that might describe your image + and resize expectation: + + 1. images are not premultiplied, alpha weighting is desired + 2. images are not premultiplied, alpha weighting is not desired + 3. images are premultiplied + + Both case #2 and case #3 require the exact same math: no alpha weighting + should be applied or removed. Only case 1 requires extra math operations; + the other two cases can be handled identically. + + stb_image_resize expects case #1 by default, applying alpha weighting to + images, expecting the input images to be unpremultiplied. This is what the + COLOR+ALPHA buffer types tell the resizer to do. + + When you use the pixel layouts STBIR_RGBA, STBIR_BGRA, STBIR_ARGB, + STBIR_ABGR, STBIR_RX, or STBIR_XR you are telling us that the pixels are + non-premultiplied. In these cases, the resizer will alpha weight the colors + (effectively creating the premultiplied image), do the filtering, and then + convert back to non-premult on exit. + + When you use the pixel layouts STBIR_RGBA_PM, STBIR_RGBA_PM, STBIR_RGBA_PM, + STBIR_RGBA_PM, STBIR_RX_PM or STBIR_XR_PM, you are telling that the pixels + ARE premultiplied. In this case, the resizer doesn't have to do the + premultipling - it can filter directly on the input. This about twice as + fast as the non-premultiplied case, so it's the right option if your data is + already setup correctly. + + When you use the pixel layout STBIR_4CHANNEL or STBIR_2CHANNEL, you are + telling us that there is no channel that represents transparency; it may be + RGB and some unrelated fourth channel that has been stored in the alpha + channel, but it is actually not alpha. No special processing will be + performed. + + The difference between the generic 4 or 2 channel layouts, and the + specialized _PM versions is with the _PM versions you are telling us that + the data *is* alpha, just don't premultiply it. That's important when + using SRGB pixel formats, we need to know where the alpha is, because + it is converted linearly (rather than with the SRGB converters). + + Because alpha weighting produces the same effect as premultiplying, you + even have the option with non-premultiplied inputs to let the resizer + produce a premultiplied output. Because the intially computed alpha-weighted + output image is effectively premultiplied, this is actually more performant + than the normal path which un-premultiplies the output image as a final step. + + Finally, when converting both in and out of non-premulitplied space (for + example, when using STBIR_RGBA), we go to somewhat heroic measures to + ensure that areas with zero alpha value pixels get something reasonable + in the RGB values. If you don't care about the RGB values of zero alpha + pixels, you can call the stbir_set_non_pm_alpha_speed_over_quality() + function - this runs a premultiplied resize about 25% faster. That said, + when you really care about speed, using premultiplied pixels for both in + and out (STBIR_RGBA_PM, etc) much faster than both of these premultiplied + options. + + PIXEL LAYOUT CONVERSION + The resizer can convert from some pixel layouts to others. When using the + stbir_set_pixel_layouts(), you can, for example, specify STBIR_RGBA + on input, and STBIR_ARGB on output, and it will re-organize the channels + during the resize. Currently, you can only convert between two pixel + layouts with the same number of channels. + + DETERMINISM + We commit to being deterministic (from x64 to ARM to scalar to SIMD, etc). + This requires compiling with fast-math off (using at least /fp:precise). + Also, you must turn off fp-contracting (which turns mult+adds into fmas)! + We attempt to do this with pragmas, but with Clang, you usually want to add + -ffp-contract=off to the command line as well. + + For 32-bit x86, you must use SSE and SSE2 codegen for determinism. That is, + if the scalar x87 unit gets used at all, we immediately lose determinism. + On Microsoft Visual Studio 2008 and earlier, from what we can tell there is + no way to be deterministic in 32-bit x86 (some x87 always leaks in, even + with fp:strict). On 32-bit x86 GCC, determinism requires both -msse2 and + -fpmath=sse. + + Note that we will not be deterministic with float data containing NaNs - + the NaNs will propagate differently on different SIMD and platforms. + + If you turn on STBIR_USE_FMA, then we will be deterministic with other + fma targets, but we will differ from non-fma targets (this is unavoidable, + because a fma isn't simply an add with a mult - it also introduces a + rounding difference compared to non-fma instruction sequences. + + FLOAT PIXEL FORMAT RANGE + Any range of values can be used for the non-alpha float data that you pass + in (0 to 1, -1 to 1, whatever). However, if you are inputting float values + but *outputting* bytes or shorts, you must use a range of 0 to 1 so that we + scale back properly. The alpha channel must also be 0 to 1 for any format + that does premultiplication prior to resizing. + + Note also that with float output, using filters with negative lobes, the + output filtered values might go slightly out of range. You can define + STBIR_FLOAT_LOW_CLAMP and/or STBIR_FLOAT_HIGH_CLAMP to specify the range + to clamp to on output, if that's important. + + MAX/MIN SCALE FACTORS + The input pixel resolutions are in integers, and we do the internal pointer + resolution in size_t sized integers. However, the scale ratio from input + resolution to output resolution is calculated in float form. This means + the effective possible scale ratio is limited to 24 bits (or 16 million + to 1). As you get close to the size of the float resolution (again, 16 + million pixels wide or high), you might start seeing float inaccuracy + issues in general in the pipeline. If you have to do extreme resizes, + you can usually do this is multiple stages (using float intermediate + buffers). + + FLIPPED IMAGES + Stride is just the delta from one scanline to the next. This means you can + use a negative stride to handle inverted images (point to the final + scanline and use a negative stride). You can invert the input or output, + using negative strides. + + DEFAULT FILTERS + For functions which don't provide explicit control over what filters to + use, you can change the compile-time defaults with: + + #define STBIR_DEFAULT_FILTER_UPSAMPLE STBIR_FILTER_something + #define STBIR_DEFAULT_FILTER_DOWNSAMPLE STBIR_FILTER_something + + See stbir_filter in the header-file section for the list of filters. + + NEW FILTERS + A number of 1D filter kernels are supplied. For a list of supported + filters, see the stbir_filter enum. You can install your own filters by + using the stbir_set_filter_callbacks function. + + PROGRESS + For interactive use with slow resize operations, you can use the the + scanline callbacks in the extended API.

Call stbiw_convert_wchar_to_utf8 to convert + Windows wchar_t filenames to utf8. + +USAGE: + + There are five functions, one for each image file format: + + int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality); + int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); + + void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically + + There are also five equivalent functions that use an arbitrary write function. You are + expected to open/close your file-equivalent before and after calling these: + + int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality); + + where the callback is: + void stbi_write_func(void *context, void *data, int size); + + You can configure it with these global variables: + int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE + int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression + int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode + + + You can define STBI_WRITE_NO_STDIO to disable the file variant of these + functions, so the library will not use stdio.h at all. However, this will + also disable HDR writing, because it requires stdio for formatted output. + + Each function returns 0 on failure and non-0 on success. + + The functions create an image file defined by the parameters. The image + is a rectangle of pixels stored from left-to-right, top-to-bottom. + Each pixel contains 'comp' channels of data stored interleaved with 8-bits + per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is + monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. + The *data pointer points to the first byte of the top-left-most pixel. + For PNG, "stride_in_bytes" is the distance in bytes from the first byte of + a row of pixels to the first byte of the next row of pixels. + + PNG creates output files with the same number of components as the input. + The BMP format expands Y to RGB in the file format and does not + output alpha. + + PNG supports writing rectangles of data even when the bytes storing rows of + data are not consecutive in memory (e.g. sub-rectangles of a larger image), + by supplying the stride between the beginning of adjacent rows. The other + formats do not. (Thus you cannot write a native-format BMP through the BMP + writer, both because it is in BGR order and because it may have padding + at the end of the line.) + + PNG allows you to set the deflate compression level by setting the global + variable 'stbi_write_png_compression_level' (it defaults to 8). + + HDR expects linear float data. Since the format is always 32-bit rgb(e) + data, alpha (if provided) is discarded, and for monochrome data it is + replicated across all three channels. + + TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed + data, set the global variable 'stbi_write_tga_with_rle' to 0. + + JPEG does ignore alpha channels in input data; quality is between 1 and 100. + Higher quality looks better but results in a bigger image. + JPEG baseline (no JPEG progressive). + +CREDITS: + + + Sean Barrett - PNG/BMP/TGA + Baldur Karlsson - HDR + Jean-Sebastien Guay - TGA monochrome + Tim Kelsey - misc enhancements + Alan Hickman - TGA RLE + Emmanuel Julien - initial file IO callback implementation + Jon Olick - original jo_jpeg.cpp code + Daniel Gibson - integrate JPEG, allow external zlib + Aarni Koskela - allow choosing PNG filter + + bugfixes: + github:Chribba + Guillaume Chereau + github:jry2 + github:romigrou + Sergio Gonzalez + Jonas Karlsson + Filip Wasil + Thatcher Ulrich + github:poppolopoppo + Patrick Boettcher + github:xeekworx + Cap Petschulat + Simon Rodriguez + Ivan Tikhonov + github:ignotion + Adam Schackart + Andrew Kensler + +LICENSE + + See end of file for license information. + +*/ + +#ifndef INCLUDE_STB_IMAGE_WRITE_H +#define INCLUDE_STB_IMAGE_WRITE_H + +#include + +// if STB_IMAGE_WRITE_STATIC causes problems, try defining STBIWDEF to 'inline' or 'static inline' +#ifndef STBIWDEF +#ifdef STB_IMAGE_WRITE_STATIC +#define STBIWDEF static +#else +#ifdef __cplusplus +#define STBIWDEF extern "C" +#else +#define STBIWDEF extern +#endif +#endif +#endif + +#ifndef STB_IMAGE_WRITE_STATIC // C++ forbids static forward declarations +STBIWDEF int stbi_write_tga_with_rle;

Thus, anti-aliasing of intersecting shapes may look wrong.

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to .
