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. By -// default this is set to (1 << 24), which is 16777216, but that's still -// very big. - -#ifndef STBI_NO_STDIO -#include -#endif // STBI_NO_STDIO - -#define STBI_VERSION 1 - -enum -{ - STBI_default = 0, // only used for desired_channels - - STBI_grey = 1, - STBI_grey_alpha = 2, - STBI_rgb = 3, - STBI_rgb_alpha = 4 -};
