-/* stb_image - v2.30 - public domain image loader - http://nothings.org/stb
- no warranty implied; use at your own risk
-
- Do this:
- #define STB_IMAGE_IMPLEMENTATION
- before you include this file in *one* C or C++ file to create the implementation.
-
- // i.e. it should look like this:
- #include ...
- #include ...
- #include ...
- #define STB_IMAGE_IMPLEMENTATION
- #include "stb_image.h"
-
- You can #define STBI_ASSERT(x) before the #include to avoid using assert.h.
- And #define STBI_MALLOC, STBI_REALLOC, and STBI_FREE to avoid using malloc,realloc,free
-
-
- QUICK NOTES:
- Primarily of interest to game developers and other people who can
- avoid problematic images and only need the trivial interface
-
- JPEG baseline & progressive (12 bpc/arithmetic not supported, same as stock IJG lib)
- PNG 1/2/4/8/16-bit-per-channel
-
- TGA (not sure what subset, if a subset)
- BMP non-1bpp, non-RLE
- PSD (composited view only, no extra channels, 8/16 bit-per-channel)
-
- GIF (*comp always reports as 4-channel)
- HDR (radiance rgbE format)
- PIC (Softimage PIC)
- PNM (PPM and PGM binary only)
-
- Animated GIF still needs a proper API, but here's one way to do it:
- http://gist.github.com/urraka/685d9a6340b26b830d49
-
- - decode from memory or through FILE (define STBI_NO_STDIO to remove code)
- - decode from arbitrary I/O callbacks
- - SIMD acceleration on x86/x64 (SSE2) and ARM (NEON)

-
-// DOCUMENTATION
-//
-// Limitations:
-// - no 12-bit-per-channel JPEG
-// - no JPEGs with arithmetic coding
-// - GIF always returns *comp=4
-//
-// Basic usage (see HDR discussion below for HDR usage):
-// int x,y,n;
-// unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
-// // ... process data if not NULL ...
-// // ... x = width, y = height, n = # 8-bit components per pixel ...
-// // ... replace '0' with '1'..'4' to force that many components per pixel
-// // ... but 'n' will always be the number that it would have been if you said 0
-// stbi_image_free(data);
-//
-// Standard parameters:
-// int *x -- outputs image width in pixels
-// int *y -- outputs image height in pixels
-// int *channels_in_file -- outputs # of image components in image file
-// int desired_channels -- if non-zero, # of image components requested in result
-//
-// The return value from an image loader is an 'unsigned char *' which points
-// to the pixel data, or NULL on an allocation failure or if the image is
-// corrupt or invalid. 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.
