- when you control the images you're loading
-
- QUICK NOTES:
- Primarily of interest to game developers and other people who can
- avoid problematic images and only need the trivial interface
-
- JPEG baseline (no JPEG progressive, no oddball channel decimations)
- PNG non-interlaced
- BMP non-1bpp, non-RLE
- TGA (not sure what subset, if a subset)
- PSD (composite view only, no extra channels)
- HDR (radiance rgbE format)
- writes BMP,TGA (define STBI_NO_WRITE to remove code)
- decoded from memory or through stdio FILE (define STBI_NO_STDIO to remove code)

- TODO:
- stbi_info_*
-
- history:
- 1.08 Thatcher Ulrich's PSD code integrated by Nicolas Schulz
- 1.07 attempt to fix C++ warning/errors again
- 1.06 attempt to fix C++ warning/errors again
- 1.05 fix TGA loading to return correct *comp and use good luminance calc
- 1.04 default float alpha is 1, not 255; use 'void *' for stbi_image_free
- 1.03 bugfixes to STBI_NO_STDIO, STBI_NO_HDR
- 1.02 support for (subset of) HDR files, float interface for preferred access to them
- 1.01 fix bug: possible bug in handling right-side up bmps... not sure
- fix bug: the stbi_bmp_load() and stbi_tga_load() functions didn't work at all
- 1.00 interface to zlib that skips zlib header
- 0.99 correct handling of alpha in palette
- 0.98 TGA loader by lonesock; dynamically add loaders (untested)
- 0.97 jpeg errors on too large a file; also catch another malloc failure
- 0.96 fix detection of invalid v value - particleman@mollyrocket forum
- 0.95 during header scan, seek to markers in case of padding
- 0.94 STBI_NO_STDIO to disable stdio usage; rename all #defines the same
- 0.93 handle jpegtran output; verbose errors
- 0.92 read 4,8,16,24,32-bit BMP files of several formats
- 0.91 output 24-bit Windows 3.0 BMP files
- 0.90 fix a few more warnings; bump version number to approach 1.0
- 0.61 bugfixes due to Marc LeBlanc, Christopher Lloyd
- 0.60 fix compiling as c++
- 0.59 fix warnings: merge Dave Moore's -Wall fixes
- 0.58 fix bug: zlib uncompressed mode len/nlen was wrong endian
- 0.57 fix bug: jpg last huffman symbol before marker was >9 bits but less
- than 16 available
- 0.56 fix bug: zlib uncompressed mode len vs. nlen
- 0.55 fix bug: restart_interval not initialized to 0
- 0.54 allow NULL for 'int *comp'
- 0.53 fix bug in png 3->4; speedup png decoding
- 0.52 png handles req_comp=3,4 directly; minor cleanup; jpeg comments
- 0.51 obey req_comp requests, 1-component jpegs return as 1-component,
- on 'test' only check type, not whether we support this variant

-//// begin header file ////////////////////////////////////////////////////
-//
-// Limitations:
-// - no progressive/interlaced support (jpeg, png)
-// - 8-bit samples only (jpeg, png)
-// - not threadsafe
-// - channel subsampling of at most 2 in each dimension (jpeg)
-// - no delayed line count (jpeg) -- IJG doesn't support either
-//
-// Basic usage (see HDR discussion below):
-// 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
-// stbi_image_free(data)
-//
-// Standard parameters:
-// int *x -- outputs image width in pixels
-// int *y -- outputs image height in pixels
-// int *comp -- outputs # of image components in image file
-// int req_comp -- 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. 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 'req_comp' if req_comp is non-zero, or *comp otherwise.
-// If req_comp is non-zero, *comp has the number of components that _would_
-// have been output otherwise. E.g. if you set req_comp to 4, you will always
-// get RGBA output, but you can check *comp to easily see if it's opaque.
-//
-// 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, *comp 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 and BMP images are automatically depalettized.
-//
-//
-// ===========================================================================
-//
-// HDR image support (disable by defining STBI_NO_HDR)
-//
-// stb_image now supports loading HDR images in general, and currently
-// the Radiance .HDR file format, although the support is provided
-// generically. 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);
