BMP File Reader/Writer Implementation
Anton Gerdelan
Version: 3.1 18 March 2020.
Licence: see bottom of file.
C89 ( Implementation is C99 )
Contributors:
- Anton Gerdelan - Initial code.
- Saija Sorsa - Fuzz testing.
Instructions:
- Just drop this header, and the matching .c file into your project.
- To get debug printouts during parsing define APG_BMP_DEBUG_OUTPUT.
Advantages:
- The implementation is fast, simple, and supports more formats than most BMP reader libraries.
- The reader function is fuzzed with AFL https://lcamtuf.coredump.cx/afl/.
- The reader is robust to large files and malformed files, and will return any valid partial data in an image.
- Reader supports 32bpp (with alpha channel), 24bpp, 8bpp, 4bpp, and 1bpp monochrome BMP images.
- Reader handles indexed BMP images using a colour palette.
- Writer supports 32bpp RGBA and 24bpp uncompressed RGB images.
Current Limitations:
- 16-bit images not supported (don't have any samples to test on).
- No support for interleaved channel bit layouts eg RGB101010 RGB555 RGB565.
- No support for compressed BMP images, although in practice these are not used.
- Output images with alpha channel are written in BITMAPINFOHEADER format.
For better alpha support in other apps the 124-bit v5 header could be used instead,
at the cost of some backward compatibility and bloat.
To Do:
- FUZZING
- create a unique fuzz test set for (8,4,1 BPP).
- (maybe) FEATURE Flipping the image based on negative width and height in header, and/or function arguments.
- (maybe) PERF ifdef intrinsics/asm for bitscan. Platform-specific code so won't include unless necessary.
- (maybe) FEATURE Add parameter for padding output memory to eg 4-byte alignment or n channels.
- (maybe) FEATURE Improved apps support in alpha channel writing (using v5 header).
