Please read libjpeg manual for description of functions in this crate.

Structs§
- Routines that are to be used by both halves of the library are declared to receive a pointer to this structure. There are no actual instances of jpeg_common_struct, only of jpeg_compress_struct and jpeg_decompress_struct.
- Error handler object
- This is an opaque type. Don’t assume size or alignment of this struct.
- This is an opaque type. Don’t assume size or alignment of this struct.
Enums§
- These 32-bit GUIDs and the corresponding
jpeg_*_get_*_param()jpeg_*_set_*_param()functions allow for extending the libjpeg API without breaking backward ABI compatibility. The actual parameters are stored in the opaquejpeg_comp_masterandjpeg_decomp_masterstructs.
Constants§
- The basic DCT block is 8x8 samples
- DCTSIZE²
- lasts until done with image/datastream
- lasts until master record is destroyed
- Quantization tables are numbered 0..3
Functions§
- jpeg_new_colormap⚠Deprecated
Type Aliases§

- ptr to some rows (a 2-D sample array)
- a 3-D sample array: top index is color
