Structs

jpeg_common_struct

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.

jpeg_component_info

jpeg_compress_struct

jpeg_decompress_struct

jpeg_destination_mgr

Error handler object

jpeg_marker_struct

jpeg_memory_mgr

jpeg_progress_mgr

jpeg_source_mgr

jvirt_barray_control

This is an opaque type. Don’t assume size or alignment of this struct.

jvirt_sarray_control

This is an opaque type. Don’t assume size or alignment of this struct.

Enums

JINT_COMPRESS_PROFILE_VALUE

J_BOOLEAN_PARAM

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 opaque jpeg_comp_master and jpeg_decomp_master structs.

Equivalent to C’s void type when used as a pointer.

Constants

The basic DCT block is 8x8 samples

DCTSIZE²

JPEG_LIB_VERSION

lasts until done with image/datastream

JPOOL_PERMANENT

lasts until master record is destroyed

Quantization tables are numbered 0..3
