Structs

JHUFF_TBL
JQUANT_TBL
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
jpeg_error_mgr	Error handler object
jpeg_marker_struct
jpeg_memory_mgr
jpeg_progress_mgr
jpeg_scan_info
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.
msg_parm_union

Enums

FILE
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.
J_COLOR_SPACE
J_DCT_METHOD
J_DITHER_MODE
J_FLOAT_PARAM
J_INT_PARAM
c_void	Equivalent to C’s void type when used as a pointer.
jpeg_marker

Constants

DCTSIZE	The basic DCT block is 8x8 samples
DCTSIZE2	DCTSIZE²
JPEG_LIB_VERSION
JPOOL_IMAGE	lasts until done with image/datastream
JPOOL_PERMANENT	lasts until master record is destroyed
NUM_QUANT_TBLS	Quantization tables are numbered 0..3
