Struct mozjpeg_sys::jpeg_component_info [−][src]
Fields
component_id: c_int
identifier for this component (0..255)
component_index: c_int
its index in SOF or cinfo->comp_info[]
h_samp_factor: c_int
horizontal sampling factor (1..4)
v_samp_factor: c_int
vertical sampling factor (1..4)
quant_tbl_no: c_int
quantization table selector (0..3)
dc_tbl_no: c_int
DC entropy table selector (0..3)
These values may vary between scans. For compression, they must be supplied by parameter setup; for decompression, they are read from the SOS marker. The decompressor output side may not use these variables.
ac_tbl_no: c_int
AC entropy table selector (0..3)
width_in_blocks: JDIMENSION
height_in_blocks: JDIMENSION
quant_table: *mut JQUANT_TBL
