Fields

cp_reduce: u32

Set the number of highest resolution levels to be discarded. The image resolution is effectively divided by 2 to the power of the number of discarded levels. The reduce factor is limited by the smallest total number of decomposition levels among tiles. if != 0, then original dimension divided by 2^(reduce); if == 0 or not used, image is decoded to the full resolution

cp_layer: u32

Set the maximum number of quality layers to decode. If there are less quality layers than the specified number, all the quality layers are decoded. if != 0, then only the first “layer” layers are decoded; if == 0 or not used, all the quality layers are decoded

infile: [i8; 4096]

input file name

outfile: [i8; 4096]

decod_format: i32
