Decompression parameters

Fields

cp_reduce: OPJ_UINT32

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: OPJ_UINT32

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: [c_char; 4096]

input file name

outfile: [c_char; 4096]

output file name

decod_format: c_int

input file format 0: J2K, 1: JP2, 2: JPT

cod_format: c_int

output file format 0: PGX, 1: PxM, 2: BMP

DA_x0: OPJ_UINT32

Decoding area left boundary

DA_x1: OPJ_UINT32

Decoding area right boundary

DA_y0: OPJ_UINT32

Decoding area up boundary

DA_y1: OPJ_UINT32

Decoding area bottom boundary

m_verbose: OPJ_BOOL

Verbose mode

tile_index: OPJ_UINT32

tile number of the decoded tile

nb_tile_to_decode: OPJ_UINT32

Nb of tile to decode

jpwl_correct: OPJ_BOOL

activates the JPWL correction capabilities

jpwl_exp_comps: c_int

expected number of components

jpwl_max_tiles: c_int

maximum number of tiles

flags: c_uint
