Detailed Description

Core decompress parameters.

Field Documentation

◆ cod_format

GRK_SUPPORTED_FILE_FMT _grk_dparameters::cod_format

output file format

◆ cp_layer

uint32_t _grk_dparameters::cp_layer

Set the maximum number of quality layers to decompress.

If there are fewer quality layers than the specified number, all quality layers will be decoded. if != 0, then only the first "layer" layers are decoded; if == 0 or not used, all the quality layers are decoded

◆ cp_reduce

uint32_t _grk_dparameters::cp_reduce

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 greater than zero, then image is deocded to original dimension divided by 2^(cp_reduce); if equal to zero or not used, image is decoded to full resolution

◆ DA_x0

uint32_t _grk_dparameters::DA_x0

Decoding area left boundary.

◆ DA_x1

uint32_t _grk_dparameters::DA_x1

Decoding area right boundary.

◆ DA_y0

uint32_t _grk_dparameters::DA_y0

Decoding area up boundary.

◆ DA_y1

uint32_t _grk_dparameters::DA_y1

Decoding area bottom boundary.

◆ decod_format

GRK_SUPPORTED_FILE_FMT _grk_dparameters::decod_format

input file format

◆ flags

uint32_t _grk_dparameters::flags

◆ infile

char _grk_dparameters::infile[GRK_PATH_LEN]

input file name

◆ m_verbose

bool _grk_dparameters::m_verbose

Verbose mode.

◆ nb_tile_to_decode

uint32_t _grk_dparameters::nb_tile_to_decode

Number of tiles to decompress.

◆ outfile

char _grk_dparameters::outfile[GRK_PATH_LEN]

output file name

◆ tile_index

uint16_t _grk_dparameters::tile_index

tile number of the decompressed tile
