output file format
uint16_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 decompressed. if != 0, then only the first "layer" layers are decompressed; if == 0 or not used, all the quality layers are decompressed

uint8_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 decompressed to full resolution
