| OPJ_UINT32 opj_dparameters::cp_layer | 
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
Referenced by opj_j2k_setup_decoder(), and opj_set_default_decoder_parameters().
| OPJ_UINT32 opj_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 != 0, then original dimension divided by 2^(reduce); if == 0 or not used, image is decoded to the full resolution
