OPJ_LIMIT_DECODING | cp_limit_decoding |
Specify whether the decoding should be done on the entire codestream, or be limited to the main header Limiting the decoding to the main header makes it possible to extract the characteristics of the codestream if == NO_LIMITATION, the entire codestream is decoded; if == LIMIT_TO_MAIN_HEADER, only the main header is decoded;.

int 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

int 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
