$ opj_decompress -h

Decoding area

- Changed state: Fixed
- Added labels: Milestone-Release2.1
from openjpeg.
The decode area didn't take into account the case where the file is not tiled.
In this case all the image is decoded and only the decoded area is written in
the output file.

Reformulating OP request. OpenJPEG should provide a low level functionality to
decode only portion of the image based on precinct (case image is single tiled
for example). Until issue 94 is solved, this cannot be fixed.
