Encoding failure for 1-bit images with opj_compress

Expected behavior and actual behavior.
1-bit images should encode correctly, however instead I'm getting the following, with variations on the remaining/needed:
[INFO] tile number 1 / 1
[ERROR] opj_t2_encode_packet(): only 203 bytes remaining in output buffer. 755 needed.
[ERROR] Cannot encode tile
failed to encode image: opj_encode
failed to encode image: opj_end_compress
failed to encode image
Steps to reproduce the problem.
Run opj_compress -i 1bit_failure.raw -o 1bit.j2k -F 123,234,1,1,u
Other things I've noticed:
- A smaller image works OK with
opj_compress -i 1bit_success.raw -o 1bit.j2k -F 70,100,1,1,u
opj_compress -i 1bit_failure.raw -o 1bit.j2k -F 123,234,1,2,u
(i.e. 2-bit precision) also works OK
Test files (rename extensions to raw
) - these are just purely random 1-bit images:
Operating system
Ubuntu 22.04
openjpeg version
Current master
