Subject RE: How can I write JPEG2000 encoded images in PDF?

for PDFBox. Couple that with the difficulty of encoding the format means there's a non-zero

This is true. I have to add that the jai encoder (jj2000) is also broken in encoding RGB images
(need to be converted to BGR images), an easy task yet a broken implementation it is.
