Decoding and conversion of JPEG 2000 images now work correctly
Previously, decoding and conversion of JPEG 2000 images did not work correctly due to a bug in the `openjpeg` library. With this update, the underlying source code has been fixed, and decoding and conversion of JPEG 2000 images now works as expected.

This is an issue in openjpeg package. I'm able to reproduce the same errors when running "j2k_to_image" on the extracted image. Steps: 1) pdfimages -f 1 -l 1 -jp2 test.pdf image 2) copy the result to image.jp2, image.j2k and image.jpt 3) j2k_to_image -i image.jp2 -o image.pgm 4) j2k_to_image -i image.j2k -o image.pgm 5) j2k_to_image -i image.jpt -o image.pgm I'm reassigning this to openjpeg.
