Package: libopenjp2-tools Version: 2.1.0-2 I can generate an invalid file using kakadu 7.6:
wget -c http://www.ece.rice.edu/~wakin/images/lena512color.tiff kdu_compress -i lena512color.tiff -o lena1024x1024.jp2 Sdims="{1024,1024}" Stiles="{512,512}" -frag 0,0,1,1 Creversible=yes -no_info -quiet Clayers=5 Clevels=3 kdu_compress -i lena512color.tiff -o lena1024x1024.jp2 Sdims="{1024,1024}" Stiles="{512,512}" -frag 0,1,1,1 -rotate 180 Creversible=yes -no_info -quiet Clayers=6 Clevels=2 kdu_compress -i lena512color.tiff -o lena1024x1024.jp2 Sdims="{1024,1024}" Stiles="{512,512}" -frag 1,0,1,1 -rotate 180 Creversible=yes -no_info -quiet Clayers=7 Clevels=5 kdu_compress -i lena512color.tiff -o lena1024x1024.jp2 Sdims="{1024,1024}" Stiles="{512,512}" -frag 1,1,1,1 Creversible=yes -no_info -quiet Clayers=8 Clevels=4 Which leads to: $ opj_decompress -i lena1024x1024.jp2 -o bla.tif [INFO] Start to read j2k main header (111).

This problem can arise if empty packets are used (i.e., packets whose first header bit is 0) and the value coded by the inclusion tag tree in a subsequent packet is not exactly equal to the index of the quality layer in which each code-block makes its first contribution. Such an error may arise from a mis-interpretation of the standard. The problem may also occur as a result of a corrupted code-stream. Try re-opening the image with the resilient mode enabled. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
