Component 1 contains only 32768 blocks while component 0 has 65536 blocks openslide-write-png: Error decoding tile. Component 1 contains only 32768 blocks while component 0 has 65536 blocks Version-Release number of selected component (if applicable): openslide-tools-3.2.6-1.el6.x86_64 openjpeg-libs-1.3-10.el6_5.x86_64 How reproducible: always Steps to Reproduce: 1. 2. 3. Actual results: Expected results: works as expected with openjpeg-libs-1.3-9.el6_3.x86_64 Additional info:
Reassigning to openjpeg. The OpenJPEG patch for CVE-2013-6045 disables decoding of images whose first color component has a higher resolution than subsequent components. This is a legitimate image encoding; consider, for example, YCbCr images with chroma subsampling. This change is preventing OpenSlide from decoding certain Aperio slide files (example slide at [1]). For example, consider p0_06.j2k from the OpenJPEG test suite [2]. With 1.3-9.el6_3: $ j2k_to_image -i p0_06.j2k -o out.ppm [INFO] tile 1 of 1 [INFO] - tiers-1 took 0.020997 s [INFO] - dwt took 0.002000 s [INFO] - tile decoded in 0.027995 s PNM CONVERSION: Truncating component 0 from 12 bits to 8 bits PNM CONVERSION: Truncating component 1 from 12 bits to 8 bits PNM CONVERSION: Truncating component 2 from 12 bits to 8 bits PNM CONVERSION: Truncating component 3 from 12 bits to 8 bits Generated Outfile out.ppm With 1.3-10.el6_5, the same command produces: [INFO] tile 1 of 1 [ERROR] Error decoding tile.
