The tiffcrop is inverting RGB and YCbCr output when using jpeg compression.
The stated YCbCr default (no format specified) works correctly: 'tiffcrop -c jpeg infile.tiff outfile.tif' the output is a YCbCr file (default behavior) 'tiffinfo outfile.tif' 'Photometric Interpretation: YCbCr' But if we request a specific mode using the proposed 'rgb' and 'raw' jpeg options: 'tiffcrop -c jpeg:raw infile.tiff outfile.tif' the output is a RGB file 'tiffinfo outfile.tif' 'Photometric Interpretation: RGB color' 'tiffcrop -c jpeg:rgb infile.tiff outfile.tif' the output is a YCbCr file 'tiffinfo outfile.tif' 'Photometric Interpretation: YCbCr' When we request RGB a YCbCr file is produced, when YCbCr is requested a RGB file is produced. This has been reported 2 years ago as Issue #228, but still not addressed. Is this considered of lesser importance? I would certainly fix it if I knew how to do it... I know that the work on libtiff is voluntary, which I very much appreciate and am grateful for. I just thought I would leave a reminder here, in case the issue had just been inadvertently buried in time. tiffcp does not suffer from this drawback. _______________________________________________ Tiff mailing list Tiff@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/tiff
