2009.11.02 17:51 "Tiffcrop test suite", by Richard Nolde
The CVS Head version includes the test suite commands for tiffcrop.
Two of the files in the set currently fail for the extract option
because the image is smaller than the dimensions of the requested
region, eg 100x100 pixels. The image dimensions for the files are
listed below. Changing the -X 100 -Y 100 arguments in tiffcrop-extract*
to -X 60 -Y 60 would allow all but the logluv-3c-16b.tif image to pass.
The libtiffpic testsuite already contains two logluv images
libtiffpic/off_luv24.tif and libtiffpic/off_luv32.tif. My testing with
the first produces a mostly white output image with two yellow squares
whereas the second one works fine. Tiffcp does the same so I suspect
the issue is in handling the logluv24 compression in the copytags
logic. I'll see if I can look into this today but I don't know much
about logluv.
