Description of problem: convert x.tiff y.jpg writes a broken JPEG image. The image is mostly black, with some non-black scanlines. Version-Release number of selected component (if applicable): broken: ImageMagick-5.5.7.15-1.3 ImageMagick-5.5.6-5 ok: ImageMagick-5.4.7-10 How reproducible: always Steps to Reproduce: 1.find a 24bit RGB TIFF file 2.run convert x.tiff y.jpg 3.watch y.jpg with your favorite jpeg viewer (or even ImageMagick's display) Actual results: Mostly black jpeg image with some nonblack scanlines Expected results: an image similar to the input image Additional info: The bug is in the ImageMagick library, not convert.
I just noted that it's not the writing of the JPEG file that is the problem, but the reading of the TIFF file. identify says: x.tiff TIFF 1747x2479+0+0 DirectClass 8-bit 1.4mb 0.880u 0:01
Does the problem still occur with ImageMagick 6.2 ? If yes, please attach a problematic image here.
