Description Thomas Sailer 2004-06-06 23:26:41 UTC

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.

Comment 1 Thomas Sailer 2004-06-06 23:35:10 UTC

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.
