Description Jack Moffitt 2003-07-31 08:56:39 UTC
The attached customer file has stripes when viewed with the display device or
with tiff24nc.

I have reproduced with CVS HEAD with the following commandlines:
gs 64_agony_lay.pdf
gs -sDEVICE=tiff24nc -r180 -dNOPAUSE -dBATCH -sOutputFile=test.tiff 64_agony_lay.pdf

Comment 2 Alex Cherepanov 2004-05-11 12:23:22 UTC
This problem was introduced with the new JPEG library, v.6b .
Before we figure out how to fix it the customer can downgrade
to the v.6a , which compiles without any changed in the
latest versions.

Additional testing notes: GS HEAD renders correctly with jpeg6a statically
linked, incorrectly with jpeg6b (Linux). xpdf segfaults. OSX Preview renders
with similar artifacts. Test file appears to be an example of a
transparency-flattened file from InDesign 2.

Proposed patch to libjpeg posted here:

The file is invalid, so this can't be considered a high priority patch. It will
probably suffice to document it and make it available to users. Of course, it
should go into the next release of libjpeg if there is one.

The archive url broke. See 

    http://ghostscript.com/pipermail/gs-code-review/2004-June/004579.html

instead.

Dropping priority to correspond with the current triage scheme.
Comment 6 Ray Johnston 2005-03-18 15:12:15 UTC
No longer a customer issue
Comment 7 Raph Levien 2005-03-30 08:36:29 UTC
Since this is an issue in libjpeg rather than Ghostscript, we are closing it here. A note has been added to 
Issues.htm:

http://ghostscript.com/pipermail/gs-cvs/2005-March/005363.html

Linux distributions in particular are encouraged to apply the patch to their system libjpeg packages.
