Description Josh Parsons 2005-05-20 14:30:03 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.0.4-1.3.1 Firefox/1.0.4

Description of problem:
Trying to create partially transparent images with pnmtopng causes a segmentation fault.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
ppmmake '#ffffff' 2 2 |pnmtopng -trans '#ffffff' >img.png

Actual Results:  pnmtopng: 1 colors found
Segmentation fault

Expected Results:  pnmtopng: 1 colors found

(and a transparent image written to img.png)

Additional info:

This breaks latex2html.

I was able to workaround it by substituting the pnmtopng binary from an older release of netpbm-progs, so the problem must be with the binary, not the netpbm libraries.

Comment 1 Jindrich Novy 2005-05-23 11:22:51 UTC
Josh, this is a known issue with netpbm-10.25-2 we have in FC3. The recent
version of netpbm-10.27 doesn't suffer from this issue. I'll release an update
for FC3.
