Description Andrew Schretter 2007-01-08 22:36:51 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.9) Gecko/20061219 Fedora/1.5.0.9-1.fc6 Firefox/1.5.0.9

Description of problem:
My users have figures generated by gnuplot that render correctly
in some versions of ghostscript (notably ghostscript-7.07-41 from
Fedora Core 4) but are slightly off in ghostscript-8.15.3-1.fc6.

Attached are 3 files, the original postscript code, a png of the
proper rendering from 7.07-41 and a png of the improper rendering
from 8.15.3-1.fc6.  The proper rendering should show the curve intersecting
the two points on the x-axis.  The incorrect rendering has the curve just
missing the second point.

I also tested with ghostscript-8.15.2-8.1 and got different but still
incorrect results.  Testing with real ghostscript sources, 8.01 worked,
8.10 does not.

Version-Release number of selected component (if applicable):
ghostscript-8.15.3-1.fc6

How reproducible:
Always


Steps to Reproduce:
1.View postscript file in ghostscript-8.15.3-1.fc6
2.
3.

Actual Results:
Postscript was displayed incorrectly, curve did not intersect points
on X-axis

Expected Results:
The rendered postscript curve should have intersected the 2 points on the
X-axis

This renders correctly with Fedora 8 (ghostscript-8.62-3.fc8).
