Description Chris Liddell (chrisl) 2010-11-10 19:05:07 UTC

The file stars.pdf from:
http://bugs.ghostscript.com/show_bug.cgi?id=691755

When rendered with GS shows only one image of a star at the top of the page, where it should contain 6 spaced across the page.

A simple:
./gs -sDEVICE=pnmraw -o output/stuff%03d.pnm -r150 -dBATCH -dNOPAUSE stars.pdf

shows the problem.


By disabling transparency all the stars get drawn, but obviously without the "effects".

Created attachment 6892 [details]
cut down example

These files are not easy to cut down, due to their (really bad!!) construction. Since I was half way there, I cut it down to just one case of the missing star problem.

It just might same someone time.

Thanks Chris for doing that.

Comment 3 Michael Vrhel 2010-11-19 21:46:28 UTC

OK. This file is insane.  Likely a pattern with transparency issue.  Now getting back to work on my fix so that large patterns can be handled as clists.

Comment 4 Michael Vrhel 2010-11-20 00:39:16 UTC

OK.  So my fix for doing the transparency tiles with clist fixes this.  I need to do a bit of regression testing on this, since it is a pretty big change.

Comment 5 Robin Watts 2011-07-19 20:17:55 UTC

Fixed with the merging of pattern_clist_branch.
