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.
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.
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.
Fixed with the merging of pattern_clist_branch.
