GNOME Bugzilla – Bug 679651
Export to Cairo PS shows non-existent lines
Last modified: 2014-03-03 12:01:26 UTC
Created attachment 218366 [details] ZIP containing test.dia, test.ps and test.eps When certain diagrams created in Dia 0.97.2 are exported to Cairo PS the output contains lines that do not exist in Dia canvas. If the diagram is exported to Encapsulated PS the extra lines do not exist in the output. This can be shown in the attached files: test.ps contains a vertical blue line that does not exist in the diagram. (It seems this bug is similar to bug 587967 which says the problem exists in various output formats but I see it only in Cairo PS.) -- rpr.
I can reproduce this with Dia master and the cairo PDF backend - but only when using the cairo 1.10.2 (on Gentoo/64). With cairo 1.10.3 on XP it works as expected. I have now idea how to work around this - so your best option seems to be to check with an updated cairo version.
Considered to be an intermediate glitch with cairo, closing. I don't see what could be done in Dia to work around this.
It's true that the issue doesn't exist with newer cairo backend, e.g. I tested it on a Debian with libcairo 1.12.16. But, Windows version of Dia 0.97.2 (http://dia-installer.de/download/index.html) comes with cairo 1.10.2 integrated and the issue is present. It would be nice to have that installer updated with a newer cairo lib. Or you think that Windows users should update cairo lib on their own? Is there a hint about that? (Sorry for posting this here on Gnome Bugzilla.) -- rpr.
