ProcessDiagramGenerator.generateDiagram platform dependent

ProcessDiagramGenerator.generateDiagram generates platform dependent images.The problem is usage of platform specific fonts. The difference is small but it differ. It is causing problems in automated tests. (I was not able to upload images)How to solve this problem? http://download.java.net/jdk8/doc

Yes, we're aware of that issue, but I'm afraid it's not something that is easily fixable…. or do you think there is an easy fix?

I have mentioned about a solution in here http://forums.activiti.org/en/viewtopic.php?f=6&t=2874
I have even created a patch for it but I didn't get a legal permission to commit to open source projects so I can't do this.

I do not know how to "define of entire font by program". And I did not find any tutorial for that.

Sure, making it pluggable would be one step … but how many people would actually do that then?
I'd like to tackle in in a general way, where people don't need to tweak anything.

Quick fix:
Different approach could be to use SVG to generate platform independent graphs. I try to implement ProcessDiagramCanvas with SVG (follow link first implementation).

I run jUnit tests on different platforms and it seems it works. e.g. PNG <-> SVG result comparison example
