I am running NetBSD 7.0 amd64. For a long time I have been facing poor quality pdf output (poor resolution fonts with pixels appearing) from the "Print to File" dialog of firefox. I somehow thought it was firefox problem.
But today I installed graphviz from pkgin repository and find the same issue with pdf produced using graphviz. I noticed "Creator" property of pdf to be "cairo" and hence upgraded cairo to 1.14.6, latest in pkgin repository. Still the problem persists. Both firefox and graphviz used to work fine for me a while back. So I think the problem is due to either a common component they use or may be some missing fonts etc. Please advise. Mayuresh.
