I have done some investigation, and it turns out that nothing works very well with plrender any more. Here are two issues I spotted with the following test: ./x01c -dev plmeta -o test.plmeta plrender -dev psc <options> -o test1.ps test.plmeta (1) The -a option does not work correctly. For example -a 3 shrinks the plot by a uniform amount in both dimensions rather than changing the aspect ratio. This completely confirms the bug that German reported above. (2) The fonts are not working correctly. It looks like we get Hershey fonts for plrender regardless. Both these symptoms are completely unexpected since plrender should just read the metafile which essentially holds all the plplot commands and then let the PLplot library and chosen device go ahead and do their thing just like they do if you run x01c for any device other than plmeta. So I expect the weird results we are getting for plrender now are overall symptoms of some fundamental bug in plrender that has been recently introduced. I cannot imagine what that is since as far as I know we haven't had any API changes. Anyhow, plrender is part of our fundamental technology so this issue is a showstopper bug that must be fixed before our next release. Thanks, German, for drawing this issue to our attention.
