I would suggest modeling your work after the ext_cairo and ext_qt drivers, creating new drivers called (perhaps) "ext_pdf" and "ext_wingcc". These would be share many functions with the pdf and wingcc drivers, but would have different init, eop and tidy methods. In examples/c there is file called ext-cairo-test.c that provides a simple example of how to use the ext-cairo device. In the drivers folder there is documentation describing how to create new drivers (README.drivers). > I have also added an command line option to set the pdf driver resolution, > as the current driver assumes a 50" x 37.5" surface and scales it to the > output, which becomes distorted if the output aspect ratio is not 4x3.

Sending patches to this list is fine. -Hazen ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ Plplot-devel mailing list Plplot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/plplot-devel
