How do I make Dia use PostScript fonts instead of Pango rendering?
The current PostScript output on systems with font-config involves rendering the fonts as bezier curves. This gives an (almost) perfect output, but doesn’t allow PostScript tools to operate on the fonts. If you want to get output using PostScript fonts, use the EPS export filter marked as “using PostScript Latin-1 fonts”. To use this from the command line for conversions, add –export-to-format=eps-builtin to the command line. Note that this export doesn’t support other encodings than Latin-1, and the text size may be somewhat off. Please don’t ask us to add other encodings to this. We will not do it. It’s an interim solution while we try to get embedded fonts out of Pango (maybe using PangoPDF).
