In my perception, pango requires actual font file (.otf, .pfb etc.). If there is no font files, pango can't render anything. Even if there is only font metric files (.afm, .pfm, .tfm etc.), pango can't handle it.
Moreover, in my experiment, pango can't handle the ligature of PostScript Type1 font (.pfb with
.afm or
.pfm). It can handle the ligature of OpenType font (.otf).
What a mess. Well, since we do the font handling with Pango, we have to make do with its limitations. I'd have thought that a sensible Pango design would have gotten by with at most a .afm file for producing PostScript files without embedded fonts but using PostScript standard fonts. If that's not the case, and if we even need to provide a .otf font, I don't see much of an option around using a free font like Nimbus. https://codereview.appspot.com/224800043/ _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
