When I wrote advanced definitive OpenType shaping rules for Malayalam and build scripts based on FontForge, I also wanted to reuse the comprehensive shaping rules in all the fonts RIT develop. It has excellent scripting abilities, especially Python library to manipulate fonts which I extensively use in producing & testing fonts. registerMenuItem( partial( g.FontForge is the long standing libre font development tool: it can be used to design glyphs, import glyphs of many formats (svg, ps, pdf, …), write OpenType lookups or integrate Adobe feature files, and produce binary fonts (OTF, TTF, WOFF, …). set_classname, i = 4), None, pr, ( "Font", "Glyph"), None, "Guess Anchors", "Set class names…",įontforge. set_classname, i = 0), None, pr, ( "Font", "Glyph"), None, "Guess Anchors", "Set class names…",įontforge. set_classname, i = 1), None, pr, ( "Font", "Glyph"), None, "Guess Anchors", "Set class names…",įontforge.
