AFDKOs libre version doesn't include the removeOverlap() method, so you need something else to do that, and fontforge improved its version substantially last year. Fontforge also improved its UFO support, such that you can use it to develop UFO+FDK projects (like Adobe Source Sans+Serif) However, Fontforge has supported importing and exporting fea files for many years, and is scriptable for command line use. Before deciding to switch, I recommend setting up both a fontforge and fdk based workflow from the same source and comparing the resulting binaries, and also considering how maintainable and comprehensive each is. <div class="gmail_quote">On Jan 29, 2015 3:18 AM, "Pravin Satpute" <<a href="mailto:psatpute@redhat.com">psatpute@redhat.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div bgcolor="#FFFFFF" text="#000000"> Hi All, I was thinking for this from some time now. Reasons: 1. Lots of well know fonts are using AFDKO. AFAIK Adobe fonts are build using AFDKO. 2. Things we required in Lohit specifically, easy to read feature files and final ttf with Adobe glyph naming guideline looks easily manageable with AFDKO. (GlyphOrderAndAliasDB and .Fea) 3. AFDKO feature file compilation is much better than Fontforge. Noticed this earlier with OTM errors. Also while compiling i found number of error not identified by fontforge. 4. All command line, so we can automate very nicely. 5. We will use fontforge only for outline related work. Presently we are still using fontforge for OpenType rules writing, i have not faced any problem into it yet. But perfect solution is we should write open type rules in .fea file itself. This at least not targeting presently Regards, Pravin Satpute </div> _______________________________________________ Lohit-devel-list mailing list <a href="mailto:Lohit-devel-list@redhat.com">Lohit-devel-list@redhat.com</a> <a href="http://www.redhat.com/mailman/listinfo/lohit-devel-list" target="_blank">http://www.redhat.com/mailman/listinfo/lohit-devel-list</a> </blockquote></div>
