I am noticing inconsistencies in kerning between systems in the text fonts we provide (FreeSerif, FreeSans, MuseJazz in particular), and want to start a discussion here rather than IRC where it will disappear into the ether like it did in the days leading up to Beta 1 when I last looked at this.
Back then, I determined that the key to kerning on MacOS was to check OpenType (under the TrueType options); no other options seemed relevant. But the key to kerning on Linux was to *not* check that box. And in particular, the advice I now see in fonts/README.md to uncheck "Old style kern" seemed to have no bearing on anything. I ended up producing two different versions of MuseJazz - one with OpenType off (for Linux and Windows), one with it on (for Mac). I observed that FreeSerif and FreeSans seemed to also have kerning issues, but I chose not to worry about that at that time. Now that I am needing to generate updated versions of MuseJazz (I'm adding double flat and double sharp glyphs), I've had the opportunity to revisit this, and I am confused again. I find that on one of my Ubuntu systems, FreeSerif and FreeSans do *not* kern at all in my self-builds from current sources. On my other Ubuntu system as well as my Windows system, FreeSerif kerns but FreeSans does not. MuseJazz kerns on all three systems. The check I am using is the the text "Terj" which should be a good obvious case in most fonts. Serif fonts should show kerning more noticeably on the "rj" whereas sans fonts will show it more noticeably on the "Te". The one thing I know of that is different about the system where even FreeSerif does not kern is that it is running Qt 5.4 whereas the others are 5.3. No idea if that's relevant or not, but it seems it could be. I can get FreeSerif to kern on this system by regenerating it with OpenType turned off. But paradoxically to me, MuseJazz kerns on this system even when generated with OpenType left on (the default), and FreeSans won't kern no matter what I do. Regarding FreeSans, if I bring up a metrics window in FontForge and try to examing kerning info for pairs like Te, there is none. So maybe the kerning is just plain broken for that font. Anyone know anything about any of this? Anyone want to test "Terj" (or some other string where you know what you are looking for) using all three fonts on your system and report the results? chenlung reports that for him, only MuseJazz kerns on Mac. -- View this message in context: http://dev-list.musescore.org/Kerning-tp7579040.html Sent from the MuseScore Developer mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
