Hmm. Looking at it, it provides the mapping of the orig bluesky type1 fonts, not that of the bakoma ones. Why can't lyx use that and the bluesky fonts natively?... Anyway I decided I was beaten on the path of trying to automagically convert the bluesky fonts to ttf ones that look like bakoma's. And having already spent about 20 hours on that, I decided I could spare another hour or two doing the same thing by hand. So I've taken the bakoma fonts, removed all glyphs, and copied over the bluesky glyphs, changing the font properties as needed. In the end nothing remains of the bakoma version but the way the characters are arranged, which is what we want. This should be ok wrt bakoma's copyright (IANAL)... This is still WIP due to issue #2 below, but since I'm prolly not going to do anything more with this today, I wanted to update the list. The fonts are at http://cvs.gentoo.org/~danarmak/fonts-v2.tar.bz2 - testing appreciated (last time it took about 10 minutes for the big problems to be found, but this time I've tried to do better testing). Known issues: 1. Quality loss: tolerable for on-screen editing (imo at least). Details: I converted the glyphs from postscript to truetype. That's apparently a lossy conversion (unlike the other way around) - which I only found out when it was too late. I converted to opentype (which has the same spline format as type1) which recovered most of the quality (but is still worse than the printed bluesky). So it looks worse than the bakoma stuff (due to the lossy conversion I suppose), but tolerable for editing (as long as you don't write too many formulas :-). Probably something could be done if I started all over again... (The font is also smaller than the bakoma one - try using a bigger fontsize. Can we get a separate fontsize setting for the mathed?) Also, the hinting went mad for some reason and most chars were over-hinted into smudged oblivion. I told pfaedit to remove all hints/instructions and autohint. Now it's usable - but I probably lost some of the custom hinting instructions that make bluesky look good (in particular most of the Latin alphabet in cmr10 had custom stuff). Again, tolerable (for me) since this is just for editing. 2. Some chars won't draw - lyx displays a square instead. This is the major thing left to be fixed. Looking at the kappa char for example (from cmmi10), every other char in the font draws OK and AFAICS there's absolutely no difference between it and the bakoma one, in the kappa char's properties or otherwise. I really don't know what to do about this kappa problem... A full list of the problematic chars: \leq \kappa \circleddash \nleqq \upuparrows 3. At some point the characters lost their names and got the names of the unicode characters at their encoding positions instead. This doesn't affect lyx which draws by encoding value not name (I wish I'd known that sooner), but it makes further editing of the fonts icky. If there's sufficiently good reason, I can create them again, and hopefully keep the names that time. 4. There are still no eufm10 and wasy10 fonts, because there aren't such bakoma fonts (maybe they are in the bigger bakoma collection on ctan though). However AFAICS lyx doesn't need/use these fonts anywhere? I tested all the characters listed in the matheditor float and they were present without these fonts (except for the ones from issue 2 above, and they got drawn as squares and not written in red, so they must be from the existing fonts as well). - -- Dan Armak Gentoo Linux developer (KDE) Matan, Israel Public GPG key: http://www.gentoo.org/~danarmak/danarmak-gpg-public.key -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQE+iZqMUI2RQ41fiVERAjNRAJ4sp8d1ld7StP838ZQDyreQVSD1ZgCbBoZI 6grXoK17v5YZubRNfpVHpdA= =WV20 -----END PGP SIGNATURE-----
