Re: [ft] In freetype how can one set font size in pt, but keep resolution independent?
Werner LEMBERG wrote: Well, the very problem is that neither TrueType nor PS fonts have the concept of a `design size'. This is something from the TeX world. Correct. In the TeX world, a font designed for 5pt output is visibly different from the same font as designed for 10pt. For instance Computer Modern (TeX's standard font) comes in no less than eight design sizes (5,6,7,8,9,10,12,17). If the effect you are after is that of choosing one different from the usual cmr10, note that on a modern system (say teTeX-3) Bluesky's Type1 fonts come in all these varieties also. I have written a png driver for the dvi format and I used to worry about this too, design sizes and suchlike. I stopped worrying once I noted that in the dvi, the correct design sizes were specified as part of the font selection. Relevant parts of a test run are: @114 DRAW CMD: FNT_DEF1 10 195060286 655360 655360 0 6 'cmmi10' FONT 10: New entry created @136 DRAW CMD: FONT_10 FIND FONT:cmmi10 400 OPEN METRICS: '/sw/tex/teTeX/3.0/texmf-dist/fonts/tfm/public/cm/cmmi10.tfm' OPEN FT FONT: '/sw/tex/teTeX/3.0/texmf-dist/fonts/type1/bluesky/cm/cmmi10.pfb' ___ Freetype mailing list Freetype@nongnu.org http://lists.nongnu.org/mailman/listinfo/freetype
[ft] Segfault in FT_Get_Name_Index, Solaris 9, FreeType 2.1.8+
I get a segfault (or bus error, sometimes) from FT_Get_Name_Index on Solaris 9, with FreeType 2.1.8, 2.1.9 and 2.2.1. FreeType 2.1.7 works fine (but there, FT_LOAD_TARGET_LIGHT does not work) Steps to reproduce: Load font, map char name d to char index. Sometimes the map returns index 0, sometimes you get: Program received signal SIGSEGV, Segmentation fault. 0xff319318 in FT_Get_Name_Index (face=0x1ed858, glyph_name=0x33548 d) at /home/jalar/build/freetype-2.1.8/src/base/ftobjs.c:2378 2378 if ( service service-name_index ) I build 2.1.7 (working) and 2.1.8 (SIGSEGV) exactly the same way: ./configure --prefix=/home/jalar; gmake (uses gcc) Am I missing some advice for Solaris here? /Jan-Åke ___ Freetype mailing list Freetype@nongnu.org http://lists.nongnu.org/mailman/listinfo/freetype

Given the line were the segfault is detected, I suppose that the value of the 'service' variable is bogus (and not NULL). Yes, but might be overwritten somewhere else, no? I don't suppose that the changes from 2.1.7 to 2.1.8 are small enough to give a hint? No, didn't think so. In GDB, could you dump the content of and send it to me, this would be a good start. I don't really know gdb well but I took a stab and did dump value services face-internal-services The result is attached.
