OK, Progress. I now have a working "fam2font" program which is short
enough to post here:
---------------------fam2font.c------------------------------------------------
#include <stdio.h>
#include <fontconfig/fontconfig.h>
int main (int argc, char *argv[]) {
FcPattern *pattern = 0, *match = 0;
FcChar8 *file = 0;
if ((argc < 2) || !(FcInit())) return -1;
pattern = FcPatternBuild(0,FC_FAMILY,FcTypeString,argv[1],0);
FcDefaultSubstitute(pattern);
if (!(match = FcFontMatch(0,pattern,0))) return -1;
if (FcPatternGetString(match,FC_FILE,0,&file) != FcResultMatch) return -1;
fprintf(stdout,"%s\n",file);
return 0;
}
-------------------------------------------------------------------------------------
Compile with:
gcc -Wall fam2font.c -lfontconfig -o fam2font
Example usage:
gnome-font-viewer `./fam2font fixed`
gnome-font-viewer `./fam2font Times`
Those worked OK for me, but I was expecting to get a sans-serif font with:
gnome-font-viewer `./fam2font Helvetica`
instead I got the same serif font as "Times"
What are the possible font family names?
Why is "Helvetica" not matched to a sans-serif font?
