Description Chema Celorio 2003-01-18 19:12:47 UTC

Matching a patern with FC_SLANT_ITALIC returns a different result than the same
query if done with a FC_STYLE="Italic". 

On a system with only two fonts (or a stock Redhat8.0 system with all of its fonts):
/usr/X11R6/lib/X11/fonts/Type1/l048013t.pfa
/usr/X11R6/lib/X11/fonts/Type1/l048033t.pfa

with the default /etc/fonts/fonts.conf file from RedHat 8.0 returns a different
result with the attached code. "Oblique" is not closer than "Regular" to
"Italic" if matched with strings, with integers the expected behaviour occurs.

Sample code attached. When ran, I get this results:
[chema@lamark bug]$ ./sample
1: /usr/X11R6/lib/X11/fonts/Type1/l048013t.pfa
2: /usr/X11R6/lib/X11/fonts/Type1/l048033t.pfa
[chema@lamark bug]$ 

I've worked around this bug on my code and I don't need the fix since it seems
better to me to match by integers anyways, but I still wanted to file the bug.

FC_STYLE is nominally informative rather than instructive; attempting to perform
any kind of string "nearness" metric from the range of possible font styles
seems impractical.

Comment 3 Chema Celorio 2003-01-18 20:05:04 UTC

Then it might be a documentation bug.

man fontconfig says:
     style     FC_STYLE         String  Font style. Overrides weight and slant

reopen?
