As I stated earlier in the thread. FontConfig has it right -- provides
this information. Which makes me wonder even more why the application
level stuff doesn't get it right.
It isn't 100% yet, I did find one error:
For Helvetica (Type1), the" "fonts.cache-1" file lists:
"hvc_____.pfb" 0 "Helvetica:style=Condensed \
"hvn_____.pfb" 0 "Helvetica:style=Narrow:slant=0:weight=100:width=100:
"hv______.pfb" 0 "Helvetica:style=Regular:slant=0:weight=100:width=100:
so I appear to have found one minor error. I'm not certain what the
width for Helvetica Narrow should be but it would obviously be between
75 and 100.
Do you think that FontConfig should address the problem with TrueType
fonts where with Type1 the family name for Helvetica Narrow is:
but with Type1 it is:
Yes MicroSoft is responsible for the fact that TrueType names are
broken, but we really need them to match in *NIX. I find that many apps
are built for the TrueType model :-( so I don't really know which way it
would be better to convert. Perhaps the cache file could do it both ways.
Also note: "style=Condensed Medium" above. Some of the AFM files have
errors in them -- this one for example. It should really be:
"style=Condensed" but the fault lies in the AFM file. Should
FontConfig attempt to fix this?
Note I like your product (keep up the good work!), but I am a retired
engineer and am advising you of the minor issues I found to try to help.
That is what engineers are taught to do, find the fault in stuff.
That is the first step in improving something.
