I'd like to search the fonts on a system by family name, but prefer
outline fonts later on the list over bitmap fonts earlier on the list.
For example, for the spec "Courier, DejaVu Sans Mono":
1. Courier (outline)
2. DejaVu Sans Mono (outline)
3. Courier (bitmap)
4. DejaVu Sans Mono (bitmap)
5. Fallback font
Here's what I've tried:
1. I tried figuring out how to do this with a single call to
FcFontMatch. It turns out the "best" match is determined by hardcoded
weights. If they weren't hardcoded, I could simply increase the
weight for the "outline" attribute.
2. I tried figuring out how to do this passing each family separately
to FcFontMatch, then picking the first that has an outline, or falling
back to the first without an outline. However, I can't figure out how
to tell the difference between when FcFontMatch returns a family I
asked for and when it returns a fallback font.
3. I tried using FcFontList to create a font list containing only
outline fonts so I could search that first, but I can't tell the
difference between when it can find a font and when it found a
fallback font.
4. I tried looking at the source code to FcFontMatch, but it looks
like it does a lot of peeking inside of structures that are opaque to
clients. I'd have to make a lot of API calls to access the required
information.
What am I missing, or is it really that hard to do this?
