Hello.
I see three ways to add BDF and PCF support to the FreeType library:
1- Use the xc/lib/font/bitmap code of XFree86.
Advantages: Once the wrapper has been written, we get support for both
BDF and PCF font format.
Flaws: X does not rely on the Adobe BDF specification version 2.2.
For instance, it does not include METRICSET 1 (that is, vertical
writing). I have to figure out how much work is required to
compile X bitmap library as stand-alone.
2- Use the excellent Mark Leisher BDF library.
Advantages: It fully complies Adobe 2.2 specification (am I right?),
deals with many different PROPERTIES, performs error
correction on malformed BDF file, and so on.
(Minor) Flaws: Quite huge library. Missing PCF support.
3- I can write /ex-novo/ the two drivers.
Advantages: The code will take advantage of the framework provided by
the FreeType library (streams, for instance) and of the
"small is better" philosophy.
Flaws: It will take some time to me writing (and proving them correct)
both the drivers.
I am looking for your opinions: both X and FreeType developers welcomed.
