Re: drawing text and GdkPixbuf

[Lauris Kaplinski <lauris ariman ee>]

The best solution very much depends on how much and what kind of text you
need. Possible alternatives are:

* Use X font -> bitmap -> image conversion. For last render you can
probably also use art_rgb_bitmap_affine, if you need affine and do not
need alpha. X fonts are surely most standard, but the API sucks, and
they can only be obtained in raster

* If you prefer using Gnome Type1 fonts, take GnomeFont/GnomeFontMap, get
ArtBpath, convert to SVP and render this to buffer. If Gnome
(gnome-print) is installed, you can usually count, that standard (Times
etc.) Type1 fonts are also available.

* If you dare, you can use FreeType to render TTF fonts into graymaps, and
overlay these to buffer, or convert TTF outlines to ArtBpath and render
these via SVP-s. Unfortunately you cannot guess anything about available
TTF fonts in user system.
