type FontLoader = [Either FontDef FontFamily] -> IO FontLoadResultSource
A FontLoader is an action from a list of fonts to a
FontLoadResult returned in IO.
Fonts are supplied in a list of Either FontDef FontFamily,
this is a little cumbersome but it allows the loader to load
individual fonts and / or a whole families with a single API
call.
simpleFontLoader :: (FontLoader -> IO a) -> IO (Maybe a)Source
Tries to find the GhostScript metrics first...
Runs the IO action on the loader if it finds one.
Either of one of the environment variables
WUMPUS_AFM_FONT_DIR or WUMPUS_GS_FONT_DIR must be defined
and point to their respective directory.
