`wx:get-afm-path`

(wx:get-afm-path) -> string or null
Returns the current AFM directory pathname, used for getting font size information when generating PostScript files. If the directory is unknown, null is returned.
If AFM files cannot be found when a PostScript file is being generated, then text sizes will be cacluated incorrectly and will likely be drawn with an incorrect position.
