When using Ghostscript as a file rasterizer converting PostScript or PDF to a raster image format you will of course want to specify an appropriately named file for the output.

It goes to the first directory on the list, and it’s descendants, looking for all files that appear to contain PostScript fonts also Truetype fonts ; it then adds all those files and fonts to the combined Fontmaps, and starts over. Useful only for certain specialized packages like pstotext that redefine operators.

Specifies alternate name or names for the Fontmap file. We think this problem has been fixed in Ghostscript version 6.

Subpixels are a smaller raster grid which is used internally for text antialiasing. Can you do the same thing with only 14 characters?
