convfont fontfile fontheight vgafontfile
A binary font file of any number of characters up to 256 can be used, although at least defining the first 128 characters is a good idea. The fontheight must be in the range 1 - 32.
The fontfile file consist of fontheight bytes stored sequentially (top to bottom) for each character in your font, starting with the character with code 0.
The format of vgafontfile is that required by restorefont(1) and described there.
This utility is part of svgalib and can be found in the utils/ subdirectory of the original svgalib distribution. However, it is not installed by default, s.t. it is unclear where you can find it if your svgalib was install linux distribution.
In case of any such problem, simply get an svgalib distribution from the net. You don't need to install it. Just make in the utils/ subdirecty. As of this writing, svgalib-1.2.12.tar.gz is the latest version and can be retrieved by ftp from sunsite.unc.edu at /pub/Linux/libs/graphics and tsx-11.mit.edu at /pub/linux/sources/libs which will most probably be mirrored by a site close to you.

This manual page was edited by Michael Weller <eowmob@exp-math.uni-essen.de>. The exact source of the referenced utility as well as of the original documentation is unknown.
It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
