printftest(6)                 Svgalib User Manual                printftest(6)

       printftest - tests the vgagl gl_printf function

       printftest x y

       This  test  utility reads keys from the keyboard and displays them on the screen at pixel position (x, y) using
       gl_printf(3).  It must be linked with the ELF svgalib libraries.

       You can set a videomode to use by setting the environment variable SVGALIB_DEFAULT_MODE to a number (see  vgat-
       est  for  a  list)  or a string like G0x1x2 where you replace 0 with desired x resolution, 1 with the desired y
       rez, and 2 with the desired number of colors (2, 16, 256, 32K, 64K, 16M, 16M4). Again, only certain choices are
       available, see vgatest for a list.

       In case nothing is selected, G320x200x256 is choosen.

       This  demo is part of svgalib and can be found in the demos/ subdirectory of the original svgalib distribution.
       However, it is not installed in the system by default, s.t. it is unclear where you can find it if your svgalib
       was  installed by some linux distribution. Even then, when you have the demo on your system, you probably won't
       have the sources s.t. it is only of limited use for you.

       In case of any such problem, simply get an svgalib distribution from the net. You even don't  need  to  install
       it. Just make in the demos/ subdirecty. As of this writing, svgalib-1.2.12.tar.gz is the latest version and can
       be   retrieved   by   ftp   from   at   /pub/Linux/libs/graphics   and    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 <>. The exact source of the refer-
       enced demo 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 <>.

       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.
