testgl(6) Svgalib User Manual testgl(6) NAME testgl - test the vgagl library SYNOPSIS testgl DESCRIPTION Demo program for vgagl(7) framebuffer library. Runs in any mode preset from the environment. First draws pixels in random locations, then random boxes, then random lines and finally some bit image in random locations (all just over the previous drawings). Then the test is repeated clipping the screen output to a smaller screen portion (using a vgagl(7) function). Finally a (lousy) 'rotating' linux logo is shown in the top left quadrant and then is drawn over the whole screen. Depending on internal development state of svgalib, it may use an accelerator for some of the functions. You can set a videomode to use by setting the environment variable SV- GALIB_DEFAULT_MODE to a number (see vgatest 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 sys- tem 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 lim- ited 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 sunsite.unc.edu at /pub/Linux/libs/graphics and tsx-11.mit.edu at /pub/linux/sources/libs which will most probably be mir- rored by a site close to you.

The exact source of the referenced 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 <H.Hanemaayer@inter.nl.net>. Occasionally this might be wrong. I hereby asked to be excused by the orig- inal author and will happily accept any additions or corrections to this first version of the svgalib manual. Svgalib 1.3.0 8 April 1998 testgl(6)
