.TH testgl 6 "8 April 1998" "Svgalib 1.3.0" "Svgalib User Manual"
|
|
.SH NAME
|
|
testgl \- test the vgagl library
|
|
.SH SYNOPSIS
|
|
|
|
.B testgl
|
|
|
|
.SH DESCRIPTION
|
|
Demo program for
|
|
.BR 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
|
|
.BR 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
|
|
.B SVGALIB_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
|
|
.I 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
|
|
.B make
|
|
in the
|
|
.I demos/
|
|
subdirecty. As of this writing,
|
|
.I svgalib-1.2.12.tar.gz
|
|
is the latest version and can be retrieved by ftp from
|
|
.IR "sunsite.unc.edu" " at " "/pub/Linux/libs/graphics"
|
|
and
|
|
.IR "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 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
