scrolltest(6) Svgalib User Manual scrolltest(6)NAMEscrolltest - tests some scrolling algorithms with svgalib
SYNOPSISscrolltestDESCRIPTION
Smooth scrolling demo. Uses three different techniques. Useful for
testing Mode X functionality (not that I would recommend it over
320x240x256 linear). Press <Space> to cycle through the demos.
The demos works only in 320x240x256 for the first 2 tests and with
320x200x256 in the last. Demos 1 & 3 use a virtual screen buffer, mode
2 (jumpy) works on screen. This is more a skeleton if you want to write
some animation program, rather than a nice demo.
Shows frames per second (multiplied by 10) for method 1 & 3. Thus works
also a kind of memory speed tester
This demo is part of svgalib and can be found in the demos/ subdirec‐
tory 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 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-

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.
