scrolltest(6)		      Svgalib User Manual		 scrolltest(6)

NAME
       scrolltest - tests some scrolling algorithms with svgalib

SYNOPSIS
       scrolltest

DESCRIPTION
       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.

AUTHOR
       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 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.
