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-es-
       sen.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.
