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  lin-
     ear). 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/ 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.

     documentation is unknown.

     It is very likely that both are at least to some extent  are  due	to  Harm
