NAME

6       scrolltest - tests some scrolling algorithms with svgalib

SYNOPSIS

9       scrolltest

DESCRIPTION

13       Smooth  scrolling  demo.  Uses  three  different techniques. Useful for
14       testing Mode X functionality  (not  that  I  would  recommend  it  over
15       320x240x256 linear). Press <Space> to cycle through the demos.
16
17       The  demos  works  only  in  320x240x256 for the first 2 tests and with
18       320x200x256 in the last. Demos 1 & 3 use a virtual screen buffer,  mode
19       2 (jumpy) works on screen. This is more a skeleton if you want to write
20       some animation program, rather than a nice demo.
21
22       Shows frames per second (multiplied by 10) for method 1 & 3. Thus works
23       also a kind of memory speed tester
24
25       This  demo  is part of svgalib and can be found in the demos/ subdirec‐
26       tory of the original svgalib distribution. However, it is not installed
27       in  the  system by default, s.t. it is unclear where you can find it if
28       your svgalib was installed by some linux distribution. Even then,  when
29       you  have  the demo on your system, you probably won't have the sources
30       s.t. it is only of limited use for you.
31
32       In case of any such problem, simply get an  svgalib  distribution  from
33       the  net.  You  even  don't need to install it. Just make in the demos/
34       subdirecty. As of this writing,  svgalib-1.2.12.tar.gz  is  the  latest
35       version   and   can   be  retrieved  by  ftp  from  sunsite.unc.edu  at
36       /pub/Linux/libs/graphics and tsx-11.mit.edu at  /pub/linux/sources/libs
37       which will most probably be mirrored by a site close to you.
