.TH scrolltest 6 "29 July 1997" "Svgalib (>= 1.2.11)" "Svgalib User Manual"
|
||
|
|
.SH NAME
|
||
|
|
scrolltest \- tests some scrolling algorithms with svgalib
|
||
|
|
.SH SYNOPSIS
|
||
|
|
|
||
|
|
.B scrolltest
|
||
|
|
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Smooth scrolling demo. Uses three different techniques. Useful for
|
||
|
|
testing Mode X functionality (not that I would recommend it over
|
||
|
|
320x240x256 linear). Press
|
||
|
|
.B <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
|
||
|
|
.I demos/
|
||
|
|
subdirectory 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
|
||
|
|
.B make
|
||
|
|
in the
|
||
|
|
.I demos/
|
||
|
|
subdirecty. As of this writing,
|
||
|
|
.I svgalib-1.2.12.tar.gz
|
||
|
|
is the latest version and can be retrieved by ftp from
|
||
|
|
.IR "sunsite.unc.edu" " at " "/pub/Linux/libs/graphics"
|
||
|
|
and
|
||
|
|
.IR "tsx-11.mit.edu" " at " "/pub/linux/sources/libs"
|
||
|
|
which will most probably be mirrored by a site close to you.
