ONDABLANKER VERSION 1.0 - (c) 1998 by Luigi Paolo Galli


DESCRIPTION
Ondablanker is a simple screen blanker designed for Windows 95; it has been
written mainly to practice in Delphi and Win32 programming but also to have 
a much more pleasant screen blanker than the ones that I got with my Win95 
and Plus CDs. Ondablanker will draw a set of animated points or lines on the 
screen, the animation is driven by sine/cosine mathematical functions.
The control panel allows you to change the calculation parameters to obtain
several different kinds of animations.


LEGAL TERMS
Ondablanker is FREEWARE. 
This software is provided AS IS, the author is not responsible for any kind

PROGRAMMING JOBS
I am interested in programming jobs, esp. in the Amsterdam area where I am 
going to move in a few months. If you need a programmer please contact me! 
See my home page HTTP://www.angelfire.com/me/galli for more details.


CONTRIBUTIONS / FEEDBACK
Ondablanker is distributed free of charge, it's 100% freeware; but I always 
like to receive comments, suggestions and non desctructive criticism!
An e-mail from you would be most appreciated.


INSTALLATION
Copy the file called ONDABLANKER.SCR to your windows directory, then select
it from the screen saver list of your display properties dialog accessible
through the control panel.


CONFIGURATION
Just play with the parameters, the 'preset combinations' combo box offers
some examples.


TECHNICAL NOTES
Being mainly an exercise of Delphi and Windows programming Ondablanker 
is not extremely optimized for speed, all the sines are real time 
calculated for every point; the screen is updated simply through the
TCanvas methods and properties that Delphi 3.0 offers.
I might consider to write some optimal code for the calculations but it's
not a priority by now. I don't know how and if it can be done but the 
use of DirectX could significantly improve screen update performances;
maybe, if I will get my hands on a DirectX unit for Delphi ;-).
