JPEG Screen Saver 1.00

Disclaimer

JPEG Screen Saver is free. You may use it and copy it (in its original archive) as much as you like. You may NOT change it in any way. The program is distributed as is. I take no responsibility whatsoever if it doesn't work, if it hangs your system, or if it causes any other kind of damage. To put it simple - you use this program at your own risk.

Introduction

A few years ago, I wrote a screen saver using Borland Pascal. It would display all the picture files in a specified directory using a simple display effect. The program was capable of handling only Windows BMP files. Since I used mainly truecolor pictures they took up a lot of precious disk space. The solution was to use JPEG files instead of BMP files.

I began using Delphi and needed a simple project to get me started. Writing a simple screen saver seemed like a good idea. The screen saver should work like my original BP program. It should also be able to handle JPEG files, and include a few more display effects.

This program was written in Delphi 1.0.

Credits

This program makes use of the following components:

My many thanks to these guys for making their code public (and free!).

Instructions

Simply copy the .scr file into your Windows System directory (or the Windows directory). Then run the Control Panel to change screen saver. The first time you should activate the Setup dialog. The options are pretty straightforward and should be self-explanatory.

Known limitations and bugs

This is a first test version of the program.

The TJPEGImage component doesn't handle every possible aspect of the JPEG file format. It should work with most files though.

The TFXImage component has a few bugs. I haven't made any effort to solve them yet.

I'm not sure if the program requires some DLL:s included in the Delphi package.
