Graphics Question?

This is a general question, and I would just like someone to point me in the right direction here. (In other words, I'm not looking for someone to display any code :)
I'm just curious how some programs display moving graphic pictures on the screen without the background "square". In other words, I can put a black "Timage" on a screen and slide it across, but the entire "square" moves across. I'm curious how some programs show only the image, for example if it were a person walking across your screen, the screen background would show and only the person itself (without a background "square" around him) would show? Is there a particular language that is better for this type of graphics, or can someone point me towards some info on how this is done?

The technique is called BitBlt (pr: Bitt Blitting).

Search for it on the internet, and you'll drown in documentations on how to, why to etc.

You can use any language, though I'd recommend C

Hi there,
Since your messsage is in the delphi programming area, and on the other side u asked for general answer i will tell u how it can work in any good visual programming lang (delphi,vb...):
A direct answer is that u need to take an image of what u want and to fill the background of the image with - transparent - color. u can do it with any good GIF editor and get it into delphi and tell delphi to use transparent colors and walla ! the "square" isn't there anymore.
(if u want your delphi to be able to show GIF files u need to get a component for it, search for it in the net, if u want i can send u a couple, my email is firebird666@usa.net)
- E-mail me if u want the GIF or more information, this text box is small.. :_>
