Best way to preserve the background
Mar 29th, 2009, 10:12pm  
Hi,

I was wonder what the best (most efficient processor wise) way to preserve a background layer would be.

For example, if I made a simple paint program that had custom cursors that I was drawing on the screen, I'd want to be able to leave the background alone, aka not clear it next frame with a call to background.

The only way I know how to do this now is to capture the screen with get() and put it into a PImage before drawing the stuff that I want to move next frame, like UI stuff.

Any clues?

I am not too sure of what is the problem. But if you want to paint over a fixed background, indeed you can load an image (or create it) and do image() at start of draw() to restore background. If you need to preserve painting as well, you can just draw on another PImage and image() it over the background.
