Is there a way to use images in your processing program that have been taken from the program,ie saveFrame and put it back in as loadImage--from what I found you can only save it in .tif, but you can only load in .gif or .jpg.

thanks!

you can also save and load targa files (.tga)

However, (using v 114, OS X) saved targa format not recognized on way back in. Anyone able to get this to work?

Well the update solved that problem! Thank you--
I was wondering if anyone knows how to get around this:
I am capturing the image created by the program at mousePressed and feeding it back in as the background at mouseReleased, however, even though mousePressed comes first, it says that the image doesnt exist yet when it's supposed to be fed back in. Is there a way to slow it down, or a better way of feeding it back in other than using mouseReleased? Can you say mousePressed two times or something?
thanks!

try this:

Code:

PImage bg;

void setup() {
  size(400, 400, P3D);
  bg = new PImage(width, height);
  stroke(255);
}


void draw() {
  background(bg);
  line(width/2, height/2 , mouseX, mouseY);
}


void mousePressed() {
  bg.copy(g, 0,0,width,height,0,0,width,height);  
}


obviously if you move the background(bg) to void mouseReleased() it'll do exactly as you asked, but for this demonstration nothing would really be visible doing it that way.
