leRiCl YaBB Newbies Offline Posts: 24	how do I make an image and save it? Nov 12th, 2007, 12:18pm   how do I make an image copying the canvas, without using "loadImage()" ? (eg scenario: Drawing a rectangle, copy the canvas into a PImage, and then display the PImage instead to save processor time. I have lots of these vector shapes and it'd be much faster if I can imprint them as images and displaying them as bitmaps.)
