image alpha Jun 10th, 2010, 4:39am   Hi, I try to run this example from the code reference : http://processing.org/reference/PImage_alpha_.html Code: PImage img = loadImage("test.jpg"); PImage alphaImg = loadImage("mask.jpg"); img.alpha(alphaImg); image(img, 0, 0); image(img, 25, 0); I've loaded two images with the same width/height. I get the following error : The function alpha(Pimage) does not exist. Same goes when I make a pixel array with loadPixels. The function alpha(int[]) does not exist. Is this code not supported anymore ?
