This example presents the fastest way to load a background image into Processing. To load an image as the background, it must be the same width and height as the program.
Original Processing.org Example: BackgroundImage
// All Examples Written by Casey Reas and Ben Fry // unless otherwise stated. PImage bg; int a; void setup() { size(200,200); frameRate(30); // The background image must be the same size as the parameters // into the size() method. In this program, the size of "milan_rubbish.jpg" // is 200 x 200 pixels. bg = loadImage("milan_rubbish.jpg"); } void draw() { background(bg); a = (a + 1)%(width+32); stroke(226, 204, 0); line(0, a, width, a-26); line(0, a-6, width, a-32); }
