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.
y = 0 def setup(): size(640, 360) # The background image must be the same size as the parameters # into the size() method. In this program, the size of the image # is 640 x 360 pixels. global bg bg = loadImage("moonwalk.jpg") def draw(): global y background(bg) stroke(226, 204, 0) line(0, y, width, y) y += 1 if y > height: y = 0
