BackgroundImage

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.

// @pjs preload must be used to preload the image so that it will be available when used in the sketch  

/* @pjs preload="data/milan_rubbish.jpg"; */



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("data/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);
