Displaying

Images can be displayed to the screen at their actual size or any other size.

NOTE: DOM security will not allow you to load images file:/// URIs. This security can be overridden in Firefox in about:config, by changing security.fileuri.strict_origin_policy to false.

Original Processing.org Example: Displaying

// 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/arch.jpg"; */

PImage a;  // Declare variable "a" of type PImage

void setup() {

 noLoop(); // rather than drawing as an animation, only call draw() once

 size(200, 200);

 a = loadImage("data/arch.jpg"); // Load the images for use in the sketch 

} 

void draw() {

 image(a, 0, 0); // // Display the image at point (0,0) with natural width and height 

 image(a, width/2, 0, a.width/2, a.height/2); // Display the image again, this time starting at (width/2, 0), and scaled to 50% in both x and y direction
