Datatype for storing images. Processing can display <b>.gif</b>, <b>.jpg</b>, <b>.tga</b>, and <b>.png</b> images. Images may be displayed in 2D and 3D space. Before an image is used, it must be loaded with the <b>loadImage()</b> function. The <b>PImage</b> class contains fields for the <b>width</b> and <b>height</b> of the image, as well as an array called <b>pixels</b> that contains the values for every pixel in the image. The methods described below allow easy access to the image's pixels and alpha channel and simplify the process of compositing.<br/> <br/> Before using the <b>pixels</b> array, be sure to use the <b>loadPixels()</b> method on the image to make sure that the pixel data is properly loaded.<br/> <br/> To create a new image, use the <b>createImage()</b> function. Do not instantiate the object directly with the syntax <b>PImage()</b>.
