Description |
Datatype for storing images. Processing can display of .gif, .jpg, .tga, and .png images. Images may be displayed in 2D and 3D space. Before an image is used, it must be loaded with the loadImage() function. The PImage object contains fields for the width and height of the image, as well as an array called pixels[] which contains the values for every pixel in the image. A group of methods, described below, allow easy access to the image's pixels and alpha channel and simplify the process of compositing. |
