Name PImage Examples PImage b; b = loadImage("laDefense.jpg"); image(b, 0, 0); Description Datatype for storing images. Processing can display .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. Before using the pixels[] array, be sure to use the loadPixels() method on the image to make sure that the pixel data is properly loaded. To create a new image, use the createImage() function (do not use new PImage()). Fields width Image width height Image height pixels[] Array containing the color of every pixel in the image Methods get() Reads the color of any pixel or grabs a rectangle of pixels set() Writes a color to any pixel or writes an image into another copy() Copies the entire image mask() Masks part of the image from displaying blend() Copies a pixel or rectangle of pixels using different blending modes filter() Converts the image to grayscale or black and white save() Saves the image to a TIFF, TARGA, PNG, or JPEG file resize() Changes the size of an image to a new width and height loadPixels() Loads the pixel data for the image into its pixels[] array updatePixels() Updates the image with the data in its pixels[] array Constructor PImage() PImage(width, height) PImage(width, height, format) PImage(img) Parameters width int: image width height int: image height format Either RGB, ARGB, ALPHA (grayscale alpha channel) img java.awt.Image: assumes a MediaTracker has been used to fully download the data and the img is valid Usage Web & Application Related loadImage()imageMode()createImage()

Processing was initiated by Ben Fry and Casey Reas. It is developed by a small team of volunteers.
