Processing.js includes full support for pixel and color manipulation of images on the canvas element. Images can be resized, tinted, blended, copied, resized, or have filters and masks applied to them. Images can also be manipulated at the pixel level allowing for any level of image manipulation required. Images can also be created and filled from pieces of other images, the current canvas content, or have their pixels filled dynamically. This functionality allows for images to be created from external data that is passed into the processing sketch and visualized through code.
