These are all primitive data types, bits sitting in the computer's memory ready for our use. You probably specify them often-a float variable "speed", an int "x", etc. Hopefully, you are comfortable with the idea of data types. This tutorial is dedicated to breaking out of simple shape drawing in Processing and using images (and their pixels) as the building blocks of Processing graphics. With a little creative thinking and some lower level manipulation of pixels with code, however, we can display that information in a myriad of ways. Most of the time, we view these pixels as miniature rectangles sandwiched together on a computer screen.
If you see any errors or have comments, please let us know.Ī digital image is nothing more than data-numbers indicating variations of red, green, and blue at a particular location on a grid of pixels. This tutorial is from the book Learning Processing by Daniel Shiffman, published by Morgan Kaufmann, © 2008 Elsevier Inc.
