There are many other possibilities when it comes to making use of imageData in paint programs, image processing applications, and so on, and it is still the same as in the preceding examples. In this chapter, we went over and understood the format of imageData, alphaData, and maskData and how to copy areas of imageData from one image to another. Reading individual pixels of an image and finding novel uses for the pixel values was covered here as well. We also saw how to use multitouch interactivity to bring those chunks of imageData to life in the form of a jigsaw puzzle.

Working with graphics can be great fun, hopefully, this will just be the start of what you will create. However, in the next chapter, we'll get back to making a utility application. Sigh…
