Summary

There are many other possibilities when it comes to making use of imageData; in paint programs, image processing applications, and so on. Dealing with the imageData is still the same as in the above examples, where we went over the following:

• Understanding the format of imageData, alphaData, and maskData

• Copying areas of imageData from one image to another

• Reading individual pixels of an image, and finding novel uses for that value

• We also saw how to use multi-touch 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!)
