14.3. Concepts Summary
In this chapter we explained how movies are stored and why they take up so much space. We created frame-based animations with simple geometric shapes, text, and images. We did special effects on movie frames, such as fading out and chromakey.
We created new versions of methods that take more parameters to make the methods more reusable. We also reused methods that we had created to work on Picture objects. When we program we try to create reusable parts. These reusable parts can be methods and/or classes.
