An Image Unit and Its Parts

This tutorial provides detailed information on how to write the various parts of an image unit so that they work together as an image unit. It’s important that you have an idea not only of what the parts are, but how they fit together. This chapter provides such an overview. It describes the parts of an image unit, discusses what each one does, and provides guidelines for writing some of the components in an image unit.

Before you start this chapter, you should be familiar with the concepts described in Core Image Programming Guide, have already used some of the built-in image processing filters provided by Core Image, and understand the classes defined by the Core Image API (see Core Image Reference Collection).
