Chapter 5 - Bitmap Shapes
This chapter describes bitmap shapes and the functions you use to manipulate them. It also discusses functions described in other chapters and shows how you can apply them to bitmap shapes.Before you read this chapter, you should be familiar with the information in the chapter "Shape Objects" of Inside Macintosh: QuickDraw GX Objects, and you will probably want to be familiar with much of the information discussed in the chapters "Color and Color-Related Objects," "Transform Objects," and "View-Related Objects," also in that book.
This chapter introduces bitmap shapes, describes bitmap geometries, and then shows how to
- define bitmap geometries
- create bitmap shapes
- draw bitmap shapes
- manipulate the pixel image stored in a bitmap shape
- apply transfer modes and transformations to bitmap shapes
- draw other QuickDraw GX objects into a bitmap shape
- create bitmap shapes with disk-based pixel images
- replace a part of a bitmap shape's pixel image
