QuickTime 3 Reference
This chapter describes the base image decompressor, a component that performs tasks for image decompressor components, including the scheduling of asynchronous decompression operations.
You need the information in this chapter only if you are implementing an image decompressor component. For information on implementing an image decompressor component, see Chapter 4, "Image Compressor Components," in this reference guide and Chapter 4, "Image Compressor Components," in Inside Macintosh: QuickTime Components.
