Inside Macintosh: QuickTime Components
This chapter discusses standard image-compression dialog components. Standard image-compression dialog components provide a consistent user interface for selecting parameters that govern the compression of an image or image sequence and the management of the compression operation. Applications that use these components are freed from many of the details of obtaining and validating image-compression parameters and interacting with the Image Compression Manager to compress an image or sequence.
If you want to use a standard image-compression dialog component in your application, you should read the first two sections of this chapter, and then use the reference section as appropriate. If you want to create your own standard image-compression dialog component, you should be familiar with all of the information in this chapter.
As components, standard image-compression dialog components rely on the facilities of the Component Manager. In order to use any component, your application must also use the Component Manager. If you are not familiar with this manager, see the chapter "Component Manager" in Inside Macintosh: More Macintosh Toolbox . In addition, you should be familiar with image compression in general and the Image Compression Manager in particular. See the chapter "Image Compression Manager" in Inside Macintosh: QuickTime for more information.
Throughout this chapter, the term standard dialog component refers to the standard image-compression dialog component. The term standard dialog box refers to one or both of the two dialog boxes presented by the standard image-compression dialog component. These dialog boxes are shown in Figure 1 and Figure 2 .
