Importing and Exporting Graphics
QuickTime offers many
components whose job is to import from
and export to different graphics formats. As you might expect, these
components are wrapped by classes called
GraphicsImporter
and GraphicsExporter.
The GraphicImportExport example application (shown
in Example 4-3) uses both of these classes to
illustrate the dynamic lookup of importers and exporters.
Note
Compile and run this example with ant run-ch04-graphicimport-export..
