QuickTime 4 Reference

Getting/Setting the Destination Rectangle

QuickTime 4 adds two new calls which let applications access a graphics importer's destination rectangle.

The following functions are new to QuickTime 4:

GraphicsImportSetDestRect
GraphicsImportGetDestRect

Figure 16-2 shows an example with the following four rectangles: natural bounds, source rectangle, bounds rectangle, and a destination rectangle. You can access the destination rectangle in QuickTime 4 with these new calls.

In Figure 16-2 , the matrix scales by 200% vertically and translates 200 pixels to the right.
