ABOUT QTGRAPHIMP

This sample code illustrates how to use QuickTime's graphics importer routines

to open and display image files. The graphics importer routines were introduced

in QuickTime version 2.5 as a new way to draw still images. The graphics import

routines (for example, GetGraphicsImporterForFile) use graphics import components

(of component type 'grip') to open and perform other operations on image files.

Essentially, you can use the graphics import routines to insulate your application

from the nitty gritty details of image file format and compression used in the

image.

In this sample code, we allow the user to open an image file; then we draw it into

a window on the screen. Your application, of course, will probably want to do more

interesting things with the image. We also allow the user to save an image using JPEG

compression.

Enjoy,
