Rixicons The big picture.

Rixicons is a tentative program both to extract icons and to test the NSWorkspace methods iconForFile:, iconForFiles:, and iconForFileType:.

The largest possible format is always used: on 10.4 this will be 128x128 and on 10.5 this will be a 'directory' with the largest image being 512x512. Images are automatically compressed and TIFF is used throughout.
