Description

DelegateOnlyComponent pretends to be an Image Codec. But all it does is delegate to a real Image Codec (in this case a '2vuy' decompressor).

This is a useful component sample to start with if you are writing a component to overide the functionality of another component, or just interested in seeing basic component functionality.

The project builds three targets:

1) A Test Application containing the DelegateOnly component linked into it that can be run as is.

2) A Test Application that requires the DelegateOnly component bundle to be installed in /Library/QuickTime/.

3) The DelegateOnly component bundle itself. This should be placed in /Library/QuickTime/.

This project builds universal binaries.
