Creating a User-Mode Still Image Minidriver

All user-mode still image minidrivers must implement the interface methods defined by IStiUSD COM Interface. This implementation is relatively easy, using the following procedure.

To implement the methods defined by the IStiUSD COM interface:

1. Obtain a GUID for the interface, and include it in a header file and a setup information (INF) file.

2. Create an implementation file such as ( .cpp).

3. Create a customized class definition, using IStiUSD as an inherited class.

4. Implement all of the methods that have been defined for the IStiUSD COM Interface. If a method is not needed, it must return STIERR_UNSUPPORTED.
