The DirectShow Transform Filter Wizard
To ease the job of creating Microsoft DirectShow Transform filters, Microsoft s Ross Cutler has written the Transform Filter Wizard for Microsoft Visual Studio .NET. With a few clicks, this wizard will create most of the code you need to support either a transform filter or an in-place transform filter, producing a Visual Studio .NET project as output. The wizard creates the class definitions and method implementations for a filter that does nothing, so you ll need to implement some methods yourself if you want it to do something useful.
