The NotifyAllocator method informs the CDrawImage object whether the allocator for the connection is a CImageAllocator object.
void NotifyAllocator( BOOL bUsingImageAllocator );
Boolean value that indicates what kind of allocator is being used.
No return value.
The owning filter should call this method after the pins agree to an allocator. If the filter knows the allocator is a CImageAllocator object, it should call this method with the value TRUE. (Typically, the filter will know this only if it owns the allocator in question.) Otherwise, it should call this method with the value FALSE.
