Classes	Description
SimplePixelReader	A simple pixel resampler class.

IPixelReader is a generic interface that is supported by any pixel reader, which provides pixel reading for RasterXformer.

The concrete pixel reader used in ArcGIS is SimplePixelReader. User can create a custom pixel reader by implementing this interface.
