All Implemented Interfaces:

public class IlvRasterUSRPReader
extends IlvRasterASRPReader

This class reads an image from a USRP file. It needs the .IMG, .GEN and .QUA files to be able to parse bitmap data. It can create a pixel on-demand image using the tile loader mechanism. It extends IlvRasterASRPReader and overrides its base methods, searching for USRP specific content.
