Using the IlvRasterUSRPReader class to create images

To create the IlvRasterUSRPReader:

Provide the name of the .GEN file describing the USRP image:

IlvRasterUSRPReader imageReader = new IlvRasterUSRPReader();
imageReader.addMap(fileName);

The reader removes the extension, that is, the characters after the last period (.) at the end of the filename, and constructs the names of the .GEN, .IMG and .QAL files from that base name. Note that a field inside the .GEN file can possibly override this default mechanism.

To create a data source and link it with the manager properties:

Define and insert the data source in the data source tree:

IlvMapDataSource imageDataSource =
  IlvRasterDataSourceFactory.buildTiledImageDataSource(manager,imageReader,
    true,true,null);
IlvMapDataSourceModel dataSourceModel =
  IlvMapDataSourceProperty.GetMapDataSourceModel(manager);
dataSourceModel.insert(imageDataSource);

To start reading the data:

Start the data source:
```
dataSourceModel.start();
```

Starting the data source creates the necessary tiled layers, tile managers, and IlvRasterIcon instances to manage the pixel-on-demand feature and the progressive display of the geo-referenced image.
