Constructor Detail

TransRastThread

public TransRastThread(GISFrame gisFrame,
                       TransRastBox trb)

Transforms raster values using parameters given in trb.

Parameters:

gisFrame - GISFrame holding raster to transform.

trb - GUI box containing raster transformation parameters.

Method Detail

doProcessing

public void doProcessing()

Transform raster. The order of transformations is (i) substitution; (ii) translation; (iii) scaling; (iv) rounding; (v) flooding. The raster map containing the transformed values can be retrieved via getTransformedRaster() or by calling gisFrame.getRaster1().

Note that this method will be called automatically if this is run as a threaded process (e.g. myTransRastThread.start()). Alternatively it can be called directly as a non-threaded process.

Specified by:

doProcessing in class LSThread

GISFrame

getTransformedRaster

public RasterMap getTransformedRaster()

Retrieves the newly created transformed raster.

Returns:

New transformed raster, or null if process yet to take place.
