Constructor Detail


public ProjectionThread(GISFrame gisFrame,
                        SpatialObject spObject,
                        int newProjType)
Projects the given spatial object using the given transformer.

gisFrame - Frame holding spatial objects and in which to report results.
spObject - Spatial object to transform.
newProjType - Type of projection to perform.
Method Detail


public void doProcessing()
Reprojects the spatial object provided to the constructor. The newly created reprojected spatial object is added to the GISFrame provided to the constructor as either a primary raster or vector map. This can be retrieved directly via this class's method getReprojectedSpatialObject(), or by calling gisFrame.getRaster1(); or gisFrame.getVectorMap1();

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

Specified by:
doProcessing in class LSThread
See Also:


public SpatialObject getReprojectedSpatialObject()
Retrieves the reprojected spatial object.

Reprojected spatial object, or null if problem or process yet to take place.
