Constructor Detail

IlvMakeValleyInteractor

public IlvMakeValleyInteractor(IlvInputStream stream)

The stream constructor.

Parameters:

stream - The Stream to read from.

IlvMakeValleyInteractor

public IlvMakeValleyInteractor()

Creates an interactor.

Method Detail

getActivityDescription

protected String getActivityDescription()

Returns the activity description displayed in the thread monitor.

Overrides:

getActivityDescription in class IlvMakeGradientInteractor

Returns:

The activity description displayed in the thread monitor.

See Also:

IlvMakeGradientInteractor.getActivityDescription()

buildImage

public short[] buildImage(IlvRasterProperties p,
                          IlvThreadMonitoringData monitorInfo,
                          IlvManager manager,
                          IlvGradientRasterStyle style)

Returns a table of pixel values computed for the parameter passed.

The following code example shows how to implement this method:

 IlvAltitudeProvider pr = IlvAltitudeProviderProperty.GetAltitudeProvider(manager);
 int ncols = properties.getColumnPixelCount();
 int nligs = properties.getLinePixelCount();
 short pixels[] = new short[ncols * nligs];
 monitorInfo.updateProgress(10);
 for (int y = 0; y < nligs; y++) {
   for (int x = 0; x < ncols; x++) {
      double xlon = p.getX() + x * p.getHorizontalPixelDensity();
      double ylat = p.getY() + y * p.getVerticalPixelDensity();
      double slope = pr.getAltitude(manager, xlon, ylat, 0);
      pixels[y * ncols + x] = (short) (slope);
   }
 }
 monitorInfo.updateProgress(100);
 return pixels;
 

Specified by:

buildImage in interface IlvImageComputation

Overrides:

buildImage in class IlvMakeGradientInteractor

Parameters:

p - The raster properties of the image to create.

monitorInfo - The thread monitoring reference.

manager - The manager to create the image for.

style - The style of the raster image.

Returns:

The table of pixels to be displayed in the raster image. This is compatible with the properties color model.

See Also:

IlvMakeGradientInteractor.getLayerName()

getDialogTitle

protected String getDialogTitle()

Returns the settings dialog title.

Overrides:

getDialogTitle in class IlvMakeGradientInteractor

Returns:

mustReload

public boolean mustReload(StyleEvent event)

Indicates if a specific style event necessitates rebuilding the raster data source.

Specified by:

mustReload in interface IlvMapLayerStyleControl

Overrides:

mustReload in class IlvMakeGradientInteractor

Parameters:

event - The event sent by the StyleListener instance installed on the layer style.

Returns:

When a rebuild is necessary, true is returned.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvMakeGradientInteractor

Parameters:

stream - the output stream
