Method Detail

buildImage

short[] buildImage(IlvRasterProperties properties,
                   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;
 

Parameters:

properties - 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.
