public void displayLayers(javax.swing.JFrame frame,
                          org.geotools.map.MapContent map,

createGreyscaleStyle

public org.geotools.styling.Style createGreyscaleStyle(org.geotools.swing.JMapFrame frame)

Method to create a Style to display a selected band of the GeoTIFF image as a greyscale layer.

Returns:

a new Style instance to render the image in greyscale

createGreyscaleStyle

public org.geotools.styling.Style createGreyscaleStyle(int band)

Method to create a Style to display the specified band of the GeoTIFF image as a greyscale layer. This method is a helper for createGreyScale() and is also called directly by the displayLayers() method when the application first starts.

Parameters:

band - the image band to use for the greyscale display

Returns:

a new Style instance to render the image in greyscale

createRGBStyle

public org.geotools.styling.Style createRGBStyle()

Method to examine the names of the sample dimensions in the provided coverage looking for "red...", "green..." and "blue..." (case insensitive match). If these names are not found it uses bands 1, 2, and 3 for the red, green and blue channels. It then sets up a raster symbolizer and returns this wrapped in a Style.

Returns:

a new Style object containing a raster symbolizer set up for RGB image
