Constructor Detail

ColorFilter

public ColorFilter(com.tensegrity.gui.swing.icon.ColorScale scale)

Creates a new ColorFilter based on the given ColorScale.

Parameters:

scale - the ColorScale instance to be used while processing pixels.

Method Detail

createColorFilteredImage

public static java.awt.Image createColorFilteredImage(java.awt.Image i,
                                                      com.tensegrity.gui.swing.icon.ColorScale scale)

Creates a new filtered image from the given parameter Image by using the given scale instance.

Parameters:

i - The image instance to filter.

scale - the ColorScale instance to use.

Returns:

a new filtered image.

filterRGB

public int filterRGB(int x,
                     int y,
                     int rgb)

This method filters the given pixel. The x,y are ignored. Each pixels hue value will be set to the stored value from the internal ColorScale instance. If the modification of the hue value had an impact on the rgb value, the luminance is additionally reduced about 15%. Thus black stays black, white white and gray gray.
