Constructor Detail

ColorScalePane

public ColorScalePane(ColorScale cs)

Create a ColorScalePane using the provided ColorScale. This class will assume, that the ColorScale is continuous and will thus generate a Linear gradient from the ColorScale.

Parameters:

cs - The ColorScale to use for this component.

Method Detail

paintScale

protected void paintScale(Graphics g,
                          int w,
                          int h)

This helper function paints a LinearGradientPaint on a graphics object. Unfortunately directly printing it to a panel will mess up the size, so we print it to a image instead in paintComponent

Parameters:

g - The graphics object to paint to

w - The width of the gradient

h - the height of the gradient

paintComponent

protected void paintComponent(Graphics g)

Overrides:

paintComponent in class JComponent

getImage

public BufferedImage getImage(int width,
                              int height)

Get an image that represents this ColorScalePane, with the given width and height

Parameters:

width - the Width of the image

height - The height of the image.

Returns:

an Image of this colorscalepane
