IlvMultipleGradientPaint

public IlvMultipleGradientPaint(IlvMultipleGradientPaint source)

Creates a multiple gradient paint by copying an existing one.

Parameters:

source - The multiple gradient paint to be copied.

Since:

JViews 8.5

Method Detail

initTransparency

protected final void initTransparency()

Checks whether the gradient uses a transparent color. Internal method.

getColors

public final Color[] getColors()

Returns a copy of the array of colors used by this gradient.

Returns:

A copy of the array of colors used by this gradient.

getStops

public final float[] getStops()

Returns a copy of the array of floats used by this gradient to calculate color distribution.

Returns:

A copy of the array of floats used by this gradient to calculate color distribution.

getTransparency

public final int getTransparency()

Returns the transparency mode for this gradient.

Specified by:

getTransparency in interface Transparency

isAdapting

public final boolean isAdapting()

Returns true if the gradient is adapting itself on the shape it is drawn.

Specified by:

isAdapting in interface IlvAdaptablePaint

getSpreadMethod
