Class FractionBasedFillPainter

java.lang.Object
  org.jvnet.substance.api.painter.FractionBasedPainter
      org.jvnet.substance.api.painter.fill.FractionBasedFillPainter

All Implemented Interfaces:

SubstanceTrait, SubstanceGradientPainter

public class FractionBasedFillPainter
extends FractionBasedPainter
implements SubstanceGradientPainter

Fill painter with fraction-based stops and a color query associated with each stop. This class allows creating multi-gradient fills with exact control over which color is used at every gradient control point.

Constructor Detail

FractionBasedFillPainter

public FractionBasedFillPainter(java.lang.String displayName,
                                float[] fractions,
                                ColorSchemeSingleColorQuery[] colorQueries)

Creates a new fraction-based fill painter.

Parameters:

displayName - The display name of this painter.

fractions - The fractions of this painter. Must be strictly increasing, starting from 0.0 and ending at 1.0.

colorQueries - The color queries of this painter. Must have the same size as the fractions array, and all entries must be non- null.

                                   java.awt.Component comp,

Description copied from interface: SubstanceGradientPainter

Paints the background that matches the specified parameters.

Specified by:

paintContourBackground in interface SubstanceGradientPainter

Parameters:

g - Graphics context.

comp - Component to paint.

width - Width of a UI component.

height - Height of a UI component.

contour - Contour of a UI component.

isFocused - Indication whether component owns the focus.

colorScheme1 - The first color scheme.

colorScheme2 - The second color scheme.

cyclePos - Cycle position. Is used for rollover and pulsation effects. Must be in 0..1 range.

hasShine - Indication whether the returned image should have a 3D shine spot in its top half.

useCyclePosAsInterpolation - Indicates the algorithm to use for computing various colors. If true, the cyclePos is used to interpolate colors between different color components of both color schemes. If false, the cyclePos is used to interpolate colors between different color components of the first color scheme.
