Class IlvMultipleGradientPaint

java.lang.Object
  ilog.views.java2d.IlvMultipleGradientPaint

All Implemented Interfaces:

IlvPersistentObject, Paint, Transparency

Direct Known Subclasses:

IlvLinearGradientPaint, IlvRadialGradientPaint

public abstract class IlvMultipleGradientPaint
extends Object
implements Paint, IlvPersistentObject

This is the superclass for Paint implementations that use a multiple-color gradient to fill in their raster.

Since:

JViews 5.0

Paint, IlvLinearGradientPaint, IlvRadialGradientPaint

Field Summary

static short	LINEAR_RGB Indicates that the color interpolation should occur in linearized RGB space.
static short	SPREAD_PAD Indicates that if the gradient starts or ends inside the target region, the remainder region should be filled with the terminal color of the gradient.
static short	SPREAD_REFLECT Indicates that if the gradient starts or ends inside the target region, the gradient should be reflected continuously until the remainder region is filled.
static short	SPREAD_REPEAT Indicates that if the gradient starts or ends inside the target region, the gradient should be repeated continuously until the remainder region is filled.
static short	SRGB Indicates that the color interpolation should occur in sRGB space.
