org.apache.batik.ext.awt
Class MultipleGradientPaint

java.lang.Object
  org.apache.batik.ext.awt.MultipleGradientPaint

All Implemented Interfaces:: java.awt.Paint, java.awt.Transparency

Direct Known Subclasses:: LinearGradientPaint, RadialGradientPaint

public abstract class MultipleGradientPaint
extends java.lang.Object
implements java.awt.Paint

This is the superclass for Paints which use a multiple color gradient to fill in their raster. It provides storage for variables and enumerated values common to LinearGradientPaint and RadialGradientPaint.

Nested Class Summary

static class MultipleGradientPaint.ColorSpaceEnum
          Inner class to allow for typesafe enumerated ColorSpace values.

static class MultipleGradientPaint.CycleMethodEnum
          Inner class to allow for typesafe enumerated CycleMethod values.

Field Summary

protected java.awt.Color[] colors
          Gradient colors.

protected MultipleGradientPaint.ColorSpaceEnum colorSpace
          The colorSpace in which to perform the interpolation.

protected MultipleGradientPaint.CycleMethodEnum cycleMethod
          The method to use when painting out of the gradient bounds.

protected float[] fractions
          Gradient keyframe values in the range 0 to 1.

protected java.awt.geom.AffineTransform gradientTransform
          Transform to apply to gradient.

static MultipleGradientPaint.ColorSpaceEnum LINEAR_RGB
          Indicates that the color interpolation should occur in linearized RGB space.

static MultipleGradientPaint.CycleMethodEnum NO_CYCLE
          Indicates (if the gradient starts or ends inside the target region) to use the terminal colors to fill the remaining area.

static MultipleGradientPaint.CycleMethodEnum REFLECT
          Indicates (if the gradient starts or ends inside the target region), to cycle the gradient colors start-to-end, end-to-start to fill the remaining area.

static MultipleGradientPaint.CycleMethodEnum REPEAT
          Indicates (if the gradient starts or ends inside the target region), to cycle the gradient colors start-to-end, start-to-end to fill the remaining area.

static MultipleGradientPaint.ColorSpaceEnum SRGB
          Indicates that the color interpolation should occur in sRGB space.

protected int transparency
          Transparency.

Constructor Summary

MultipleGradientPaint(float[] fractions, java.awt.Color[] colors, MultipleGradientPaint.CycleMethodEnum cycleMethod, MultipleGradientPaint.ColorSpaceEnum colorSpace, java.awt.geom.AffineTransform gradientTransform)
          Superclass constructor, typical user should never have to call this.

Method Summary

java.awt.Color[] getColors()
          Returns a copy of the array of colors used by this gradient.

MultipleGradientPaint.ColorSpaceEnum getColorSpace()
          Returns the enumerated type which specifies color space for interpolation.

MultipleGradientPaint.CycleMethodEnum getCycleMethod()
          Returns the enumerated type which specifies cycling behavior.

float[] getFractions()
          Returns a copy of the array of floats used by this gradient to calculate color distribution.

java.awt.geom.AffineTransform getTransform()
          Returns a copy of the transform applied to the gradient.

int getTransparency()
          Returns the transparency mode for this LinearGradientPaint.
