java.awt
Class MultipleGradientPaint

java.lang.Object
  java.awt.MultipleGradientPaint

All Implemented Interfaces:: Paint, Transparency

Direct Known Subclasses:: LinearGradientPaint, RadialGradientPaint

public abstract class MultipleGradientPaint
extends Object
implements Paint
extends Object
implements 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.

Since:: 1.6

Nested Class Summary

static class MultipleGradientPaint.ColorSpaceType
          The color space in which to perform the gradient interpolation.

static class MultipleGradientPaint.CycleMethod
          The method to use when painting outside the gradient bounds.

Field Summary

BITMASK, OPAQUE, TRANSLUCENT

Method Summary

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

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

MultipleGradientPaint.CycleMethod 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.

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

Method Detail

getFractions

public final float[] getFractions()

Returns a copy of the array of floats used by this gradient to calculate color distribution. The returned array always has 0 as its first value and 1 as its last value, with increasing values in between.

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

getColors

public final Color[] getColors()

Returns a copy of the array of colors used by this gradient. The first color maps to the first value in the fractions array, and the last color maps to the last value in the fractions array.

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

getCycleMethod

public final MultipleGradientPaint.CycleMethod getCycleMethod()

Returns the enumerated type which specifies cycling behavior.

Returns:: the enumerated type which specifies cycling behavior

getColorSpace

public final MultipleGradientPaint.ColorSpaceType getColorSpace()

Returns the enumerated type which specifies color space for interpolation.

Returns:: the enumerated type which specifies color space for interpolation

getTransform

public final AffineTransform getTransform()

Returns a copy of the transform applied to the gradient.

Returns:: a copy of the transform applied to the gradient

getTransparency

public final int getTransparency()

Returns the transparency mode for this Paint object.

Specified by:: getTransparency in interface Transparency

Returns:: an integer value representing the transparency mode for this Paint object
