Class MultipleGradientPaint
java.lang.Object
java.awt.MultipleGradientPaint
- All Implemented Interfaces:
Paint, Transparency
- Direct Known Subclasses:
LinearGradientPaint, RadialGradientPaint
public abstract sealed class MultipleGradientPaint extends Object implements Paint permits LinearGradientPaint, RadialGradientPaint
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
| Modifier and Type | Class | Description |
|---|---|---|
static enum |
MultipleGradientPaint.ColorSpaceType |
The color space in which to perform the gradient interpolation. |
static enum |
MultipleGradientPaint.CycleMethod |
The method to use when painting outside the gradient bounds. |

BITMASK |
Represents image data that is guaranteed to be either completely opaque, with an alpha value of 1.0, or completely transparent, with an alpha value of 0.0. |
static final int |
OPAQUE |
Represents image data that is guaranteed to be completely opaque, meaning that all pixels have an alpha value of 1.0. |
static final int |
TRANSLUCENT |
Represents image data that contains or might contain arbitrary alpha values between and including 0.0 and 1.0. |

Method Details
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.
Note that if no transform is applied to the gradient when it is created, the identity transform is used.
- 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:
-
getTransparencyin interfaceTransparency - Returns:
-
OPAQUEif all colors used by thisPaintobject are opaque,TRANSLUCENTif at least one of the colors used by thisPaintobject is not opaque. - See Also:
