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 java.awt.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 java.awt.geom.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 interfacejava.awt.Transparency
- Returns:
- an integer value representing the transparency mode for this Paint object
