 java.awt.MultipleGradientPaint
All known Subclasses: java.awt.RadialGradientPaint, java.awt.LinearGradientPaint,
| MultipleGradientPaint | | abstract public class MultipleGradientPaint implements Paint(Code) | | 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 .

Parameters:
fractions - numbers ranging from 0.0 to 1.0 specifying thedistribution of colors along the gradient
Parameters:
colors - array of colors corresponding to each fractional value
Parameters:
cycleMethod - either NO_CYCLE , REFLECT ,or REPEAT
Parameters:
colorSpace - which color space to use for interpolation, either SRGB or LINEAR_RGB
Parameters:
gradientTransform - transform to apply to the gradient
throws:
NullPointerException - if fractions array is null,or colors array is null,or gradientTransform is null,or cycleMethod is null,or colorSpace is null
throws:
IllegalArgumentException - if fractions.length != colors.length ,or colors is less than 2 in size,or a fractions value is less than 0.0 or greater than 1.0,or the fractions are not provided in strictly increasing order |
| getColorSpace | | final public ColorSpaceType getColorSpace()(Code) | | Returns the enumerated type which specifies color space for
interpolation.
the enumerated type which specifies color space forinterpolation |
| getColors | | final public Color[] getColors()(Code) | | 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.
a copy of the array of colors used by this gradient |
| getCycleMethod | | final public CycleMethod getCycleMethod()(Code) | | Returns the enumerated type which specifies cycling behavior.
the enumerated type which specifies cycling behavior |
| getFractions | | final public float[] getFractions()(Code) | | 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.
