LinearGradientPaint

public LinearGradientPaint(float startX,
                           float startY,
                           float endX,
                           float endY,
                           float[] fractions,
                           int[] colors,
                           MultipleGradientPaint.CycleMethod cycleMethod,

                           Transform gradientTransform)

Creates a LinearGradientPaint with the specified settings.

Parameters:

startX - The startX coordinate of the gradient in user space.

startY - The startY coordinate of the gradient in user space.

endX - The endX coordinate of the gradient in user space.

endY - THe endY coordinate of the gradient in user space.

fractions - Fractional positions of where gradient colors begin. Each value should be between 0 and 1.

colors - The colors to use in the gradient. There should be the same number of colors as there are fractions.

cycleMethod - The cycle method to use.

colorSpace - The color space to use.

gradientTransform - Transform to use for the gradient. Not used right now.
