Constructor Details

GradientPaintContext

public GradientPaintContext(float x1,
                            float y1,
                            Color c1,
                            float x2,
                            float y2,
                            Color c2,
                            boolean cyclic)
Creates a new instance.
Parameters:
x1 - the x-coordinate for the anchor point for color 1.
y1 - the y-coordinate for the anchor point for color 1.
c1 - color 1.
x2 - the x-coordinate for the anchor point for color 2.
y2 - the y-coordinate for the anchor point for color 2.
c2 - color 2.
cyclic - a flag that determines whether the gradient is cyclic or acyclic.

Method Details

dispose

public void dispose()
Release the resources allocated for the paint (none in this implementation).
Specified by:
dispose in interface PaintContext

getColorModel

public ColorModel getColorModel()
Return the color model of this context. It may be different from the hint specified during createContext, as not all contexts can generate color patterns in an arbitrary model.
Specified by:
getColorModel in interface PaintContext
Returns:
the context color model

getRaster

public Raster getRaster(int x,
                        int y,
                        int w,
                        int h)
Return a raster containing the colors for the graphics operation.
Specified by:
getRaster in interface PaintContext
Parameters:
x - the x-coordinate, in device space
y - the y-coordinate, in device space
w - the width, in device space
h - the height, in device space
Returns:
a raster for the given area and color
