Java Source Code / Java Documentation » 6.0 JDK Core » AWT » java.awt   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    java.awt.MultipleGradientPaintContext       java.awt.LinearGradientPaintContext LinearGradientPaintContext final class LinearGradientPaintContext extends MultipleGradientPaintContext (Code) Provides the actual implementation for the LinearGradientPaint. This is where the pixel processing is done. See Also:   java.awt.LinearGradientPaint See Also:   java.awt.PaintContext See Also:   java.awt.Paint author:    Nicholas Talian, Vincent Hardy, Jim Graham, Jerry Evans Constructor Summary   LinearGradientPaintContext(LinearGradientPaint paint, ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform t, RenderingHints hints, Point2D start, Point2D end, float[] fractions, Color[] colors, CycleMethod cycleMethod, ColorSpaceType colorSpace)      Constructor for LinearGradientPaintContext. Parameters:   paint - the LinearGradientPaint from which this contextis created Parameters:   cm - ColorModel that receivesthe Paint data. Method Summary protected  void fillRaster(int[] pixels, int off, int adjust, int x, int y, int w, int h)      Return a Raster containing the colors generated for the graphics operation. Constructor Detail LinearGradientPaintContext LinearGradientPaintContext(LinearGradientPaint paint, ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform t, RenderingHints hints, Point2D start, Point2D end, float[] fractions, Color[] colors, CycleMethod cycleMethod, ColorSpaceType colorSpace)(Code) Constructor for LinearGradientPaintContext. Parameters:   paint - the LinearGradientPaint from which this contextis created Parameters:   cm - ColorModel that receivesthe Paint data. This is used only as a hint. Parameters:   deviceBounds - the device space bounding box of the graphics primitive being rendered Parameters:   userBounds - the user space bounding box of the graphics primitive being rendered Parameters:   t - the AffineTransform from userspace into device space (gradientTransform should be concatenated with this) Parameters:   hints - the hints that the context object uses to choosebetween rendering alternatives Parameters:   dStart - gradient start point, in user space Parameters:   dEnd - gradient end point, in user space Parameters:   fractions - the fractions specifying the gradient distribution Parameters:   colors - the gradient colors Parameters:   cycleMethod - either NO_CYCLE, REFLECT, or REPEAT Parameters:   colorSpace - which colorspace to use for interpolation, either SRGB or LINEAR_RGB Method Detail fillRaster protected void fillRaster(int[] pixels, int off, int adjust, int x, int y, int w, int h)(Code) Return a Raster containing the colors generated for the graphics operation. This is where the area is filled with colors distributed linearly. x,y,w,h the area in device space for which colors aregenerated.
