   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.

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.
