Constructor Detail
LinearGradientPaintContext
public LinearGradientPaintContext(ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform t, RenderingHints hints, Point2D dStart, Point2D dEnd, float[] fractions, Color[] colors, MultipleGradientPaint.CycleMethodEnum cycleMethod, MultipleGradientPaint.ColorSpaceEnum colorSpace) throws NoninvertibleTransformException(Code)
Constructor for LinearGradientPaintContext.
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
