  • Constructor Details

    • AlphaStepper

      public AlphaStepper()
      Creates an instance with 100 alpha steps.

    • AlphaStepper

      public AlphaStepper(int steps)
      Creates an instance with the given stepping to go on the alpha channel of the color space.

      Parameters:
      steps - the amount of steps to take on the saturation line.
  • Method Details

    • doStep

      public void doStep(ColorIterator tostep)
      Performs a alpha step on the given ColorIterator's HSBColor.

      The bounds are watched: if a step would cross 255, it will be continued beginning from 0. if a step would cross the alpha value of the ColorIterator's start alpha, the step will only go as far as this value. Else there would be problems with finding the end of the iteration.

      Parameters:
      tostep - the color iterator to perform the step on.
    • setSteps

      public void setSteps(int steps)
      Description copied from interface: ColorIterator.ISteppingModel
      Sets the amount of steps in the color space.

      Specified by:
      setSteps in interface ColorIterator.ISteppingModel
      Overrides:
      setSteps in class ColorIterator.ADefaultStepping
      Parameters:
      steps - the amount of steps in the color space.
