Constructor Detail

ColorIterator.AlphaStepper

public ColorIterator.AlphaStepper()

Creates an instance with 100 alpha steps.

ColorIterator.AlphaStepper

public ColorIterator.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 Detail

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.
