ColorIterator.LuminanceStepper

public ColorIterator.LuminanceStepper(float stepping)
                               throws IllegalArgumentException

Creates an instance with the given stepping to go on the luminance line of the color space.

Parameters:

stepping - the stepping for each step in between 0.0 and 1.0.

Throws:

IllegalArgumentException - if stepping is <= 0.0 or >= 1.0.

Method Detail

doStep

public void doStep(ColorIterator tostep)

Performs a luminance step on the given ColorIterator's HSBColor.

The bounds are watched: if a step would cross 1.0f, it will be continued beginning from 0. if a step would cross the luminance value of the ColorIterator's start luminance, 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.
