Constructor Detail

PuColorPicker

public PuColorPicker(java.awt.Color initColor)

Create a new color inspector with color wheel for picking colors. Note, PsConfig must be initialized prior to this call since PsImage needs the codeBase.

Version:

08.10.00, 1.30 revised (kp) Use static method PsImage#getImage instead of creating an instance of PsImage.
09.05.00, 1.25 revised (kp) Use of CodeBase removed when constructing PsImage.

Method Detail

init

public void init()

Description copied from class: PsPanel

Provides layout and adds internal components.

Overrides:

init in class PsPanel

Parameters:

imgWidth - width of color wheel image in pixel

imgHeight - height of color wheel image in pixel

brightness - brightness of image in [0,255]

pix - array stores color as integer, maybe null.
