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.

Specified by:

mouseExited in interface java.awt.event.MouseListener

mouseEntered

public void mouseEntered(java.awt.event.MouseEvent event)

Do nothing.

Specified by:

mouseEntered in interface java.awt.event.MouseListener

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent event)

Do nothing.

Specified by:

mouseClicked in interface java.awt.event.MouseListener

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent event)

Invoce mousePressed.

Specified by:

mouseDragged in interface java.awt.event.MouseMotionListener

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent event)

Specified by:

mouseReleased in interface java.awt.event.MouseListener

Get current color selection.

getDefColor

public java.awt.Color getDefColor()

Get the default color.

setDefColor

public void setDefColor(java.awt.Color rgbColor)

Set the default color.

setColor

public void setColor(java.awt.Color rgbColor)

Set current color and values of rgb sliders. Value of brightness slider is not modified.

update

public boolean update(java.lang.Object event)

Update dialog if color slider or brightness slider has changed.

Overrides:

update in class PsPanel

Following copied from interface: jv.object.PsUpdateIf

Parameters:

event - carries a lot of information

getPreferredSize

public java.awt.Dimension getPreferredSize()

Get preferred size of this panel for inclusion in other containers.

Overrides:

getPreferredSize in class java.awt.Container

getWheel

public static java.awt.Image getWheel(int imgWidth,
                                      int imgHeight,
                                      int brightness,
                                      int[] pix)

Compute a color wheel in a square panel of size width == height.

Parameters:

imgWidth - width of color wheel image in pixel

imgHeight - height of color wheel image in pixel

brightness - brighness of image in [0,255]

pix - array stores color as integer, maybe null.
