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)

getPreferredSize

public java.awt.Dimension getPreferredSize()

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

Overrides:

getPreferredSize in class PsPanel

getWheelAsInt

public static int[] getWheelAsInt(int imgWidth,
                  int imgHeight,
                  int brightness,
                  int[] pix)

Compute a color wheel in a square panel of size width == height. Shows all RGB color triples which have the same maximum equal to the given parameter brightness.

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.

Returns:

updated pixel array

Compute a color wheel in a square panel of size width == height. Shows all RGB color triples which have the same maximum equal to the given parameter brightness.

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.

Returns:

newly created image
