Constructor Detail

JSkyCatRemoteControl

public JSkyCatRemoteControl(int portNum,
                            JSkyCat jskycat)
                     throws java.io.IOException

Listen on the given port for remote commands to the given JSkyCat instance.

Throws:

java.io.IOException

Method Detail

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent e)

Called when the image processor settings are changed. Try to improve performance by not automatically scanning the image to find the best cut levels (tell it that the user set the cut levels and they should not be changed).

Specified by:

stateChanged in interface javax.swing.event.ChangeListener

drawImageGraphics

public void drawImageGraphics(BasicImageDisplay imageDisplay,
                              java.awt.Graphics2D g)

Called each time the image is repainted. This feature is (mis)used to get notification when the image has been displayed, since the graphics handlers are called after the image is painted. This is used to delay the reply for image display commands and avoid overwriting an image while the data is being read. With tiling, this can still happen, but only if the user is scrolling at the time.

Specified by:

drawImageGraphics in interface ImageGraphicsHandler

run

public void run()

Start accepting client connections.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread
