public class AveragerApplet
extends javax.swing.JApplet
implements javax.swing.event.ChangeListener, java.awt.event.ActionListener

Applet for averaging multiple pre-delineated images, or adding new images and auto-delineating them. Images are added by calling a method from the browser (e.g. in a separate frame). The URL of the new image is passed as a String, usually this will be after a successful upload. The method to add the image to the applet can be called as part of the response to the upload form, e.g. during the page loading. This prevent the need for reloading the entire applet each time.

Constructor Detail


public AveragerApplet()
Method Detail


public void init()
Initializes the applet AverageApplet, setting up the GUI components and loading the pre-delineated images as specified as applet parameters.

init in class java.applet.Applet


public void loadFormImage(java.lang.String url)
Method to load a new (undelineated) image into the applet. It is usually called by the browser after a successful image upload.

url - A String giving the URL of the image to load into the applet.


public Template autoDelineate(java.awt.Image subjectImage,
                              java.awt.Point[] points)
Method to autodelineate a new image, using 3 points specified by the user.

subjectImage - The image to delineate
points - The 3 points to initialise the semi-automatic delineation
Returns the estimated template for the image.


public void actionPerformed(java.awt.event.ActionEvent e)
This method is called when the "Save to Browser" button is clicked. It writes the image data back to the server as though through a form submission the browser responds either with an error message (signaled by "error") or the URL of the saved image and the target window (e.g. "_blank" for a new browser window/tab. If successful, the applet then uses the showDocument method to get the browser to display the saved image as a jpeg.

Specified by:
actionPerformed in interface java.awt.event.ActionListener
e - The event that triggered this method.


public void stateChanged(javax.swing.event.ChangeEvent ae)
This method is called when a different tab is selected. tab 0 is the averaging tab, so it tries to calculate the average when this is clicked tab 1 is the grid of image buttons tab 2 is the delineation tab

Specified by:
stateChanged in interface javax.swing.event.ChangeListener
ae - The event that caused this method to be called.
