Constructor Detail

VisionApplet2

public VisionApplet2()

Method Detail

init

public void init()

Called automatically when the applet is started. Initialises the interface components ready for drawing on screen.

Overrides:: init in class java.applet.Applet

set_images

public void set_images()

Sets up the default images

set_interface

public void set_interface()

set_interface sets up the 'standard' interface that is the same regardless of which operator is being run

add_extra

public void add_extra()

add_extra is used to add extra components to the window of the operator. This is done by adding extra components into the blank mid panel. This panel is then added to the generic panels to make up the interface. The default is for this panel to be blank.

set_src1_image2

public void set_src1_image2(int[] input_img,
                            int w,
                            int h,
                            java.lang.String name)

set_src1_image2 is used to add a newly loaded image to the interface It is called by set_src1_image once the operator thread has been recreated.

Parameters:: input_img - The new imput image array; w - The image width; h - The image height; name - The image name

set_src1_image

public void set_src1_image(int[] input_img,
                           int w,
                           int h,
                           java.lang.String name)

set_src1_image tells the applet of the image to be loaded and displayed on the screen. It also is required to recreate the operator which was running at the time. The method should be implemented by the subclass as this default doesn't do this.

Parameters:: input_img - The new input image array; w - The image width; h - The image height; name - The name of the image

set_src2_image2

public void set_src2_image2(int[] input_img,
                            int w,
                            int h,
                            java.lang.String name)

set_src2_image2 is used to add a newly loaded image to the interface It is called by set_src1_image once the operator thread has been recreated.

Parameters:: input_img - The new input image array; w - The image width; h - The image height; name - The image name

set_src2_image

public void set_src2_image(int[] input_img,
                           int w,
                           int h,
                           java.lang.String name)

set_src2_image tells the applet of the image to be loaded and displayed on the screen. It also is required to recreate the operator which was running at the time. The method should be implemented by the subclass as this default doesn't do this.

Parameters:: input_img - The new image array; w - The image width; h - The image height; name - The image name

apply_send_image

public void apply_send_image(int button)

apply_send_image grabs the image from the URL and turns it into an array of pixels which the operators can manipulate

getAppletInfo

public java.lang.String getAppletInfo()

Used by the browser to find out what the applet is for

Returns:: the function of the applet
Overrides:: getAppletInfo in class java.applet.Applet
