public class SimpleAppletDecoder
extends Applet
implements Runnable

This applet implements a simple mean to embed the JJ2000 decoder in an HTML page. The applet accepts all the parameters of the JJ2000 decoder, except output files. The image is downloaded, decoded and shown in the applet area. Scrollbars appear if the image is larger than the applet area.

An example use could be:

<applet code="jj2000.j2k.decoder.SimpleAppletDecoder.class"
 archive="jj2000-aplt.jar"
 width="512" height="512">
   <param name="i" value="tools.jp2">
   <param name="res" value"3">
</applet>

Constructor Detail

SimpleAppletDecoder

public SimpleAppletDecoder()
Method Detail

init

public void init()
Initializes the applet. It reads the parameters and creates the decoder thread.

Overrides:
init in class Applet

start

public void start()
Starts the decoding thread.

Overrides:
start in class Applet

stop

public void stop()
Does nothing, since the decoder thread can not be stopped.

Overrides:
stop in class Applet

destroy

public void destroy()
Waits for the decoder thread to end and sets it to null.

Overrides:
destroy in class Applet

run

public void run()
The run method for the decoding thread. Instantiates the decoder, runs it and updates the status message.

Specified by:
run in interface Runnable

getAppletInfo

public String getAppletInfo()
Returns the applet information (version, copyright, etc.)

Overrides:
getAppletInfo in class Applet
Returns:
A multi-line string containing the applet name, version, copyright and bug reporting address.

getParameterInfo

public String[][] getParameterInfo()
Returns the applet parameter information. See Applet class.

Overrides:
getParameterInfo in class Applet
See Also:
Applet.getParameterInfo()
