Create your own plugin

    Basic usage:

  1. Create your plugin by extending the AladinPlugin java class.
    (Aladin.jar file should be present in your CLASSPATH for the java compilation, ex: "javac -classpath Aladin.jar YourPlug.java")
  2. Use AladinData and Obj java classes for directly accessing and manipulating the Aladin data (image pixels, catalog objects...)
    Advanced usage:

  1. For controlling Aladin, you can use its VOApp interface (see FAQ VOApp doc)
  2. To be an Aladin listener, implement VOObserver interface (see FAQ VOObserver doc)
