Method Detail

showOperatorDialog

public void showOperatorDialog()

In this function implementations should handle displaying the OperatorImpl.operatorDialog via its show() method. Also any input parameters should if instantiated be loaded into the dialog prior to it being displayed. These should then be dislpayed after it is complete. NB this is modal dialog so once the show method is called execution will block. After the call the parameters can be got via OperatorDialog.getParameter(java.lang.String).

Specified by:

showOperatorDialog in interface Operator

Overrides:

showOperatorDialog in class OperatorImpl

execute

public java.awt.image.RenderedImage execute(java.awt.image.renderable.ParameterBlock inData)
                                     throws java.lang.Exception

Execute this operator with the input data passed as a parameter

Specified by:

execute in interface Operator

Overrides:

execute in class OperatorImpl

Parameters:

inData - - The input data to this operator

Throws:

java.lang.Exception
