Interface IIOParamController
An interface to set image parameters. An IIOParamController may be
a GUI component, a database reader, command-line parser or any
other means of getting parameter settings. For exampe, a dialog
box could implement IIOParamController to allow a user to adjust
JPEG compression levels.
The activate method should always behave modally; it should only
return when the action has been either cancelled or completed.
activate
public boolean activate(IIOParam param)
Activates the controller. A return value of false should mean
that no changes were made to param. A return value of true
should mean that the image is ready to be read or written.
param - the IIOParam to be modified
- true if the
IIOParam has been modified,
false otherwise
