Method Detail

registerImageOperators

public static void registerImageOperators()
                                   throws Exception

This method initializes every IQM image processing operator of the standard operator bundle.

In order to register an image operator, one has to call register() on the operator's IOperatorDescriptor like

 IOperatorDescriptor myDescriptor = IqmOpThresholdDescriptor.register();
 

In order to use the operator with the JAI system using JAI.create(String, Object) from anywhere in the operators, one has to call registerWithJAI(), too, like

 IqmOpThresholdDescriptor.registerWithJAI();
 

A convenient method for displaying the registration process on the start screen is provided by calling updateWelcomeText(String), like

 updateWelcomeText(thresDesc.getName());
 

Throws:

Exception - if an operator's descriptor encounters any errors
