Predefined iTool Visualization Classes

iTool Programming: Creating a Visualization

Predefined iTool Visualization Classes

The iTool system distributed with IDL includes a number of predefined visualization classes. The visualization type (the TYPE keyword value of the visualization with which it is initialized) and the accepted data type(s) are shown for the predefined visualization classes. You can include these visualization classes in an iTool directly by registering the class with your iTool (as described in Registering a Visualization Type). You can also create a new visualization class based on one of the predefined classes. Visualization classes are located in the lib/itools/components subdirectory of the IDL directory.
