Composite resources

The ImageWorkstation object class has no composite class members.

Superclass resources

You can set all resources defined by the superclasses of the ImageWorkstation object class, including:

Workstation resources

Description

The ImageWorkstation object is derived from the Workstation class and thus inherits all of the color map management and control functions associated with the Workstation class.

Support functions

The ImageWorkstation object does not define any support functions; it inherits all the support functions available to its superclass.

Status

Experimental; currently only PNG format is supported. New in NCL 5.2.0.
