Description

This Tk widget creates three radio buttons which the user uses to indicate whether they wish to select pixels via an inclusion range (button `include'), an exclusion range (button `exclude') or select all (button `all') pixels. For the inclusion/exclusion ranges, two sliders with entry boxes to type into are provided for the user to set the range. The sliders are set to minimum and maximum and deactivated if the user selects the `all' radio button.

Currently, this widget is rather specialized. It will probably be made more generic at some point.
