DESCRIPTION

       This package provides a widget to enable the user of a map display to control the zoom level.

API

       ::canvas::zoom pathName ?options?
	      Creates the zoom control widget pathName and configures it. The methods and options supported by the new widget are described in the
	      following sections.

	      The result of the command is pathName.

   OPTIONS
       -orient
	      The value for this option is either vertical, or horizontal, specifying the orientation of the major axis of the widget. The default
	      is vertical.

       -levels
	      The value for this option is a non-negative integer. It specifies the number of zoom levels to support.

       -variable
	      The  value  for  this  option is the name of a global or namespaced variable which is connected with the widget. changes to the zoom
	      level made the widget are propagated to this variable, and in turn changes to the variable are imported into the widget.

       -command
	      This option specifies a command prefix. This callback will be invoked whenever the zoom level is changed.  It  is  called  with  two
	      additional arguments, the zoom control widget, and the new zoom level, in this order.

   METHODS
       The widget supports no methods beyond the standard (configure, cget, etc.).
