NAME

       MagnifyTool - tool for magnifying a portion of the GraphicView displayed in a viewer

SYNOPSIS

       #include <Unidraw/Tools/magnify.h>

DESCRIPTION

       MagnifyTool  lets the user magnify a portion a viewer's contents.  The user sweeps out a rectangular area
       with the MagnifyTool, and the viewer will magnify the area to occupy the entire screen, if possible.

PUBLIC OPERATIONS

       MagnifyTool(ControlInfo* = nil)
              Instantiate a MagnifyTool.

       virtual Manipulator* CreateManipulator(
          Viewer*, Event&, Transformer*
       )

       virtual void InterpretManipulator(Manipulator*)
              CreateManipulator generates  a  DragManip  with  a  RubberRect  to  provide  visual  feedback  for
              specifying  the rectangular area to be magnified.  InterpretManipulator does not create a command;
              rather, it examines the DragManipulator's RubberRect and calls Magnify  on  the  viewer  with  the
              RubberRect's final coordinates.
