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.
