DESCRIPTION

       This package provides a command to take snapshots of arbitrary canvases.

API

       ::canvas::snap pathName
              Takes  a  snapshot of the canvas pathName. The result is the name of a new Tk photo
              image containing the snapshot.

              Note that this command has a side-effect. To avoid having  white  rectangles  where
              other  windows  may  overlap the canvas this command forces the toplevel window the
              canvas is in to the top of the stacking order.
