_________________________________________________________________


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.


KEYWORDS
