canvas::snap - Canvas snapshot to Tk photo image

::canvas::snappathName
              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.

       This document, and the package it describes, will undoubtedly contain bugs and  other  problems.   Please
       report  such  in the category canvas of the TklibTrackers [http://core.tcl.tk/tklib/reportlist].  Please
       also report any ideas for enhancements you may have for either package and/or documentation.
