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.
