NAME


canvas::snap - Canvas snapshot to Tk photo image






SYNOPSIS


package require Tcl 8.5


package require Tk 8.5


package require canvas::snap ?1.0.1?


package require img::window 


::canvas::snap pathName










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.
