canvas::snap(3tk) Variations on a canvas canvas::snap(3tk) 







canvas::snap - Canvas snapshot to Tk photo image








package require Tcl 8.5


package require Tk 8.5


package require canvas::snap ?1.0.1?


package require img::window 


::canvas::snap pathName












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









  
::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.

    enhancements you may have for either package and/or documentation.
