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 com‐
mand forces the toplevel window the canvas is in to the top of
the stacking order.
