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.
