canvas::snap - Canvas snapshot to Tk photo image
This package provides a command to take snapshots of arbitrary canvases.
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.
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category canvas of the Tklib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.
