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.

KEYWORDS

canvas, image, photo, print screen, snapshot
