Subject: canvas pixel commands?

Does the canvas allow for pixel level access? I am mostly interested in >getting the color at a certain pixel within the canvas.

The Img package includes img-window that can create a Tk photo image of the canvas window.

More recent Tk's (9.0?) have a canvas subcommand image that creates a Tk photo image of the canvas.

Once you have a Tk photo image, the get subcommand can read any pixel.
