Where could I find some basic instruction on the use of the canvas
widget and its methods in Ruby Tk?

Thanks

Please see sample files under "<ruby-source-tree>/ext/tk/sample/".
And run "<ruby-source-tree>/ext/tk/sample/deme-en/widget",
select some of canvas widget demos,
click "Show Code" button, try to modify the code,
and click "Rerun Demo" button. :-)
Modification on the code window never change the original file.

After that, please see tk/canvas.rb and Tcl/Tk's canvas manual,
and compare Ruby/Tk's methods and Tcl/Tk's canvas subcommands.
Possibly you can get answers for many of your questions.
