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.
