If your Tcl/Tk supports it and your Ruby/Tk links such Tcl/Tk, 
probably you can use the following line. 
--------------------------------------------------
ph = TkPhotoImage.new('format'=>'window', 'data'=>canvas_widget_path)
--------------------------------------------------
I cannot test it, because my Tk doesn't support 'window' format.
