In this case, please use canvas.configinfo(). 
On Ruby/Tk, to query the configuration options, 
use one of the following methods. 

 (1) widget[option]            #==> canvas['width']
 (2) widget.cget(option)       #==> canvas.cget('width')
 (3) widget.option             #==> canvas.width
 (4) widget.configinfo(option) #==> canvas.configinfo('width')
 (5) widget.configinfo         #==> canvas.configinfo

To modify the options, 

 (1) widget[option] = value          #==> canvas['width'] = 400
 (2) widget.option(value)            #==> canvas.width = 400
 (3) widget.configure(option, value) #==> canvas.configure('width', 400)
 (4) widget.configure(Hash)          #==> canvas.configure('width'=>400, 
                                                           'height'=>300)
