You can render any flowable anywhere by calling 'wrap' first with a big 
enough width and height (this is needed for paragraphs for obvious 
reasons, but it's a formality you just need to observe for rectangular 
shapes), then drawOn(canvas, x, y) with the desired location.  I can't 
remember right now if x,y is top or bottom left but I'm sure you'll 
figure it out in seconds ;-)

b = MyBarCode(options)
b.wrap(10*cm, 3*cm)   #any figures big enough will do
b.drawOn(canvas, x, y)   #where you want it drawn...
