from reportlab.graphics.shapes import Drawing
from reportlab.graphics.barcode.qr import QrCodeWidget

qrw =  QrCodeWidget('hello cruel world!')

b = qrw.getBounds()

w=b[2]-b[0]
h=b[3]-b[1]
d = Drawing(360,360,transform=[360./w,0,0,360./h,0,0])

d.add(qrw)
d.save(formats=['pdf','gif'],outDir='.',fnRoot='QR')
