change paper size to A0

[hitheng]

the default paper size is A4, wondering how to change it to A0, or even customized size.

I changed the width and height in the following code, but not working

def output(filename, markers, ids, nrows, ncols,
           blacklevel, whitelevel,
           scale, layout2,
           metric, minHamming, crcBits, idBits, width = 11.7, height = 16.5):
