Take a look into the Tk commands help..canvas

I do like this but I can't remember which of these options do what.......




psfile.write(canvas2.postscript(fontmap='fontMap',
                   colormap='colorMap',
                   pageanchor='nw',
                   height='%2.1fc' %paper_height,
                   width='21.c',
                   pagex='0.c',
                   pagey='%2.1fc' %paper_height,
                   y='0.c', 
                   x='0.c'))
