it's a mis-spelling in one way or another.
renderPM has a drawToFile function with signature


drawToFile(d,fn,fmt='GIF', dpi=72, bg=0xffffff, configPIL=None, 
showBoundary=rl_config._unset_)

and a save method which is actually the same.

The PMCanvas object from renderPM has a saveToFile method with arguments 
filename,format and drawings themselves have a save method which allows you to 
convert a drawing without using a specific renderer.


So you can do

renderPM.drawToFile(d, 'example1.png', 'PNG')
renderPM.save(d, 'example1.png', 'PNG')

or

d.save(formats=['PNG'],outDir='.',fnRoot='example1')

the latter is more useful if saving more than one format eg PDF & PNG. Also 
there's a useful py format which saves the low level drawing operations needed 
to create your drawing.
