PythonMagick - why the parameters do not reflect the ones of 'convert'

I'm doing

img = PythonMagick.Image('image.jpg')
img.threshold(30)

Why this does not correspond to manually running

convert -threshold 30%

Same for 0.3. Similar problem with blur 0x1

EDIT: From documentation, threshold is related to quantum depth, which is usually 65536... So 30% is 19660.8 and the thread is solved?

Which documentation are you following? – Bibhas Debnath Oct 07 '13 at 12:47
I did not find any, so I was doing tests (and .__doc__) I found something here http://www.imagemagick.org/Magick++/Image.html but it does not describe how it works, definitely not like convert... I'd like to specify a percentage – Mercier Oct 07 '13 at 12:54
What is `img`? Show us the code. Here is some documentation http://www.imagemagick.org/download/python/README.txt – Bibhas Debnath Oct 07 '13 at 12:58
From the edit part, did it work? – Bibhas Debnath Oct 07 '13 at 13:06
Thanks for the documentation, yes it did work for threshold (I hope ;) ) but it is not full, e.g. no monochrome()... – Mercier Oct 07 '13 at 13:11
