Calling Command Line ImageMagick from Python 3.6 Subprocess Module

[fmw42]

I have just now played around with subprocess module in Python using ImageMagick 6.9.9.20 Q16 Mac OSX Sierra. Both of the following work for me. See http://www.bogotobogo.com/python/python ... module.php

These are the two scripts (on my desktop)

subprocess_convert1.py

Code: Select all

#!/opt/local/bin/python3.6

import subprocess

cmd = ['/usr/local/bin/convert','-size','30x40','xc:white','-fill','white','-fill','black','-font','Arial','-pointsize','40','-gravity','South','-draw',"text 0,0 'P'",'/Users/fred/desktop/draw_text1.gif']

subprocess.call(cmd, shell=False)

subprocess_convert2.py

Code: Select all

#!/opt/local/bin/python3.6

import subprocess

cmd = '/usr/local/bin/convert -size 30x40 xc:white -fill white -fill black -font Arial -pointsize 40 -gravity South -draw "text 0,0 \'P\'" /Users/fred/desktop/draw_text2.gif'

subprocess.call(cmd, shell=True)

They are called in a bash shell terminal with:

Code: Select all

python3.6 subprocess_convert1.py

or

python3.6 subprocess_convert2.py

They both result in
