Python, Imagemagick, and subprocess call
Question: Trying to use a subprocess call in a python script to run an Imagemagick
command. **I installed imagemagick in /usr/local/Cellar, so I tried two
options** since it looked like it wasn't finding the convert command.

By the way, the 'convert' command is an imagemagick one. :) Here is the part
of my code that directly relates to it.

    
    
    import sys, os, subprocess, string
    tempo = 8; #this is just for sample purposes, in the actual code this variable is imported from a csv file
    
    # test with just captioning one image and not whole loop
    subprocess.call('convert rgb10.png -pointsize 50 -draw "text 180,180 ' + str(tempo) + '" rgb10-n.png')
    

I've also tried
_"subprocess.call('/usr/local/Cellar/imagemagick/6.8.9-8/bin/c...."_ since I
thought it maybe wasn't finding the command.

Also, I **when I run this command in my terminal command line (not in a
script), it works** `(ex: convert rgb298.png -pointsize 50 -draw "text 180,180
'test' " rgb298-n.png)` so I know it must be an issue with my subprocess call.

This is the **error I receive** when I run it:

    
    
       subprocess.call('/usr/local/Cellar/imagemagick/6.8.9-8/bin/convert rgb10.png -pointsize 50 -draw "text 180,180 ' + str(tempo[9]) + '" rgb10-n.png')
      File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 470, in call
        return Popen(*popenargs, **kwargs).wait()
      File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 623, in __init__
        errread, errwrite)
      File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 1141, in _execute_child
        raise child_exception
    OSError: [Errno 2] No such file or directory
    

_NOTE: I also tried subprocess.call('python2.6 convert rgb10.png ..._


Answer: ... And I've gotten it to work, it was silly!

Added , shell=True

    
    
    subprocess.call('convert rgb10.png -pointsize 50 -draw "text 180,180 ' + str(tempo) + '" rgb10-n.png', shell=True)
    

and it works now for anyone else running into this issue.

**Except it's NOT actually drawing or taking into the account the variable
'tempo', aka not processing the + str(tempo) + bit**
