I only try to get a photo attached in a mail and I get an error...
When I first save the image in the camera roll and I use the same script to get it, no error
Help needed
Thanks

# coding: utf-8
import appex
img = appex.get_image(image_type='pil')

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

How do you open the Pythonista extension from Mail?

Long press on the photo, run Pythonista script

Try running apex_dump.py in place of your script to see exactly what mail is passing to you. Did you try with jpeg instead of PIL?

@ccc @cvp it doesn't work at all. appex.get_input crashes as well.

Getting the image is not impossible though, since workflow can do it. (Create a new workflow with a single Quick Look action that accepts everything to test)

@ccc
Same error

@lukaskollmer

If I use ViewExif, it functions but Pythonista 3 crashes

Forcing Python 2 functions! bug of Python 3?

Workaround is to make sure that #! python2 is the first line of your script.

@ccc

That's what I did when I said it's ok in Python 2

As adviced by @ccc, this is ok even in Python 3

#img = appex.get_image()
f = appex.get_attachments()
img = Image.open(f[0])

A SystemError exception is nearly always a bug on my part. I'll look into it.

Thanks
Not vital as workaround of @ccc solves it.
