TypeError running # Example with PNG in usage guide about python-barcode HOT 9 CLOSED

Ok so I finally figured out what this is. ImageWriter tries to import Image, which used to come from PIL, (Python Image Library) which is no longer supported or included with Python. This issue can be remedied by installing Pillow, which is a working fork of PIL.

Side note: Pretty sure this makes Pillow a dependency for python-barcode.

Pillow is listed as an optional dependency, not PIL.
Some docs still have outdated PIL references, so I've updated these.

It runs when using writer=ImageWriter, but then an SVG image is created. Not a PNG.

I see it now. Maybe PIL should be specified or linked as pillow? PIL is no longer entirely accurate, since only a fork works.

pls ,update PIL to Pillow for python3, and add the Pillow dependency to be must when pip install python-barcode

@wellmonwu Please see previous comments. PIL has never been listed as a dependency; only pillow. Also, python2 has never supported, only python3.

Finally, pillow is only required if you're exporting image files (eg: not svg), so it will always be listed as an optional dependency, not a"must".

@WhyNotHugo Perhaps this could explicitly be stated in the error.
