Package: python3-pyocr
Version: 0.3.0-1
Severity: normal
Dear Maintainer,
experimenting a bit with OCR, i stumbled upon pyocr.
Unfortunately, I cannot seem to make it work (at least with the tesseract
backend), as it seems to require a different tesseract version (that uses
different cmdline arguments):

>>> import pyocr
>>> import pyocr.builders
>>> from PIL import Image
>>> captcha=Image.open("captcha.png")
>>> tools = pyocr.get_available_tools()
>>> tools
[<module 'pyocr.tesseract' from
'/usr/lib/python3/dist-packages/pyocr/tesseract.py'>]
>>> tool = tools[0]
>>> txt = tool.image_to_string(captcha, builder=pyocr.builders.TextBuilder())
Traceback (most recent call last):

The Cuneiform backend works nicely.
