pytesseract.pytesseract.tesseract_cmd = '/usr/local/bin/tesseract'

# TESSERACT_CONFIG
# psm 11 Sparse text. Find as much text as possible in no particular order
# => just for testing (3 is default)
TESSERACT_CONFIG = \
    '--oem 3 \
    --psm 11 \
    --tessdata-dir "/home/johannes/Repos/tesseract/tessdata/tessdata_fast"'
IMAGE_PATH = '/media/sf_firmprofiles/many_years_firmprofiles/short/oneprof'
FILENAME = 'oneprof.jpg'

filepath = os.path.join(IMAGE_PATH, FILENAME)
image = Image.open(filepath)
# text = pytesseract.image_to_string(image)
print(pytesseract.__doc__)

text = pytesseract.image_to_string(
    image,
    lang='deu',
    config=TESSERACT_CONFIG
