"""
Wrapper for various OCR tools.
USAGE:
from PIL import Image
import sys
from pyocr import pyocr
tools = pyocr.get_available_tools()[:]
if len(tools) == 0:
print("No OCR tool found")
sys.exit(1)
print("Using '%s'" % (tools[0].get_name()))
tools[0].image_to_string(Image.open('test.png'), lang='fra',
builder=TextBuilder())
DETAILS:
Each module wrapping an OCR tool provides the following functions:
- get_name(): Return the name of the tool
- is_available(): Returns True if the tool is installed. False else.
- get_version(): Return a tuple containing the version of the tool (if
installed)
- get_available_builders(): Returns a list of builders that can be used with
this tool (see image_to_string())
- get_available_languages(): Returns a list of languages supported by this
tool. Languages are usually written using ISO 3 letters country codes
- image_to_string():
Takes 3 arguments:
- an image (see python Imaging "Image" module) (mandatory)
- lang=<language> (see get_available_languages()) (optional)
- builder=<builder> (see get_available_builders() or the classes in the
module 'pyocr.builders') (optional: default is
pyocr.builders.TextBuilder)
Returned value depends of the specified builder.
