Introduction:

============

PyTesser is an Optical Character Recognition module for Python. It takes 

as input an image or image file and outputs a string.

PyTesser uses the Tesseract OCR engine (an Open Source project at Google), 

converting images to an accepted format and calling the Tesseract 

executable as an external script. A Windows executable is provided 

along with the Python scripts. The scripts should work in Linux as well.

Tesseract:

Dependencies:

=============

PIL is required to work with images in memory. PyTesser has been tested with Python 2.4 in Windows XP.

Installation:

==============

PyTesser has no installation functionality in this release.  Extract pytesser.zip

into directory with other scripts.  Necessary files are listed in File Dependencies below.  

Usage:

================================

>>> from pytesser import *

>>> im = Image.open('phototest.tif')

>>> text = image_to_string(im)

>>> print text

This is a lot of 12 point text to test the

ocr code and see if it works on all types

of file format.

... except errors.Tesser_General_Exception, value:

... 	print "fnord.tif is incompatible filetype.  Try graceful_errors=True"

... 	print value
