I want to convert a tiff image file to text document. My code perfectly as I expected to convert tiff images with usual font but its not working for french script font . My tiff image file contains text. The font of text is in french script format.I here is my code

import Image

import subprocess

import util

import errors

tesseract_exe_name = 'tesseract' # Name of executable to be called at command line

scratch_image_name = "temp.bmp" # This file must be .bmp or other Tesseract-compatible 
format
scratch_text_name_root = "temp" # Leave out the .txt extension

cleanup_scratch_flag = True  # Temporary files cleaned up after OCR operation

def call_tesseract(input_filename, output_filename):

    """Calls external tesseract.exe on input file (restrictions on types),

    outputting output_filename+'txt'"""

    args = [tesseract_exe_name, input_filename, output_filename]

    proc = subprocess.Popen(args)


    retcode = proc.wait()

    if retcode!=0:

        errors.check_for_errors()

def image_to_string(im, cleanup = cleanup_scratch_flag):

    """Converts im to file, applies tesseract, and fetches resulting text.
    If cleanup=True, delete scratch files after operation."""

    try:

        util.image_to_scratch(im, scratch_image_name)

        call_tesseract(scratch_image_name, scratch_text_name_root)

        text = util.retrieve_text(scratch_text_name_root)

    finally:

        if cleanup:

            util.perform_cleanup(scratch_image_name, scratch_text_name_root)

    return text

def image_file_to_string(filename, cleanup = cleanup_scratch_flag, graceful_errors=True):

    try:

        try:

            call_tesseract(filename, scratch_text_name_root)

            text = util.retrieve_text(scratch_text_name_root)

        except errors.Tesser_General_Exception:

            if graceful_errors:



                im = Image.open(filename)

                text = image_to_string(im, cleanup)

            else:

                raise

    finally:

    text = image_to_string(im)

    print text

    try:

    except errors.Tesser_General_Exception, value:

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

        print value

    print text
