        Python-tesseract is an optical character recognition (OCR) tool for python.
        That is, it will recognize and "read" the text embedded in images.
        
        Python-tesseract is a wrapper for `Google's Tesseract-OCR Engine <https://github.com/tesseract-ocr/tesseract>`_.
        It is also useful as a stand-alone invocation script to tesseract, as it can read all image types
        supported by the Pillow and Leptonica imaging libraries, including jpeg, png, gif, bmp, tiff,
        and others. Additionally, if used as a script, Python-tesseract will print the recognized
        text instead of writing it to a file.
        
        USAGE
        -----
        
        **Quickstart**
        
        *Note*: Test images are located in the ``tests/data`` folder of the Git repo.
        
        Library usage:
        
        .. code-block:: python
        
            try:
                from PIL import Image
            except ImportError:
                import Image
            import pytesseract
        
            # If you don't have tesseract executable in your PATH, include the following:
            pytesseract.pytesseract.tesseract_cmd = r'<full_path_to_your_tesseract_executable>'
            # Example tesseract_cmd = r'C:\Program Files (x86)\Tesseract-OCR\tesseract'
        
            # Simple image to string
            print(pytesseract.image_to_string(Image.open('test.png')))
        
            # French text image to string
            print(pytesseract.image_to_string(Image.open('test-european.jpg'), lang='fra'))
        
            # In order to bypass the image conversions of pytesseract, just use relative or absolute image path
            # NOTE: In this case you should provide tesseract supported images or tesseract will return error
            print(pytesseract.image_to_string('test.png'))
        
            # Batch processing with a single file containing the list of multiple image file paths
            print(pytesseract.image_to_string('images.txt'))
        
            # Timeout/terminate the tesseract job after a period of time
            try:
                print(pytesseract.image_to_string('test.jpg', timeout=2)) # Timeout after 2 seconds
                print(pytesseract.image_to_string('test.jpg', timeout=0.5)) # Timeout after half a second
            except RuntimeError as timeout_error:
                # Tesseract processing is terminated
                pass
        
            # Get bounding box estimates
            print(pytesseract.image_to_boxes(Image.open('test.png')))
        
            # Get verbose data including boxes, confidences, line and page numbers
            print(pytesseract.image_to_data(Image.open('test.png')))
        
            # Get information about orientation and script detection
            print(pytesseract.image_to_osd(Image.open('test.png')))
        
            # Get a searchable PDF
            pdf = pytesseract.image_to_pdf_or_hocr('test.png', extension='pdf')
            with open('test.pdf', 'w+b') as f:
                f.write(pdf) # pdf type is bytes by default
        
            # Get HOCR output
            hocr = pytesseract.image_to_pdf_or_hocr('test.png', extension='hocr')
        
        Support for OpenCV image/NumPy array objects
        
        .. code-block:: python
        
            import cv2
        
            img_cv = cv2.imread(r'/<path_to_image>/digits.png')
        
            # By default OpenCV stores images in BGR format and since pytesseract assumes RGB format,
            # we need to convert from BGR to RGB format/mode:
            img_rgb = cv2.cvtColor(img_cv, cv2.COLOR_BGR2RGB)
            print(pytesseract.image_to_string(img_rgb))
            # OR
            img_rgb = Image.frombytes('RGB', img_cv.shape[:2], img_cv, 'raw', 'BGR', 0, 0)
            print(pytesseract.image_to_string(img_rgb))
        
        
        If you need custom configuration like `oem`/`psm`, use the **config** keyword.
        
        .. code-block:: python
        
            # Example of adding any additional options.
            custom_oem_psm_config = r'--oem 3 --psm 6'
            pytesseract.image_to_string(image, config=custom_oem_psm_config)
        
        Add the following config, if you have tessdata error like: "Error opening data file..."
        
        .. code-block:: python
        
            # Example config: r'--tessdata-dir "C:\Program Files (x86)\Tesseract-OCR\tessdata"'
            # It's important to add double quotes around the dir path.
            tessdata_dir_config = r'--tessdata-dir "<replace_with_your_tessdata_dir_path>"'
            pytesseract.image_to_string(image, lang='chi_sim', config=tessdata_dir_config)
        
        **Functions**

        INSTALLATION
        ------------
        
        Prerequisites:
        
        - Python-tesseract requires Python 2.7 or Python 3.5+
        - You will need the Python Imaging Library (PIL) (or the `Pillow <https://pypi.org/project/Pillow/>`_ fork).
          Under Debian/Ubuntu, this is the package **python-imaging** or **python3-imaging**.
        - Install `Google Tesseract OCR <https://github.com/tesseract-ocr/tesseract>`_
          (additional info how to install the engine on Linux, Mac OSX and Windows).
          You must be able to invoke the tesseract command as *tesseract*. If this
          isn't the case, for example because tesseract isn't in your PATH, you will
          have to change the "tesseract_cmd" variable ``pytesseract.pytesseract.tesseract_cmd``.
          Under Debian/Ubuntu you can use the package **tesseract-ocr**.
          For Mac OS users. please install homebrew package **tesseract**.
        
          *Note:* Make sure that you also have installed ``tessconfigs`` and ``configs`` from `tesseract-ocr/tessconfigs <https://github.com/tesseract-ocr/tessconfigs>`_ or via the OS package manager.
        
        | Installing via pip:
