  ========
  
  A command to mask secret information of images using OCR.
  
  Prerequisite
  ------------
  
  -  Python 3.3+
  -  `Tesseract <https://github.com/tesseract-ocr/tesseract>`__
  -  Languages for OCR (can be set by ``--lang``, default is ``eng+jpn``)
     must be available.
  
  Installation
  ------------
  
  ::
  
      $ pip3 install masecret
  
  You may need ``sudo``.
  
  masecret depends on `pyocr <https://github.com/jflesch/pyocr>`__ and
  `Pillow <https://pillow.readthedocs.io/>`__. If you fail to install
  Pillow, please see the installation instruction of Pillow.
  
  Usage
  -----
  
  Preparation
  ~~~~~~~~~~~
  
  Create a ``SECRETS.txt`` in a current directory. Content of the file is
  regular expression patterns which match secret information you want to
  mask. You can includes multiple patterns using multi lines.
  
  Example content of ``SECRETS.txt`` to mask AWS account number:
  
  ::
  
      [-\d]{12,}
  
  Mask Secret
  ~~~~~~~~~~~
  
  Mask a single file:
  
  ::
  
      $ masecret original.png masked.png
  
  Mask multiple files (output directory must exist):
  
  ::
  
      $ masecret original1.png original2.png ... masked_images/
