Description: libimgsmlr
        ----------
        
        Implement the feature extraction function of the ``imgsmlr`` plugin, in
        languages such as: ``c(so file)``, ``Python``. Other languages should
        probably call dynamic libraries to adapt.
        
        When using the ``PostgreSQL`` plugin
        `imgsmlr <https://github.com/postgrespro/imgsmlr>`__, I found that the
        feature extraction functions provided by ``imgsmlr`` are all PostgreSQL
        functions. This poses a problem, as the files need to be uploaded to and
        stored in the database during testing. This is generally not possible in
        service development, where text is usually stored separately in the file
        system, and only paths and ``pattern``, ``signature`` are stored in the
        database. Therefore, it is necessary to implement the feature extraction
        functions used by the service development language.

        On Linux: ``yum install -y gd-devel``
        
        Installation
        ------------

            pip install libimgsmlr
        
        Examples
        --------
        
        .. code:: python
        
            from libimgsmlr import img2pattern, pattern2signature, shuffle_pattern
            if __name__ == "__main__":

                parser = argparse.ArgumentParser(description="libimgsmlr test")
                parser.add_argument('filename',help='image (jpeg/png/gif) file')
        
                args = parser.parse_args()
                print("filename: %s" % (args.filename))
                filename = args.filename
                content = open(filename, "rb").read()
                try:
                    pattern = img2pattern(content)
                    pattern2 = shuffle_pattern(pattern)

                    signature = pattern2signature(pattern)
                    print("signature: %s" % (signature))
                except ValueError as err:
                    print("ERROR: img2pattern(%s) failed! %s" % (filename, err))
