Description: Read and write Netpbm files
        ===========================
        
        Netpbmfile is a Python library to read and write image files in the Netpbm
        format as specified at http://netpbm.sourceforge.net/doc/.
        
        The following Netpbm and Portable FloatMap formats are supported:
        
        * PBM (bi-level)
        * PGM (grayscale)
        * PPM (color)
        * PAM (arbitrary)
        * XV thumbnail (RGB332, read-only)
        * PF (float32 RGB, read-only)
        * Pf (float32 grayscale, read-only)
        
        No gamma correction is performed. Only one image per file is supported.

        Examples
        --------
        Save a numpy array to a Netpbm file in grayscale format:
        
        >>> data = numpy.array([[0, 1], [65534, 65535]], dtype='uint16')
        >>> imwrite('_tmp.pgm', data)
        
        Read the image data from a Netpbm file as numpy array:
        
        >>> image = imread('_tmp.pgm')
        >>> assert numpy.all(image == data)
        
        Access meta and image data in a Netpbm file:
        
        >>> with NetpbmFile('_tmp.pgm') as pgm:
        ...     pgm.axes
        ...     pgm.shape
        ...     pgm.dtype
        ...     pgm.maxval
        ...     pgm.magicnum
        ...     image = pgm.asarray()
        'YX'
        (2, 2)
        dtype('>u2')
        65535
        b'P5'
