This is a python interface to Adobe Font Metrics Files.  Although a
number of other python implementations exist, and may be more complete
than this, it was decided not to go with them because they were
either:

  1) copyrighted or used a non-BSD compatible license

  2) had too many dependencies and a free standing lib was needed

  3) Did more than needed and it was easier to write afresh rather than
     figure out how to get just what was needed.

It is pretty easy to use, and requires only built-in python libs:

    >>> from matplotlib import rcParams
    >>> import os.path
    >>> afm_fname = os.path.join(rcParams['datapath'],
    ...                         'fonts', 'afm', 'ptmr8a.afm')
    >>>
    >>> from matplotlib.afm import AFM
    >>> with open(afm_fname, 'rb') as fh:
    ...     afm = AFM(fh)
    >>> afm.string_width_height('What the heck?')
    (6220.0, 694)
    >>> afm.get_fontname()
    'Times-Roman'
    >>> afm.get_kern_dist('A', 'f')
    0
    >>> afm.get_kern_dist('A', 'y')
    -92.0
    >>> afm.get_bbox_char('!')
    [130, -9, 238, 676]

As in the Adobe Font Metrics File Format Specification, all dimensions
are given in units of 1/1000 of the scale factor (point size) of the font
being used.

    Reads the font metrics header (up to the char metrics) and returns
    a dictionary mapping *key* to *val*.  *val* will be converted to the
    appropriate python type as necessary; e.g.:

        * 'False'->False
        * '0'->0
        * '-168 -218 1000 898'-> [-168, -218, 1000, 898]

    Dictionary keys are

      StartFontMetrics, FontName, FullName, FamilyName, Weight,
      ItalicAngle, IsFixedPitch, FontBBox, UnderlinePosition,
      UnderlineThickness, Version, Notice, EncodingScheme, CapHeight,

    Represents the character metrics of a single character.

    Notes
    -----
    The fields do currently only describe a subset of character metrics
    information defined in the AFM standard.
    zThe character width (WX).zThe character name (N).zK
    The bbox of the character (B) as a tuple (*llx*, *lly*, *urx*, *ury*).c

    Parse the given filehandle for character metrics information and return
    the information as dicts.

    It is assumed that the file cursor is on the line behind
    'StartCharMetrics'.

    Returns
    -------
    ascii_d : dict
         A mapping "ASCII num of the character" to `.CharMetrics`.
    name_d : dict
         A mapping "character name" to `.CharMetrics`.

    Notes
    -----
    This function is incomplete per the standard, but thus far parses
    all the sample afm files tried.
