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 has no external dependencies: >>> import matplotlib as mpl >>> from pathlib import Path >>> afm_path = Path(mpl.get_data_path(), 'fonts', 'afm', 'ptmr8a.afm') >>> >>> from matplotlib._afm import AFM >>> with afm_path.open('rb') as fh: ... afm = AFM(fh) >>> afm.get_fontname() 'Times-Roman' 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.
