62 | | -Other font specifications which Matplotlib supports: |
63 | | -
|
64 | | -- Type 42 fonts (PS): |
65 | | -
|
66 | | - - PostScript wrapper around TrueType fonts |
67 | | - - 42 is the `Answer to Life, the Universe, and Everything! |
68 | | - <https://en.wikipedia.org/wiki/Answer_to_Life,_the_Universe,_and_Everything>`_ |
69 | | - - Matplotlib uses the external library |
70 | | - `fontTools <https://github.com/fonttools/fonttools>`__ to subset these types of |
71 | | - fonts |
72 | | -
|
73 | | -- OpenType fonts: |
74 | | -
|
75 | | - - OpenType is a new standard for digital type fonts, developed jointly by |
76 | | - Adobe and Microsoft |
77 | | - - Generally contain a much larger character set! |
78 | | - - Limited support with Matplotlib |
| 58 | +Matplotlib also provides limited support for OpenType fonts, a newer standard |
| 59 | +developed jointly by Adobe and Microsoft; such fonts generally contain a much |
| 60 | +larger character set. |
