"""cffLib: read/write Adobe CFF fonts
|
||
|
|
|
||
|
|
OpenType fonts with PostScript outlines contain a completely independent
|
||
|
|
font file, Adobe's *Compact Font Format*. So dealing with OpenType fonts
|
||
|
|
requires also dealing with CFF. This module allows you to read and write
|
||
|
|
fonts written in the CFF format.
|
||
|
|
|
||
|
|
In 2016, OpenType 1.8 introduced the `CFF2 <https://docs.microsoft.com/en-us/typography/opentype/spec/cff2>`_
|
||
|
|
format which, along with other changes, extended the CFF format to deal with
|
||
|
|
the demands of variable fonts. This module parses both original CFF and CFF2.
