cffLib: Read and write Adobe CFF fonts
Overview:
cffLib: read/write Adobe CFF fonts
OpenType fonts with PostScript outlines embed a completely independent font file in 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 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.
Submodules:
cffLib contains submodules for converting between CCF and CFF2.
Each can be used within other Python scripts or run as a
subcommand of the fonttools
command-line tool:
It also contains submodules for manipulating CFF-formatted glyphs:
Module members:
- class fontTools.cffLib.CFFFontSet[source]
Bases:
object
A CFF font “file” can contain more than one font, although this is extremely rare (and not allowed within OpenType fonts).
This class is the entry point for parsing a CFF table. To actually manipulate the data inside the CFF font, you will want to access the
CFFFontSet
’sTopDict
object. To do this, aCFFFontSet
object can either be treated as a dictionary (with appropriatekeys()
andvalues()
methods) mapping font names toTopDict
objects, or as a list.from fontTools import ttLib tt = ttLib.TTFont("Tests/cffLib/data/LinLibertine_RBI.otf") tt["CFF "].cff # <fontTools.cffLib.CFFFontSet object at 0x101e24c90> tt["CFF "].cff[0] # Here's your actual font data # <fontTools.cffLib.TopDict object at 0x1020f1fd0>
- decompile(file, otFont, isCFF2=None)[source]
Parse a binary CFF file into an internal representation.
file
should be a file handle object.otFont
is the top-levelfontTools.ttLib.ttFont.TTFont
object containing this CFF file.If
isCFF2
is passed and set toTrue
orFalse
, then the library makes an assertion that the CFF header is of the appropriate version.
- compile(file, otFont, isCFF2=None)[source]
Write the object back into binary representation onto the given file.

Helper class for writing the CharStrings INDEX to binary.
- class fontTools.cffLib.Index(file=None, isCFF2=None)[source]
Bases:
object
This class represents what the CFF spec calls an INDEX (an array of variable-sized objects). Index items can be addressed and set using Python list indexing.

IndexCompiler
- class fontTools.cffLib.GlobalSubrsIndex(file=None, globalSubrs=None, private=None, fdSelect=None, fdArray=None, isCFF2=None)[source]
Bases:
Index
This index contains all the global subroutines in the font. A global subroutine is a set of
CharString
data which is accessible to any glyph in the font, and are used to store repeated instructions - for example, components may be encoded as global subroutines, but so could hinting instructions.Remember that when interpreting a
callgsubr
instruction (or indeed acallsubr
instruction) that you will need to add the “subroutine number bias” to number given:tt = ttLib.TTFont("Almendra-Bold.otf") u = tt["CFF "].cff[0].CharStrings["udieresis"] u.decompile() u.toXML(XMLWriter(sys.stdout)) # <some stuff> # -64 callgsubr <-- Subroutine which implements the dieresis mark # <other stuff> tt["CFF "].cff[0].GlobalSubrs[-64] # <-- WRONG # <T2CharString (bytecode) at 103451d10> tt["CFF "].cff[0].GlobalSubrs[-64 + 107] # <-- RIGHT # <T2CharString (source) at 103451390>
(“The bias applied depends on the number of subrs (gsubrs). If the number of subrs (gsubrs) is less than 1240, the bias is 107. Otherwise if it is less than 33900, it is 1131; otherwise it is 32768.”, Subroutine Operators <https://docs.microsoft.com/en-us/typography/opentype/otspec180/cff2charstr#section4.4>)

object
The
CharStrings
in the font represent the instructions for drawing each glyph. This object presents a dictionary interface to the font’s CharStrings, indexed by glyph name:tt["CFF "].cff[0].CharStrings["a"] # <T2CharString (bytecode) at 103451e90>
See

A delta list with blend lists has to be all blend lists.
The value is a list is arranged as follows:

V
is the absolute coordinate value from the default font, andd0-dn
are the delta values from the n regions. EachV
is an absolute coordinate from the default font.We want to return a list:
[ [v0, v1..vm] [d0..dn] ... [d0..dn] numBlends blendOp ]
where each
v
is relative to the previous default font value.
