ufoProcessor 1.0.3a1

Read, write and generate UFOs with designspace data.

ufoProcessor

Python package based on the designSpaceDocument from fontTools.designspaceLib) specifically to process and generate instances for UFO files, glyphs and other data.

• Collect source materials
• Provide mutators for specific glyphs, font info, kerning so that other tools can generate partial instances. Either from MutatorMath or fonttools varlib.model.
• Support designspace format 4 with layers.
• Apply avar-like designspace bending
• Apply rules
• Generate actual UFO instances in formats 2 and 3.
• Round geometry as requested
• Try to stay up to date with fontTools
• Baseclass for tools that need access to designspace data.

Usage

The easiest way to use ufoProcessor is to call build(designspacePath)

• documentPath: path to the designspace file.

• outputUFOFormatVersion: integer, 2, 3. Format for generated UFOs. Note: can be different from source UFO format.

• roundGeometry: bool, if the geometry needs to be rounded to whole integers. This affects glyphs, metrics, kerning, select font info.

• processRules: bool, when generating UFOs, execute designspace rules as swaps.

• logger: optional logger object.

• documentPath: filepath to the .designspace document

• outputUFOFormatVersion: ufo format for output, default is the current, so 3.

• useVarlib: True if you want the geometry to be generated with varLib.model instead of mutatorMath.
