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.
