Axis definitions

Slice currently supports combinations of the following axis definition types in output fonts:

• Fixed instance locations
• Level 3 restricted axis ranges (must include original axis default value in the new, smaller axis range)^[1]
• Full, original variable axis ranges

Define your font axes with the syntax in the table below.

Axis definition	Axis Editor Syntax	Example
Fixed axis location	Integer or float value	400.0
Restricted axis range	Colon-delimited min:max integer or float range	200:700
Full axis range	Leave editor row blank	n/a

1: Default axis locations are required to compile valid variable font format files. The default axis value defined in the original font must be included in the restricted axis range due to the lack of compiler support for default axis location moves during the slicing process. We intend to support default axis location moves when it is possible to do so. This issue is being tracked on our GitHub tracker.
