# FreeType-2.9.1 API Reference

# The auto-hinter

While FreeType's auto-hinter doesn't expose API functions by itself, it is possible to control its behaviour with FT_Property_Set and FT_Property_Get. The following lists the available properties together with the necessary macros and structures.

Note that the auto-hinter's module name is ‘autofitter’ for historical reasons.

Available properties are increase-x-height, no-stem-darkening (experimental), darkening-parameters (experimental), warping (experimental), glyph-to-script-map (experimental), fallback-script (experimental), and default-script (experimental), as documented in the ‘Driver properties’ section.
