Interpolates a master for an instance.

func interpolateFontMaster(_ instance: GSInstance, scale: CGFloat, thin: Bool) throws -> GSFontMaster
- (GSFontMaster *) interpolateFontMaster:(GSInstance *) instance scale:(CGFloat) scale thin:(BOOL) thin error:(NSError **) error;
interpolateFontMaster_scale_thin_error_(instance: GSInstance, scale: float, thin: bool) -> tuple[GSFontMaster, NSError]

Parameters

scale

The scale applied to interpolated metrics and outlines.

thin

Pass YES when generating a lightweight preview master.

Parameters

scale

The scale applied to interpolated metrics and outlines.
