Instance Method

interpolateFull:masters:scale:keepSmart:layerName:additionalLayers:error:interpolateFull:masters:scale:keepSmart:layerName:additionalLayers:error:interpolateFull_masters_scale_keepSmart_layerName_additionalLayers_error_

A detached layer interpolated for an instance, or nil when interpolation fails.

Not available in Swift.

- (GSLayer *) interpolateFull:(GSInstance *) instance masters:(NSArray *) masters scale:(CGFloat) scale keepSmart:(BOOL) keepSmart layerName:(NSString *) layerName additionalLayers:(NSMutableArray *) additionalLayers error:(NSError **) error;
interpolateFull_masters_scale_keepSmart_layerName_additionalLayers_error_(instance: GSInstance, masters: list, scale: float, keepSmart: bool, layerName: str, additionalLayers: list) -> tuple[GSLayer, NSError]

Parameters

instance

The instance that supplies the interpolation location and settings.

masters

The font masters participating in the interpolation.

scale

The coordinate scale applied to the result.

keepSmart

Whether Smart Components remain components when possible.

layerName

The name of corresponding source layers to interpolate, or nil for the primary layers.

additionalLayers

A collection to which interpolated color and corner layers are appended, or nil when they are not needed.

error

On return, an error that prevented interpolation.

Discussion

This method accounts for active Intermediate and Alternative layers, Smart Components, and pre-interpolation filters. The source layers must have matching structure.
