Instance Method

nextLayerId:layerPos:onAxis:direction:nextLayerId:layerPos:onAxis:direction:nextLayerId_layerPos_onAxis_direction_

Finds the nearest font master in one direction along an axis while keeping the other axis coordinates fixed.

Not available in Swift.

- (NSString *) nextLayerId:(CGFloat *) layerAxisLocation
                  layerPos:(CGFloat *) masterPos
                    onAxis:(NSInteger) axisIdx
                 direction:(int) direction;
nextLayerId_layerPos_onAxis_direction_(
    layerAxisLocation: float,
    masterPos: float,
    axisIdx: int,
    direction: int
) -> str

Parameters

layerAxisLocation

A buffer containing one internal coordinate for each font axis, in font axis order.

masterPos

On return, the coordinate of the matching font master on the selected axis when a match is found.

axisIdx

The index of the axis along which to search.

direction

A nonzero value whose sign selects greater or smaller coordinates.

Return Value

The matching font master identifier, or nil when no font master exists in that direction.
