GSLayer metricsValue:atHeight: | Glyphs API Documentation

func metricsValue(_ side: GSMetricNumbers, atHeight height: Int) -> CGFloat

- (CGFloat) metricsValue:(GSMetricNumbers) side atHeight:(NSInteger) height;

metricsValue_atHeight_(side: GSMetricNumbers, height: int) -> float

Parameters

side: The metric side to measure.
height: The coordinate at which to measure the side bearing.

Discussion

For horizontal side bearings, the height is a y coordinate. For vertical side bearings, the height is an x coordinate. Returns NSNotFound when no value can be measured.
