Function: makeRegistryResolver()

makeRegistryResolver(registry, onHeuristic?): MetricsResolver

A MetricsResolver backed by a registry: exact metrics for a registered face, otherwise the shared heuristic fallback (with onHeuristic told which face it stood in for). A run with no fontFace at all resolves to undefined, which the callers treat as unmeasurable.

Parameters

Parameter	Type
registry	FontMetricsRegistry
onHeuristic?	(face) => void

Returns

MetricsResolver
