Abstract Class: MeasureScope

Defined in: render/measure-scope.ts:15

Provides text-measurement primitives to any context that needs to know how wide a run of text will be before actually drawing it (e.g. for layout calculations, line-breaking, or positioning).

RenderContext implements this interface so nodes can measure text through the same object they use to draw — no separate measurement pass needed.
