Interface: MeasureProfile

Defined in: core/src/measure/FontkitMeasureContext.ts:60

How widths are computed from the font tables.

• 'advance' (default) — Σ per-code-point advanceWidth. Fast, and shaping-invariant, but ignores kerning and ligatures, so it drifts from what a browser paints (up to a few px per word on a kerned Latin font).
• 'shape' — fontkit layout() advance: GPOS kerning + GSUB (liga, clig, calt, ccmp), i.e. browser-default behaviour. Use for the SVG browser preset when on-screen width has to match the layout.
