Properties
| Property | Type | Description |
|---|---|---|
cacheSize? | number | Experimental Maximum cached width entries (LRU). Default 20 000. |
measurer? | TextMeasurer | Experimental Measuring backend. Default: canvas when available, else the deterministic fallback. |
resolveFace? | ((face) => TextFace) | null | Experimental Maps a requested face to the face the measurer measures with. Default: for the canvas measurer, the face troika will actually draw (measurementFace: the registered family, the app's default font, or the built-in default font); identity for other measurers, so the deterministic fallback (node, tests) is unchanged. null forces identity. |
