Anatomy of a Font. Visualise metrics.

Import the anatomy package:

#import "@preview/anatomy:0.1.0": metrics

Samples

Additionally, a closure using metrics dictionary as parameter can be specified for further typesetting:

metrics(54pt, "一點明體", "電傳打字機",

Tested with metrics(54pt, "Hiragino Mincho ProN", "テレタイプ端末"):
