Curvature combs and harmonized paths in MetaPost

Abstract

Most font editors offer curvature-related tools. One of these tools is the visualization of curvature via curvature combs . Another tool is the so-called har-monization , which makes the curvature continuous along paths. An implementation of both tools in METAPOST will be presented. Curvature-optimized paths already play a significant role in METAFONT and METAPOST and therefore example METAPOST paths will be examined for their curvature behavior.
