用元编程方法设计可变字体，实现参数化字型生成。
Parametric type design in the era of variable and color fonts
- 基于MetaPost构建参数化字体设计流程
- 开发并开源两款可变字体作品
- 为现代字型设计提供可复用的程序化方案
参数化字体是通过程序定义、包含可变参数的字体，由唐纳德·克努斯在1980年代以MetaFont技术开创。尽管其理念常被视为图形用户界面时代前的遗留技术，但近年来可变字体的发展暗示了相关原理的复兴。本文探讨一种基于参数化设计原则的现代字体创作流程，特别采用MetaPost实现。作者利用该方法创建了两款可变字体，并以自由开源许可发布。论文详细阐述了方法论、工作流及实践中的关键洞见。
原文摘要 · Abstract (English)
Parametric fonts are programatically defined fonts with variable parameters, pioneered by Donald Kunth with his MetaFont technology in the 1980s. While Donald Knuth's ideas in MetaFont and subsequently in MetaPost are often seen as legacy techniques from the pre-graphical user interface (GUI) era of type design, recent trends like variable fonts suggest a resurgence of certain principles. This paper explores a modern type design process built on parametric design principles, specifically using MetaPost. The author created two variable fonts with this method and released them under a free, open-source license. The paper details the methodology, workflow, and insights gained from this process.
