PANOSE

PANOSE是一种依照字体外观来进行分类的方法。对于未知的字体，可以透过PANOSE体系将字体的外观特征整理并且与其他字体归类比较。

PANOSE定义了几个范围：Latin Text, Latin Script, Latin Decorative, Iconographic, Japanese Text, Cyrillic Text, Hebrew。PANOSE的原形在1985年由 Benjamin Bauermeister 所开发，当时一个字体由七个16进制数字所定义，现在则发展为十个。这每一个数字都定义一种视觉外观的单位，像是笔划的粗细或是字体衬线的样式。

图：Family，Serif Style和Proportion选项由Windows系统用来进行字体选择和匹配。

举例来说，Times New Roman字体，依照PANOSE系统的定义如下：

这十个选项的含义以及可以取的值（括号中给出）在下面列出。这些是最通常的情形，其“family”为2，Text and Display。（如果这第一个数字取值不同，那么剩余九个数字的含义也随之不同）。
