由于以 .otf 结尾的文件可以是基于 TrueType 轮廓的 OpenType 字体或基于 CFF 轮廓的 OpenType 字体,因此不应使用文件扩展名来区分上述 OpenType 字体风格。另请注意,如果您采用现有字体并将文件扩展名从 .otf 更改为 .ttf,它的行为仍然相同,因此文件扩展名没有任何意义! 以下是官方 OpenType 规范对此的说明: “在...
TrueType 的「渲染提示」设计理念,特别是 Delta hint 是一把双刃剑:一方面它给予了设计师更高的自由度、更精细的控制,让 TrueType 格式的字体可以得到更高质量的优化,尤其是屏显优化[7];而另一方面,TrueType hinting 这种精确的、细致的调整,需耗费大量的时间和人力物力。尤其是 Delta hint,它只能适用于一个字体...
Consolidated “TrueType versus OpenType Layout” section into the “OpenType Layout at a glance” section. vdmx.htm In VDMX header, changed field name “offset” to “vdmxGroupOffsets”. vhea.htm Clarified scope of usage for the table. Changed type for the version field from Fixed to Version...
A quick note on some terminology used in this document. Microsoft prefers to call the TrueType engine a rasterizer while Apple® uses the term scaler. I’ll use the rasterizer term in this document. Apple also generally refers to the concept of applying the TrueType instruction set as “inst...
If the device space difference between this distance from the CVT and the single_width_value is smaller than the single_width_cut_in, then use the single_width_value rather than the outline or Control Value Table distance.MIRP measures distance relative to point rp0. More formally, MIRP ...

When a new type style is created of a different width class (either by a font designer or by some automated means) the relative aspect ratio of the glyphs in the new font is some percentage greater or less than the corresponding glyphs in the normal font — it is this difference that ...
Each subsequent point number in that run is stored as the difference between it and the previous point number. In subsequent runs, all elements, including the first, represent a difference from the last point number.Since the values in the packed data are all unsigned, point numbers will be ...
OpenType fonts support a slashed zero numeral format to emphasize the difference between the letter "O" and the numeral "0". The slashed zero numeral is often used for identifiers in financial and business information.The following text displays a sample order identifier using the Miramonte font....
