我必须使用字体路径吗？
Must I use path to fonts?
FT_New_Face 函数似乎是我要找的函数，但它需要字体文件的路径。我想在不提供路径的情况下打开 "Times New Roman," 之类的字体。我该怎么做？
大多数基于 unix 的系统使用 Fontconfig 来从一组搜索参数（家族名称、变体、重量等）中获得最匹配的字体文件
Fontconfig is a library for configuring and customizing font access.
Fontconfig can:
- discover new fonts when installed automatically, removing a common
source of configuration problems.
- perform font name substitution, so that appropriate alternative fonts can be selected if fonts are missing.
- identify the set of fonts required to completely cover a set
of languages.
- have GUI configuration tools built as it uses an XML-based configuration file (though with autodiscovery, we believe
this need is minimized).
- efficiently and quickly find the fonts you
need among the set of fonts you have installed, even if you have
installed thousands of fonts, while minimzing memory usage.
- be used in concert with the X Render Extension and FreeType to implement high quality, anti-aliased and subpixel rendered text on a display.
Fontconfig does not:
- render the fonts themselves (this is left to FreeType or other
rendering mechanisms)
- depend on the X Window System in any fashion, so
that printer only applications do not have such dependencies
Fontconfig 相对便携，可用于各种系统，但是 OSX 具有 CoreText which has similar functionality and Windows has DirectWrite
