libschrift

libschrift is a lightweight TrueType font rendering library.

It can be seen as a much smaller, but more limited alternative to FreeType2.

Specifically, libschrift aims to:

  • Be as simple and easy-to-use as possible. See: https://www.suckless.org/philosophy/
  • Make correct (as in artifact-free, Unicode-aware etc.) font rendering easy to achieve.
  • Be reasonably secure, which especially means to not crash, leak memory / resources or expose major security vulnerabilities on corrupted / malicious / random inputs.

Limitations

  • Unicode is the only supported text encoding.
  • Support for most TrueType (.ttf) and certain OpenType (.otf) fonts. No bitmap or PostScript fonts.
  • No hinting. Especially no auto-hinting like FreeType2.

Documentation

For documentation on how to use libschrift in your own programs, refer to the schrift(3) man page, the source code of the bundled demo, as well as the header file schrift.h.

You can also view the man page in your browser at http://tomolt.github.io/libschrift/

Progress

In terms of security and performance, libschrift is already pretty solid. However, it is still missing some important features, like right-to-left text support.
