libschrift
==========
*libschrift* is a lightweight TrueType font rendering library.

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.

Features
--------
- Unicode support
- Very small! (~1500 LoC)
- No dependencies on anything other than the C standard library
  (POSIX / WINAPI are only used for memory mapping, which is not essential)
- Compatible with any C99 compiler
- Highly portable! Some versions have been tested on
  Linux, OpenBSD, FreeBSD, Windows, iOS, and macOS!

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 as found in FreeType2.
- No color emojis.

Building
--------
On **Unix-like systems** including Mac OS, you can use `make && make install`
to install libschrift as a system-wide library. Since it is statically linked,
you only need the library files for development.
Users of your projects do not need to install libschrift.

On **Windows**, you can either use the provided MSVC project,
or compile with make via MSYS, or simply compile manually.

**Alternatively**, you can always copy-paste `schrift.c` and `schrift.h` into your
own projects source folder.

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

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

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

Visual Quality
