cl-freetype2

cl-freetype2
============

This is a general Freetype 2 wrapper for Common Lisp using CFFI.  It's
geared toward both using Freetype directly by providing a simplified
API, as well as providing access to the underlying C structures and
functions for use with other libraries which may also use Freetype.

Platform
--------

Confirmed working:

* SBCL
* Clozure
* CLISP (with CVS libffcall only, otherwise callbacks don't work)

Confirmed not working:

* ECL (CFFI doesn't load)
* ABCL (CFFI loads, but can't grovel?)

Documentation
-------------

See `doc/cl-freetype2.html` for complete documentation.

Example
-------

An example using the toy interface:

    (defparameter *face* (new-face "/usr/share/fonts/corefonts/times.ttf"))

    ;; Set the size to 24 points and 72 DPI
    (set-char-size *face* (* 24 64) 0 72 72)

    ;; Trivial output:
    (print-with-face *face* "Hello")

    ;; Output (if this doesn't display, make sure your encoding is
    ;; set to UTF-8):
