Hello!
I'm trying to use libfreetype.so via CFFI. What I hacked up so far is located here:
http://www.common-lisp.ru/cleft.asd http://www.common-lisp.ru/cleft.lisp
The code like that works:
(with-freetype lib (with-face lib (face "/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf") (docharmap (code face) (format t "~a " (code-char code)))))
and prints out all glyphs in a font.
However, the following doesn't do what I want:
(with-freetype lib (with-face lib (face "/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf") (set-char-size face (* 16 64) (* 16 64) 300 300) (glyph-pixarray face (char-code #\a))))
It returns #2A() Looks like the whole bitmap structure is set to zeros.
I think I'm following FreeType and CFFI tutorials closely and I can't explain what's wrong...
Thank you for your help, Dmitri
