Hi,

  Simply provide FT_Outline_Get_Bitmap() with a valid graylevel bitmap
and it'll invoke the AA rasterizer (ie. abitmap->pixel_mode ==
ft_pixel_mode_grays). Other bitmap fields are yours, the rasterizer will
use whatether pitch you defined. You are responsible for building the
FT_Bitmap object.

If you don't want/need to create your own bitmap instance (and setup its
8 fields :)), use FT_Load_Char() with FT_LOAD_RENDER. Of course this
implies that the outline is in a FT_Face ressource, which is maybe not
your case.
