We don't have one :-) Anyone out there who uses it, probably posting a
snippet?
    

It is as simple as:

FT_Load_Glyph( face, gindex, FT_LOAD_DEFAULT );
if ( face->slot->format == FT_GLYPH_FORMAT_OUTLINE )
	FT_Outline_Embolden( &slot->outline, strength );

Other outline related functions can be used in the same way.  Although
not documented, it is safe to manipulate the points of slot->outline
directly. (not 100% sure though :-)

It is not true for slot->bitmap btw.

  

I confirm that, once loaded, you can transform/distort/embolden the outline if you
want to. You should not *free* it however with FT_Done_Outline, because its
pointers might point to arrays owned by a distinct object (e.g. FT_GlyphLoader
objects)

As for slot->bitmap, you shouldn't do anything with them, except read them, since
its buffer address can point to a memory-mapped file directly.

Hope this helps,
