I'm trying to find an algorithm to render font outline. My goal is to create a texture filled with characters and to be able to create an outline for each character automatically. I was thinking of using FreeType lib to render each character to a surface/texture and then have a filter/algorithm to create outlines for them. I've been searching around for a while but I can't find anything about it. I'm using C++ (VC2005) and I do all the rendering with DirectX8, though the filter/algorithm can just as well be CPU based.
