I have downloaded Blender's source code and looked at it. There's really a function in there that anti-aliases an image that only consists of black or white pixels....
It would be a nice exercise to convert this to a Fuse (for those of you who are new to Fusion: It's a script plugin written in LUA and optionally OpenCL that is supported by the free version of Fusion 7.5)
I've pasted the algorithm over at
http://www.steakunderwater.com/wesuckle ... 1077#p1077Anybody who's interested in learning about Fusion's excellent Fuse API is invited to take a look. We're currently building a learning resource where small tools like this would be programmed in a community effort and each step and improvement to the code is fleshed out in public.
