Well, the mathematics is the sampling theorem. As I say in my page, what is needed is to model the image as a function of (x, y) where x and y are reals (and not integers). That function needs to be filtered to honor the sampling theorem before sampling. I'm also sampling at (approximate) subpixel positions.
I understand, but in principle that's what every rasterizer does. Well, not all do it as correctly or precisely as they could, but the principle is the same. From what I can see you seem to be doing it quite precisely, but this is definitely not trivial, at least if you also want it to be fast. Thus my question about the precise method used.
Also, you show a demo of an image where the seams are not shown. Did you render the all objects to the same buffer or are you able to composite them seamlessly (without having problems with overlaps). And in either case, how did you make this efficient.
BTW, why is there also a color difference between your images and Inkscape.
There should be none. Where do you see it?
For example the lion demo on your site. The two versions have very clearly different colors on my monitor. (Perhaps there's an issue with gamma or color profile settings...)
