Sounds like the only difference from what your suggesting and what I am doing is where the box filter is done. I save a tga at 2x size and use Photoshop to scale it down. Doing the scale in code would offer one big advantage, less memory required since I would only have to allocate memory for the image size needed and not the 2x version. However if I box filter the tiles, I might still get some artifacts along the edges. Filtering the whole pieced back together image in code wouldn’t gain me anything.
My case is not exactly the same as gavinb posted about since I am making an image for export or sending to the printer. For the printer case I do scale after the image is pieced together. I do get quite good results except for the hefty memory demands but it is mostly used in house for making posters.
