I've updated the system to check-sum and log the "blobs" and I'm now able to efficiently position track and dump meaningful sprite frames to bmp files. You know all those sprite-sheets lying around on the internet, I'm now capable of building one of those about any sprite from a 16x16(the engine could be converted to cater for different tile sizes) tile-based top-down(it doesn't like parallax scrolling much!) game in minutes, and it'll probably include more frames! What's more, I can sequence the frames and give relative positional x,y offsets between them.
No more relying on inferior, poorly put together sprite-sheets for me!
