So, does any one know of some sort of maths(yes, Maths), that could be used to get a map from <a href="http://donjon.bin.sh/d20/dungeon/" rel="nofollow">http://donjon.bin.sh/d20/dungeon/</a> to align to the roll20 grid? I've tried everything I can thing of.

I have, but it seem to always be off and never returns a SQUARE value.

So, in my experience with the grid=align tool is it takes me ~3 iterations to get it just right. Especially on a map like the ones from donjon where the grid lines are multi-pixel so a little hard to get the center of. With three passes I was able to get the map lined up perfectly with the roll20 grid.

I had some luck making it a tile in masterplan and then re-saving it, just be sure and count the tiles and resize it in roll20 to that many spaces.
