Problem description:
Reading through the reference it states that or isometric maps the tiles width is all that matters then it takes half that for the height and anything over that is mainly for show. So if I have a 64x64 turf that means the bounding box automatically changes to 64x32?

I believe the default bounds are 32x32. You have to set the bounds yourself anyway, should work as intended.

Well, the term "bounding box" applies more to the physical rather than the visual. That is, if you were to look down on the map from above and just see a normal grid, the 64-wide icon format means that every tile is considered to be 64×64 pixels square. Pixel and step offsets are based on that, so pixel-x=32 means that the icon is half a tile over.
As far as the visual aspect of the map, yes, it's entirely accurate to say the base of the icon is only 64×32, and the remaining 32 pixels are overflow. (It's actually referred to as overflow in the code itself.) The SIDE_MAP format also uses an overflow concept; like isometric, its physical tiles are square, but the tiles as viewed can have a smaller Y dimension to allow for foreshortening. So when you design icons for isometric, you want to work from a diamond-shaped base that's half as high as it is wide. | |
