Rotating some map types.

Nobody has claimed this yet.

Would it be possible to include a map rotation tool for some map types? Particularly isometric and hexagonal. I understand most tylesets won't allow this, but sim city 2000 style rotation ought to be possible with some tilesets.

In Sim City, the map was rotated by re-arranging the tiles. Most building sprites only had one orientation, so they did not rotate with the map, however in the case of sprites such as roads, hillsides, or power lines, the sprite would be replaced with an equivalent sprite of appropriate spacing.

Replicating this in Tiled would require these equivalent sprites be specified in the tile-set, but once that was set up, everything else could be a simple mathematical transformation.

Start by reviewing how Tiled represents isometric and hexagonal maps and how tilesets could specify equivalent sprites for rotation. Define the scope of the rotation tool and the required tileset metadata before implementation. Done means maps can be rotated where equivalent sprites are available while unsupported tilesets remain usable.
