It was a bit of luck that WoW coordinate system, at least as implemented previously in Maps, was merely a percentage of X or Y of the map, so long as the map was matching the actual area in the game.

For Raylan, is lucky because in another game, or movie, or book or whatever they could ignore the coordinate system if any or it was different, and still get a nice way to place markers on a map that most people would understand, like 50% and 50% is middle, and with the popup light-box it will tell them the number.

In WoW you will still have make sure to add a map 1 to 1 for crop and ratio, but not resolution, if you want the positions to match across maps and maybe the game, but only because of the game itself.

When I go look at the system in Witcher, if its flat like WildStar, where each map is relative to the other maps and not a percentage, then there will be a way to tell the layout engine. In WildStar for example the world is on one giant fixed coordinate system where one area starts at 2000,2000 and ends at 4000,4000 (numbers I'm making up) and you would be able to say what area that map belongs to.

If that were true, then even in map image file that were not orthogonal to the game world coordinates, you could specify where that map image file region maps to the stated world area and relieve a requirement on wow itself.
