Density Map in BYOND Discussion
No, it wouldn't, you didn't understand. You'd have the DMI data, but you wouldn't be able to intuitively actually access the icons themselves, i.e. isolate each graphical parts. That would need to be implemented in the language, like you can already isolate an icon_state and dir for instance with new /icon(file,state,dir), you'd need some method (probably the same) to isolate animation frames and whatnot.
I made a program that saves/loads similar maps, and it only took about two hours to write. My format is really similar, except it only supports one turf, area, obj, and mob per tile ('cause I was lazy, and that's all I needed).
