Sprite Sheet Mapper

Sprite sheet mapper is a very simple application that lets you easily map your sprite sheet images into a json file.

With it you can select section of your image,  and if that row is an animation, its length and frame duration.

The mapping is saved in a easily to use json format that you can then import on your game.
