Quick way to extract tiles from a tilemap
Tilemaps have been heavily used in the earlier computer games and are still a great memory preserving way to deal with very large worlds. They are made up of small tiles like 8x8 or 16x16 pixels. Check wikipedia.
This app takes a level design and tries to extract the tiles that were used to built it.
You can define a tolerance that allows the app to merge tiles that are just a few pixels off.
If successful, you can download the tiles as a png and a map.json containing the map data. Check out the demo button that explains a lot.
