What are tilemaps?

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.

What does this app do?

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.

Notes

• Input image must be a png or gif
• Input size must be dividable by the tile size
