Hello,

Since the new version v1.3.2-x64 of aseprite, we can now generate a Tilemap with tile’s flip property.

But it seems that when I want to retrieve, through API, the ID of the tile in question, the ID is a very large number that doesn’t correspond to anything.

The method used to retrieve ID is: tilemap:getPixel(x, y) with X, and Y the tile position in the Tilemap.

 ![example](https://community.aseprite.org/uploads/default/original/3X/3/f/3fcb4fd41eb81015d887625e39cf2eb78e313f2e.png)

Is there a way to get the Tile ID and if it’s mirrored ?

Thanks in advance.

I’d try `app.pixelColor.tileI` and `app.pixelColor.tileF`, which decompose a map entry into its index and flipping flags. `app.pixelColor.tile` composes an index with its flipping flags to create a complete map entry.

The flipping flags for X, Y and D can be found in the source code, as well as the logic for how the functions above work:

The flags are the same as in Tiled, btw, which makes export nice and easy:

oh, this is very good !  
With app.pixelColor.tileI and app.pixelColor.tileF I can now retrieve all informations I need for my lua script.

Maybe the official API documentation will write this type of usage.  
Tiles management is still fairly new in software.

Thanks.
