# Rotate tiles

This tool can be used to transform an image containing a tileset into a new
one with a single column of tiles, so can be loaded with ".incpng" and the
result is easy to index.

For example, given 6 tiles of 8x8 pixels in `origin.ong`:

```
012345
```

The command `./rotate.py origin.png 8 8 dest.png` will generate an image with
the tiles rearranged like this:

```
0
1
2
3
4
5
```

In this way tile 0 is in `addr`, tile 1 in `addr + 64`, tile 2 in `addr + 128`, etc.

## Requirements

The tool requires:

- Python 3
- PIL (or Pillow)

For example, you can install Pillow with:

```
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
```
