A python tool to create a bigger image out of image tiles. pytiler is especially useful for building RPG maps from tilesets using conventional photo editing software such as Photoshop or GIMP. pytiler makes arbitrarily sized rectangular images out of a tileset so that you don't have to manually place every tile in your photo editor.
The simplest way to make a 4x2 image with a single tile is:
python pytiler.py 4 2 tile.png
Resulting in an image like this:

pytiler can also select from a group of tiles, and even randomly rotate them for a more natural look. See the usage for more details.
$python pytiler.py -h
usage: pytiler.py [-h] [-o OUT] [-t TILE_DIVS] [-r]
dims dims files [files ...]
positional arguments:
dims number of tiles in each direction
files input images to be tiled, randomly selected
optional arguments:
-h, --help show this help message and exit
-o OUT, --out OUT output image
-t TILE_DIVS, --tile-divs TILE_DIVS
tile subdivisions, usually to take care of alpha
borders
-r, --rotate randomly rotate the tiles
Some tilesets come with an alpha border, see 2-Minute Tabletop Dungeon Room Builder. pytiler handles these with the -t, --tile-divs option. For example, if you have a tile image that has an alpha border the same width as the width of the image, you would use -t 3 since the actual image is 1/3 of the total image length.
