A python script to convert images into lua for factorio world generation. Requires Pillow.
Put the image to convert into the same directory as the script and run:
img2factorio.py <image>
When ran, the script checks which pixels in the image are closer to black than white and maps those (x,y) coordinates to a lua table. A new scenario under %APPDATA%/Factorio/scenarios/<image> is created in which the surface tiles that match those black pixels are replaced by void.
Note: The rsc\simple-tile.lua file provides the code used to tile the image on chunk generation. It is copied to the scenario's control.lua file and variables width, height and img_table are appended to the end by the python code.
| Argument | Description |
|---|---|
| --scale <coef> | scale the image and maintain the aspect ratio |
| --width <pixels> | set the image width in pixels |
| --height <pixels> | set the image height in pixels |
| --border <thickness> | add a border around all edges of the image |
| --quantize <number> | quantize the image colours into a limited number |
| --threshold <value> | alter the greyscale value threshold pixels are compared to |
| -c, --color | use custom tile associations in colors.py |
| -i, --invert | invert the image colours |
| -t, --tile | make the image seamless |
| -p, --preview | save a preview image and exit |
This script was just something I wrote for my own entertainment and not intended to be perfectly optimised or idiot-proofed, but if you'd like to submit a PR or issue it's more than welcome.
