  Automatically embedding pixel art in QR-codes.


  

  

  



←example output


## Setup and usage:

- sudo apt install python3-dev python3-setuptools python3-pip libzbar0 libzbar-dev

- pip3 install -r requirements.txt

**usage:** ./qrvanity.py input.png "encoded message"


**output:** one or multiple output.png


**input format:** pixel art as small black and white binary image (no grayscales)


**advice:**

- Use transparent pixels where you don't care (outside the motive if it has non-rectangular borders). It will then occupy less data modules (QR-code pixels) and the resulting QR-code will be smaller.

- Drawing a white border around black motives will improve visibility, because it keeps black data modules away.

- The tool may often generate QR-codes that are not strictly valid according to specifications but can nevertheless be read by most QR-code readers.
