@jonasschnelli Good addition. I incorporated this in the default PNG writer as an option. Also, now if no logo is present, the default will be set to 16 colors (which can be overridden via the options). Thank you! |

I had to use 2 color, 1 bit per pixel (1BPP) PNG for a project.
The current default is a 24-bit PNG, which is eventually not ideal for a just black and white QRCode.
Maybe this is useful.
Happy to adapt the PR if someone has a better approach.
