@rivetgeek@theboatend Yeah, not ideal. Grey-scale shading on line art is going to make it tough to automate. I’ve used this AI https://www.upscale.media for basic work, but I doubt it will produce acceptable results from this example. I agree with @theboatend that hand redrawing of some kind is the best option (if you don’t want to start from scratch on simple elements like compass roses).
