hi @andreeco, thanks for the contribution to this project! The SVG configuration looks great.

This repository hasn't been actively maintained for some time, and I just updated the workflow. The test errors are likely caused by dependency issues with ZBar.jl.

It would be great if you could help resolve this issue as well (perhaps in a separate PR), or I need some time to fix it myself before merging this PR.

Can this be merged? The package has grown stale and there are compatibility issues. The pull request fixes these issues.

Sorry @RexWzh, I didn’t notice your post earlier. I’d be glad if you could take it on. You’re more familiar with the source code and have a better understanding of it and it's dependencies. The issue is that this depends on that, and that depends on this.

I can run the tests without errors, but I had to manually install some packages with apt.
