PyGerber Bug Report

Mandatory checks

Before opening this issue:

• [x] I have reviewed the README for guidelines and haven't found a solution there.
• [x] I have reviewed the PyGerber documentation and haven't found a solution there.
• [x] I have reviewed the existing open issues and verified that this is not a duplicate.
• [x] I have reviewed the existing closed issues and verified that this was already resolved or marked as won't fix.
• [x] I have reviewed the existing pull requests and verified that this is not a already known issue.
• [x] I have reviewed the existing discussions and verified that this is not a already known issue.

To Reproduce

Load the attached file arctest2-F_Adhesive.txt and call GerberFile.from_file(file path).render_with_shapely() (Wouldn't let me upload a .gbr, so i changed it to .txt)

Expected behavior

Render succeeds

Additional context

This seems to happen with any file generated by KiCad which contains a filled circle. Non-filled circles work fine. Disabling the offending assert (or changing it from > to >=) doesn't seem to break things but does fix the issue.

Environment:

• Operating system: [Windows 10]
• Python version: [3.11]
• PyGerber version: [latest dev]

Optional checks

• [ ] I want to contribute example source files attached to this issue in the test suite of PyGerber for regression testing purposes.
• [ ] I want to include separate LICENSE file for resource files attached as a result of an agreement described in first checkbox in this section.
• [ ] I want to include separate README file for resource files attached as a result of an agreement described in first checkbox in this section.

Thanks for reporting this issue.

I am not sure what KiCad is trying to achieve with 0 degree arc, but fine by me if it works without that assert. To bypass it for now you can ignore assertions by passing-O flag to Python interpreter, I will change that on main soon.
