This is a great way to add metadata to our images just through the file name. We might also consider adding metadata to the jpeg itself, perhaps containing much of the pyvista.Report(), but having it there in the file name might be enough.

Didn't know that was possible. Will try adding that. I think this will cause GPUInfo to be called twice though, which is not ideal.

Here's some sample image names generated from pyvista/pyvista#7914. There's a small issue with "-CI" including a dash when it shouldn't.

VTK Dev:

macOS

Will leave this for a separate PR, and after #213 is implemented, because the unit tests save PNGs, but the doc tests save JPGs, so storing the metadata will need to consider both formats.

Thanks for the responsive implementation

I added a few suggestions, would be happy to contribute if not being clear.

[user27182]

@beroda I believe all comments should now be resolved.

The env_info name could be improved #214 (comment) but overall LGTM.
