saving colored mesh to .png

Hi Marco, thanks for this wonderful package!

We are working on a project very similar the pic below. However, after we use the .pointColors to successfully add colors to the region, is there any way to automatically take a 2d snapshot with it and save as .png/.jpg by script?

(resource from: https://github.com/mikedh/trimesh/issues/966)

To put it into code, it works well if doing this way:

vtk_diff.pointColors(scal, cmap='rainbow').addScalarBar()
vtkplotter.show(vtk_diff, bg="white", axes=0, interactive=True)

However, when we are trying to get the 2d snapshot in the way below, it does not work:

plt = vedo.Plotter(shape=custom_shape)
vtk_diff.pointColors(scal, cmap='rainbow').addScalarBar()
plt.show(vtk_diff.c('lb'), interactive=False, at=0)

May we know what we should modify based on the current code? Thx!

you must have an older version, do pip install vedo -U

Updating vedo (2022.0.1 -> 2022.1.0)

thank you a lot, it’s work I hope it will work with my docker Linux (no interface)
