2D images become non-pickable after changing cmap

[sudmat]

Hi, I found a strange thing when running the spline_draw example.

Below is the officially provided code (vedo\examples\advanced\spline_draw.py) which works fine.

But when I changed the pic cmap to binary_r, I could no longer select the points on the image because the event.actor became None.

I am not sure if this is a feature or bug, but it seems not making sense if the pickability depends on the cmap. Any information would be appreciated!

This is quite strange ! I don't understand why that happens.. one possible way around is to create a quad mesh from the image, and that works:

pic.cmap("binary_r")
pic = pic.tomesh()

Thank you and I'll try!
