Grdimage: "nan_transparent=True" doesn't work when "shading=True"

Q&A PyGMT Q&A

The following ERROR is returned:

grdimage [ERROR]: Option -Q: Cannot specify a transparent color for grids when intensities are also used

Is this desirable? Welcome comments / suggestions, thank you!

Hello Trevor.

I think that you are asking for a feauture that doesn’t exist.

Thanks for replying @Esteban82 – both “nan_transparent” and “shading” are still there (see image), but they don’t seem to be working together.

This is a PyGMT question and hence should posted under that category.

Sorry, I wasn’t clear.

Yes, both features exist but I think that they can’t be use at the same time.

Thanks @Esteban82 – that’s definitely a new “feature”. I’ll find a work-around.
Regards!

Hmm, would it work if you pass a semi-transparent grid to the drapegrid parameter of grdview?
