I am trying to add a function to nasal, I have tried to look at the files indicated by the nasal website, but I can't seem to figure out how exactly I am supposed to go about it.
This function modifies an rgb texture using Magick++. I am using it to dynamically set the aircraft registration number.
Andy I bet you would be the one who's the most capable to help me here.

Thanks in advance,

Julien
