v24 applying an image mask in ENVI

[@annelies1229]

Hey, I want to mask out clouds and urban areas from my Ali image. Do you have any idea how to invert the mask proces? I have a polygon of my clouds and urban areas, but if I do a mask, these areas get a value of 1 and the rest of the image a value of 0. I want it the other way around. Do you know how to do this? Kind regards
