Hi Ronaldo:

Just apply a map formula, changing the value of your 0 (zero) pixels (black ones) to turn them into 255 (white), or whatever value should be black and white pixels. If that affects the contents of your map, apply a mask. In previous versions of ILWIS (DOS) it use to be an option to reverse this colors while printing, but I do not know if that is available now.

Good luck

Dear Ilwis users.I need to print one hundred of cut out counties areas. Well, after cut, one color composite image become black the cut area and it would spend a lot of ink to print. So, I´d like to have one way to become that black area in white.Thanks, Ronaldo de RossoEPAGRIFlorianópolis,Brasil
