AD inverting mask layer ? in Affinity on iPad Questions Posted February 18 Is there any way to invert a mask layer in Affinity Designer on iPad? I have seen several topic regarding how it gets done in Affinity Photo (using channel mode, which I can’t find its counterpart in Designer) but I want to do this in Affinity Designer and am still pretty puzzled. Also I’m having a hard time inverting a selection, too. I do it by tracing and then set it to outer line mode and widening pixels.. and I couldn’t help but thinking there may be more simple way as in Photoshop etc..
