Greetings, I am mosaicking a georeference image and have it almost complete, but I would like to fill in the gaps between two of my images. I would prefer to use the cutline feathering option, however Im a bit frustrated by the procedure. I know I need to use a polyline annotation to define the area I want to "cut out" but how do I figure out the where that area is exactly in my image. The tutorials are not helping me either, so any advice from someone with experience would be a lifesaver! Thanks -Linda
