I recently extracted some PDF's for use in an upcoming campaign. Unfortunately there is a big blank spot in one of the maps i intend to use. No problem there as I cropped out a section of another map to overlay the blank spot, but I can't seem to be able to merge the photos into one seamless piece. On the GM view everything looks right but when I switch to the player's view the blank spot is still there. Is there a way to merge the two photos so that I and the players will be able to see it?
