Hello!!
I have been using Bluebeam for a decent while, and anything I have trouble with I can usually sort out on my own, but I am stumped. We have a set of plans, all of which are images with a peach-coloured background. To save on ink, I need to change them to grayscale, ideally. Please see the attached screenshot. It appears in the thumbnail to work, but when pressing ok nothing changes.
Any help would be greatly appreciated.
