Thank you gwpriester for you interesting suggestion. And thank you handrawn for
the bad news
Interestingly, if you review the Affinity Photo forum(s) you'll find that
"pixel" selection is a problem with several plugins there too. Just like Xara,
some plugins work with AP, some don't and there are issue(s) with the ones that
do work. I did get AP for what I could do with its native filters alone. Considering
the cost of 64bit plugins AP is a bargin forget about plugins for it
Overall, so very grateful I discovered Xara and this wonderful community of Xara
enthusiasts and artists.
