Yesterday I posted a request for advice about either Affinity Photo or Pixelmator Pro. You can see the specifics in this post: https://robinkingfaces.com/2021/11/25/do-you-use-affinity-photo-pixelmator-pro-is-this-possible-thats-all-i-need-to-know/
Thanks to Phil Perkins – Perkins Designs – I was able to do exactly what I wanted, using Affinity Photo. Thank you, Phil!! And thank you, also, to Ed Ritchie – eRitchieart – for letting me know that I can do the same thing using Pixelmator Pro. I haven’t had an opportunity to try that yet but I’m sure it’ll go well. Thank you, Ed Ritchie!!
