I have this same question since I'm investigating going away from Photoshop and it's subscription model.
In my batch processing, I like to resize photos independent of their orientation (portrait or landscape). In photoshop, this is done via File/Automate/Fit Image.
For my macro, I:
Resize to 4x6
Save 4x6-Print folder
Resize to 640 (for web)
Add a copy-right water mark
Save to "Web" folder
Is there a way to resize images in Affinity in this same way independent of their orientation?
(Please don't point me to a page with 100s of tutorial videos, I only have 10 days of a trial period to figure this out.)
