Sorry for the delay of response. I work until about 5:00ish every day, and I am just now getting on to reply and play around with Affinity some more. I am new to all of this (editing program for digital images), so the learning curve is huge. Thank you for your patience and time.
I did what both of you suggested. It seems you were correct, Carl - my image was so large that I could not see the control handles. I got down this rabbit hole by wanting to resize my images so that they were appropriate for social media posting. I watched a couple of YouTube videos on it, and I could not figure out where those blue handles were! Then I started reading threads on this Affinity forum.
A couple more questions:
Is my canvas supposed to be checkerboard or plain white? I have plain white, but I see checkerboard in videos.
I did the unclip canvas as suggested and now have a blue line across the canvas. I can seem to get rid of that. What does that mean?
This is a raw image BTW.
