Thanks LeviFiction, that works fine.
Shortly after posting I found Suz Shook's Tip #161 here:
http://suzsplace.com/tips&tricks/vi-tips161180.htm
Method 2 works (and its noted restrictions don't bother me for my intended application). But sadly I cannot get Method 1 to work. That method has an important potential advantage, as it would let me resize the selection
numerically in the Resize dialog. (As you may have guessed, the immediate application is my attempt to 'quarter' an image precisely, as described in my parallel post.)
When I follow Suz's instructions, I get the
whole image resized, not the selection.
I'd appreciate your advice on this please.
