I'm using PSP 7 (I know it's old, but it serves my purposes).

I am resizing a bunch of images. PNG images with alpha transparency load with black backgrounds when I first open them. I have little experience with masks. I learned that I can do Masks > Load From Alpha Channel to see the transparent areas.

After loading the alpha channel, I resize the image. Usually, this works fine. However, sometimes the edges look a bit gray - kind of like if I made a transparent GIF on a gray background.

For the record, the box for Resize all layers is checked. If I uncheck that, the edges are black after resize. Also, the original images are already PNG-24 (16 million colors).

Here is the original viewed at 8x zoom (scaled in the browser to fit):



And here it is after reszing viewed at 8x zoom:



And here is the resized image viewed at 1x zoom:



It's probably not that noticeable to a lot of people, but the top edge does not look smooth to me.

Is there an easy way to fix this? Do I need to resize the mask separately?

The last one I had like this was a white circle. So I just cropped out the edges and added a white circle behind it. This one is a little harder.


Question: What were the questions and answers the Aelfinn gave to Moiraine?
Answer: Moiraine tells Egwene and Elayne in tSR that:


  "I could wager I know the face of the man I will marry better than either of you knows that of your future husband."
  
  [...]
  
  The Aes Sedai appeared regretful of having spoken. "Perhaps I only meant we share an ignorance. Do not read too much into a few words." She looked at Nynaeve consideringly. "Should I ever choose a man - should, I say - it will not be Lan. That much I will say."


This is before Rhuidean and the rings ter'angreal, so this knowledge could have come from the Aelfinn. Alternatively it could have come from a viewing by Min (for evidence, see the tEotW passage quoted by @DavidH in the comments), though I can't remember us ever seeing Min knowing about Moiraine and Thom in a Min-PoV chapter.
