I'd use select by color. It's easier to put in a script than magic wand
When you say circle, do you mean an actual, geometric circle? (or as
close as you can approximate with pixels) If you just want a rounded
border, and if the blue isn't next to the edge of the screen, here's a
1. Select by color 0,0,255 (if you want deep blue)
2. Grow selection by x pixels.
3. Shrink selection by x pixels.
Where "x" is an arbitrary value. The higher "x" is, the more rounded the
border will be, but, if your image is within "x" pixels of any edge of the
screen, then you end up cutting off some of your blue.
