I've got a rectangle selection. Now, I am trying to do a subtractive selection within that rectangular selection, to make a sort of picture frame selection. The problem is that I'm having trouble getting the inner, substractive selection centered within the first rectangle.

When I use the ctrl key while selecting, it grows a rectangle and I can't figure out where to start the growth so it is centered. Very hard to do.

When I try to use the tool settings dialog to push the subtractive selection option, the selection doesn't even seem to work?

Any solutions?

Gimp 2.2.13, Debian linux

thanks, Chad

Very common procedure (making a frame). I use this method to make an antialiased line around things:

1. Create a rectangular selection. 2. Fill with color
3. Shrink selection by X pixels (where x is the width of the border you want)
4. Cut selection (or fill with background color, etc.).

Alternatively, use the Tool Options dialog for the selection tool and set the Size and Position fields manually for the second selection. The first method works for small width borders but because shrink will slowly round the corners it doesn't work well for larger width borders. The second method works perfectly for all width borders.
