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.

Draw your larger selection and save it to a channel.
Check the "Expand from center" option in the tool's Option dialog
and
then click inside the selection to activate the drag handles[*]. Use
the handles to resize your rectangle.
Invert your selection and then intersect it with the previously saved
channel (CTL+SHIFT the red button next to the trashcan in the Channels
dialog).
[*] Even though the handles might be visible, they are not actually
active after a "Select->Save to channel" is performed (this is
probably a bug).

Here's a simpler method (no need for saving to a channel) that I
thought would work, but doesn't, and I'm not clear why:
1. Make the first selection. Click inside the rectangle to confirm it.
2. In the Rect Select tool options, switch to Subtract mode, Expand
from Center, and Fixed Aspect Ratio (current).
3. Click in the rectangle again to bring back the resize handles.
4. Resize to define the smaller rectangle (which will be subtracted
from the larger one.
The problem: when you first start the drag from a resize handle in
step 4, the boundaries jump to a rectangle that's not concentric
with the current one, with the positions seemingly random (at least,
I can't see any regularity to which handle creates jumps in which
direction).
Is that a bug? If it's not, why does it happen? (I'm seeing this
with the Ubuntu gimp 2.4.5.)
