Make an object thinner without scaling it

Make an object thinner without scaling it
Hi

I am designing a logo, and have used a gimp script to create (a) the text that I need, and (b) a ring to enclose it. The ring is in a separate layer with a transparent background (I set the entire background to Alpha), and it surrounds the text. I created the ring using a script to transform a letter 'O' into a 'glassy' style object, which I then resized into an oval of the correct size and shape using the 'scale layer' tool.

The logo looks OK, but would be much improved if I could make the surrounding ring thinner. The ring has a 'glassy' effect which is just what I want, but it is a little on the chunky side. It would look much better if I could transform it to be about half the thickness that it currently is, to match the slimmer text inside the ring. I would like to do this without losing the 'glassy' effect of the ring.

I have already tried creating the ring with the thinnest font I could find that gave me the right shape, but this doesn't go quite far enough. Is there any way that I can thin the ring so that it keeps it's size, position and 'glassy' effect, but ends up with a thickness of about 50% of it's current width? Effectively, I just want to transform a fat ring into a skinny ring!

I have searched for a related tutorial with no luck so far - if anybody knows of a tool or tutorial that could help me with this, then that would be much appreciated!

Instead of using fonts to create your initial ring, use paths. To make a perfect ellipse (and other shapes) use the shape-path plugin (http://registry.gimp.org/node/59).
To make an elliptic ring, create two ellipse paths (same center, but different radiuses) then merge the paths together ("Merge visible paths" in the paths list right click menu). In the same menu, you'll find "Path to selection" to create a selection (on the ring in your case) that you can keep as is or bucket-fill (depending on what your procedure needs).
