Let lay I have a ring shape (a cricle where I substracted a smaller circle from it.

Is it possible to apply a blur effect to the ring that would only blur the interior part of the ring rather than the interior and exterior of the ring.

With the following filters you don't need to substract one circle to another ; only grouping them together is needed.

Do like in the joined file "Blur inside" :

- Create a filled circle ;
- draw a smaller circle on top of it and blur only this one ;
- group them ;
- apply the filter Transparency utilities/Light eraser to this group

Or do like in the second file "Blur inside-b" :

If you need to do that to a white or very light circle, fill the wide circle with black and the small one with white and after processing like above, do Ctrl+G again, apply the filter Transparency utilities/Alpha repaint monochrome to this group, open the Filters Editor, click on the name of this last filter and change this filters Flood color to white or any other color you need.
