Curves and shadows
Hello, I am trying to Drop Shadow (Filters > Light and Shadow > Drop Shadow) on a shape with curved corners. Results are great when using Drop Shadow on shapes with no curved corners, but on shapes with curved corners, the end result is very pixilated (see attached). I tried using Gaussian Blur but I do not like the result.

Are there any tips and tricks of how to drop shadow on curved shapes?

As always a big thanks for your reply. Attached is my .xcf file. I arrived to this result using the following steps:

1. Create a new image (transparent background).
2. Use Rectangle Select Tool with rounded corners.
3. Draw a shape and painted white.
4. Create a new layer and paint this grey.
5. Select the shape with rounded corners (using magic wand).
6. Go to Filters > Light and Shadow > Drop Shadow ...
7. Set: Offset-X = 0, Offset-Y = 0, Blur Radius = 10, Allow Resizing = false
8. I get a shadow but corners look pixilated Sad

The above steps are find for a squared shape, but as you can see from the result, a rounded shape does not look that great.

I use the selection tool to select an area on the transparent layer, then I fill that selection.

"Layer/Transparency/Alpha to selection" gives me better results (see attached). What does this option do? Is it possible to get better results then that?
