How To Achieve A Blurry Stroke?
Hi!
My first post here.
I have used Photoshop in the past and am learning the GIMP and I have my first question.
In Photoshop if you make a selection, feather that selection and then apply a stroke to that selection you get a nice, controlible stroke that is blurred into the feather.
In the GIMP when you stroke a feathered selection you just get a hard stroke on the original selecten. The feathering does not effect the stroke.
Is there a way to achieve a blurred stroke like I can in PS? Thanks!

Hmm. Works for me.
- Create 150px radius circular selection
- Feather 100px
- Stroke with hard brush along a radius

Produces this:

Maybe I was not clear.
I was not refering to a brush stroke accross the selection, I was talking about using the Edit/Stroke Selection cammand to achieve a blur following the selection.

Edit/Stroke selection and use the Blur/Convolve tool?

It does look like some experimentation is in order. Smile

I have failed to find an way to achieve what I want and thought an example might help explain what I am aiming at.

RE: How To Achieve A Blurry Stroke?
The selection in Gimp acts like a filter on the affected pixels. It will never widen your stroke. For what you want once you have feathered the selection you have to use a stroke at least as wide at the feathered selection (and it's faster to just bucket-fill).

However, the feathered selection is a gaussian blur and you may find it a bit soft in the middle. You won't get the semi-sharp line as in your PS image, which would require a second stroke with less feathering.

Huh, I will give that a shot and see how it goes. Thanks.
