Feathering

Sometimes you want to blur the edges of an object so it blends, or fades, into a background object. This is called "feathering". An example is merging two photos together when you want to avoid a sharp edge between them.

The feather control is on the right side of the top bar.

To feather an object:

Select the object or objects you want to feather.
Either enter a numeric size for the feather into the text box OR
Click the arrow to show the pop-up slider. As you drag the slider the objects are feathered.

Feathering blends or blurs the edges of objects.

If you have multiple objects selected, the feather appears around each object. If you group the objects, the feather appears around the outside of the group.

You can also change the feathering profile. Normally a linear transition across the feather produces the best effect, but you may want to change this.

Select the Profile button to display the Profile dialog and adjust the sliders.
