Blur Modifier

The Blur modifier applies a Gaussian blur to a layer.

Overview

Use the Blur modifier to apply a Gaussian blur effect to the rendering of a layer. There are two parameters that you can adjust: Radius and Opaque.

Radius - Adjust the radial size of the blur. A blur is more diffuse when its radius is large.
Opaque - This property is a Boolean value that indicates whether the blur renderer permits transparency in the blur output. Set to True to create an opaque blur, or set to False to permit transparency.

In this example, there are two Text layers—the first with no blur effect, and the second with the Blur modifier applied with a Radius of 2.
