Gaussian Blur

Settings

The following settings are shown on the Effects panel:

• Radius—controls the extent of the effect.
• Preserve Alpha—when checked, object edges are not subject to blurring.

The following advanced settings can be adjusted in the Layer Effects dialog:

• Scale with Object—when selected, the effect scales in proportion to the object if the object is resized. If this option is off, the effect's scale remains unchanged when the object is resized.
• Fill Opacity—sets the opacity of the layer contents without affecting the applied effects.
