Zoom In/Out Establishes the direction of the blur effect toward or away from the viewer. Type a number from -100 to 100 or drag the slider to set the value. Negative numbers make the image appear to move closer; positive numbers make the image appear to move away. Smoothness Controls the quality of the transition of the blur effect. Type a number from 1 to 10 or drag the slider to set the value. A smaller number creates a smoother blur with fine color blending. Centering options These options let you set the zoom origin. Cen- ter In Image sets the origin at the center of the image. Center in Selection sets the origin at the center of a selection. “Offset from Center in Pixels” lets you type values to offset the origin from the center of the image or selection.

Positive horizontal offsets move the center to the right. Positive verti- cal offsets move the center down. Preview Displays the effect of the current settings.
