Bulge and Shrink options

Horizontal position

Specifies the center of the distortion along the horizontal axis. A lower value moves the distortion towards the left side of the image, while a higher value moves it towards the right side of the image.

Vertical position

Specifies the center of the distortion along the vertical axis. A lower value moves the distortion towards the bottom of the image, while a higher value moves it towards the top of the image.

Radius

Specifies the radius of the distorted area. A lower value decreases the radius of the distortion, while a higher value increases the radius of the distortion.

Strength

Specifies the strength of the distortion. A negative value shrinks the center of the distortion, while a higher value bulges the distortion.

Background color

Specifies the background color for the filtered image.

Select the Image check box to use the original image color, or click the color picker to select a different color.

Bulge direction

Specifies the direction of the distortion. Select one or both of the following options:

  • Horizontal: Moves the distortion horizontally.
