The Bulge effect distorts an image around a specified point, making the image appear to bulge toward or away from the viewer, depending on the options you select.

This effect works with 8-bpc and 16-bpc color.

Horizontal Radius and Vertical Radius

The width and height of the distorted area, in pixels. You can also set the radius values by dragging the selection handles in the layer.

Bulge Height

The apparent depth of the bulge. Positive values push the bulge toward the viewer. Negative values pull the bulge away from the viewer.

Taper Radius

The shallowness of the sides of the bulge. A taper radius of 0 produces a steep, pronounced bulge.

Antialiasing

The amount of edge smoothing (blending of colors) at the boundaries of the bulge. Anti-aliasing is applied only when the layer quality is set to Best.

Pin All Edges

Prevents the edges of the layer from bulging.
