Poke
This filter distorts an image by bowing the top, bottom, and sides inward, and appears
to push the object into the Canvas at the specified Center point. As the value of the
Amount parameter increases, the more the sides bow in. The
Black Hole filter has a similar
effect but also removes part of the image at the center point.
This filter causes rasterization in 3D groups.
