Parameters

amplitude: Zoom wave magnitude.
frequency: The number of repeated waves along the radial line. This parameter only accepts positive values.
phase: Wave phase shift. The valid range is from -36000 to 36000. The real value is divided by 100.
zoomFactor: The percentage the wave grows as it moves from the image center. The valid range is from 0 to 100.
centerPoint: Center point from which the wave is zoomed.
fillColor: RasterColor object that specifies the fill color for any exposed areas.
type: Flag that indicates how to handle exposed areas.

Run the ZoomWaveCommand on an image.
