   int amplitude, 
   int frequency, 
   int phase, 
   int zoomFactor, 
   Leadtools.LeadPoint centerPoint, 
   Leadtools.RasterColor fillColor,

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.

Example

Run the ZoomWaveCommand on an image.
