ZoomWaveCommand Constructor(Int32,Int32,Int32,Int32,LeadPoint,RasterColor,ZoomWaveCommandType)

Example 





Zoom wave magnitude.
The number of repeated waves along the radial line. This parameter only accepts positive values.
Wave phase shift. The valid range is from -36000 to 36000. The real value is divided by 100.
The percentage the wave grows as it moves from the image center. The valid range is from 0 to 100.
Center point from which the wave is zoomed.
RasterColor object that specifies the fill color for any exposed areas.
Flag that indicates how to handle exposed areas.
Initializes a new ZoomWaveCommand class object with explicit parameters. .NET support WinRT support
