public: ZoomWaveCommand( int amplitude, int frequency, int phase, int zoomFactor, LeadPoint centerPoint, RasterColor fillColor, ZoomWaveCommandType type ) |
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 Leadtools.ImageProcessing.SpecialEffects.ZoomWaveCommand on an image.
