Initializes a new FreeHandWaveCommand class object with explicit parameters.
Syntax
Parameters
- amplitudes
- Array of integers that represent wave values. The real value of the array elements is divided by 1000. These values are generally obtained from the GetCurvePoints utility method.
- scale
- Factor used to increase or decrease the various amplitude values in the amplitudes array. Each value in the amplitudes array is multiplied by this factor. The real factor value is the Scale value divided by 100. This property only accepts positive values.
- waveLength
- Value that represents the wave length, if FreeHandWaveCommandFlags.Period flag is set. Possible values range from 1 - 100 and give the wavelength as a percentage of the image dimensions. If FreeHandWaveCommandFlags.Frequency flag is set, this value is the number of repeated waves.
- angle
- Wave rotation angle in hundredths of a degree (+/-). The valid range is from -36000 to 36000. The value in degrees is angle divided by 100.
- fillColor
- RasterColor object that specifies the fill color for any exposed areas.
- flags
- FreeHandWaveCommandFlags enumeration that indicate how to handle exposed areas, and the type of information contained in waveLength parameter.
Example
Run the FreeHandWaveCommand on an image and apply triangular wave on the loaded image.
