ImageGear21.Processing.Advanced Assembly > ImageGear.Processing Namespace > ImGearEffects Class : DirectionalWave Method

page: Page class object.

angle: Wave angle, in radians.

amplitude: Wave amplitude. Measurement units - pixel / 100.

frequency: Wave frequency. The frequency is defined as 1 / T, where T is a wave period in pixels.

phase: Wave phase, in radians.

attenuation: Wave attenuation. The attenuation factor of the wave is calculated as exp(-attenuation * r), where r is a distance from the wave center to the current wave point.

interpolate: If this parameter is true then an interpolation is used during processing.

color: ImageGear.Core.ImGearPixel class color.

Provides a directional wave effect on the current raster page.
