Arguments:
| Name | Type | Description |
| hIGear | HIGEAR | Image to which to apply the effect. |
| nCenter | AT_POINT | Center of the wave effect, in pixels. |
| fAmplitude | AT_FLOAT | Wave amplitude. Measurement units - pixel / 100. |
| fFrequency | AT_FLOAT | The frequency is defined as 1 / T, where T is a wave period, in pixels. |
| fPhase | AT_FLOAT | Wave phase, in radians. |
| fAttenuation | AT_FLOAT | 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. |
| bInterpolate | AT_BOOL | If TRUE, interpolation is used during processing. |
| hbkColor | HIGPIXEL | Background color. It should have the same color space and channel depths as the image to which the effect is applied. |
| lpRect | LPAT_RECT | Rectangular area to apply the effect to, or NULL for whole image. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call.
