ImageGear Professional v18.2 > API Reference Guide > Core Component API Reference > Core Component Functions Reference > FX Functions > IG_FX_radial_wave

This function provides a radial wave effect on the hIGear image.

Declaration:

 
Copy Code 
AT_ERRCOUNT ACCUAPI IG_FX_radial_wave(
        HIGEAR hIGear, 
        AT_POINT nCenter,
        AT_FLOAT fAmplitude,
        AT_FLOAT fFrequency,
        AT_FLOAT fPhase, 
        AT_FLOAT fAttenuation, 
        AT_BOOL bInterpolate,
        HIGPIXEL hbkColor, 
        LPAT_RECT lpRect 
);

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.

Supported Raster Image Formats:

When bInterpolate is FALSE, all pixel formats supported by ImageGear Professional, except:

When bInterpolate is TRUE, all pixel formats supported by ImageGear Professional, except:
