DiffuseGlow method (ILEADRasterProcess)

Syntax	short DiffuseGlow(ILEADRaster * pRaster, long lGlowAmount, long lClearAmount, long lSpreadAmount, long lWhiteNoise, OLE_COLOR crGlowColor);
Overview	Refer to Applying Artistic Effects.

Remarks

(Raster Pro and above only) Adds a colored glow to a bitmap's light or dark areas, making these areas shine with a neon glow.

This filter adds pixels randomly to the bitmap. A glow is added based on a combination of the pixel colors and the glow color.

As an example, if you use the following image:

$image\diffuseglowbefore.gif$

And you were to call DiffuseGlow using the following settings:

Parameter	Value
lGlowAmount	50
lClearAmount	50
lSpreadAmount	10
lWhiteNoise	10
crGlowColor	white

The following figure results:

$image\diffuseglow.gif$

If the bitmap has a region, the effect will be applied on the region only.

This method supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.

This method does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
