LBitmap::RadialBlur

#include "ltwrappr.h"

virtual L_INT LBitmap::RadialBlur (uDim, uStress, CenterPt)

L_UINT uDim;	/* effect size */
L_UINT uStress;	/* effect intensity */
POINT CenterPt;	/* effect center */

Blurs the image by rotating the pixels around the specified center point. This function is available in the Raster Pro and above toolkits.

Parameter	Description
uDim	An integer that represents the size of the neighborhood used in blurring. Increasing this value will increase the amount of blurring. Valid values range from 1 through 100.
uStress	An integer that represents the amount of the blur intensity. Valid values range from 1 through 100.
CenterPt	POINT structure that contains the point around which the pixels are rotated.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The function will blur the image in a radial form around the specified CenterPt. The center point must be defined inside the bitmap or inside the region, if the bitmap has a region.

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

This function 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 function 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 function.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
