LBitmap::RadialBlur

Summary

Blurs the image by rotating the pixels around the specified center point.

Syntax

#include "ltwrappr.h"

virtual L_INT LBitmap::RadialBlur (uDim, uStress, CenterPt, uFlags = 0)

Parameters

L_UINT 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.

L_UINT uStress

An integer that represents the amount of the blur intensity. Valid values range from 1 through 100.

POINT CenterPt

POINT structure that contains the point around which the pixels are rotated.

L_UINT32 uFlags

Reserved for future use. Must be 0.

Returns

Value	Meaning
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.
