LBitmap::ZoomBlur

#include "ltwrappr.h"

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

L_UINT uDim;	/* amount of blur */
L_UINT uStress;	/* blur intensity */
POINT CenterPt;	/* center point */
L_UINT32 uFlags;	/* flags*/

Blurs the image along radial lines starting from the specified center point.

Parameter	Description
uDim	A value that represents the amount of the blur.
uStress	A value that represents the amount of the blur intensity.
CenterPt	POINT structure that contains the center point from which to blur the image.
uFlags	Reserved for future use. Must be 0.

Returns

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

Comments

The function will blur and zoom the image 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.
