L_ZoomBlurBitmap

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_ZoomBlurBitmap (pBitmap, uDim, uStress, CenterPt)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uDim;	/* amount of blur */
L_UINT uStress;	/* blur intensity */
POINT CenterPt;	/* center point */

Blurs the image along radial lines starting from the specified center point. This function is available in the Raster Pro and above toolkits.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap on which to apply the effect.
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.

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.

To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.

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.

Example

BITMAPHANDLE LeadBitmap;   /* Bitmap handle for the image */
POINT CenterPt;

/* Load a bitmap at its own bits per pixel  */
L_LoadBitmap(TEXT("IMAGE3.CMP"), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);

/* Zoom blur*/
CenterPt.x  =  LeadBitmap.Width/2;
CenterPt.y  =  LeadBitmap.Height/2;
L_ZoomBlurBitmap (&LeadBitmap, 50, 5, CenterPt);
