L_MotionBlurBitmap

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_MotionBlurBitmap(pBitmap, uDim, nAngle, bUnidirectional)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uDim;	/* size of the blur effect */
L_INT nAngle;	/* direction of the motion */
L_BOOL bUnidirectional;	/* flag */

Applies a filter, which creates the illusion of movement in an image.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap to blur.
uDim	Size of the blur effect, in pixels.
nAngle	Value that represents the direction of the motion, in hundredths of a degree (+/-) This value can be a number from 0 to 36000. If the value is positive, the motion will be clockwise. If the value is negative, the motion is counter-clockwise.
bUnidirectional	Flag that indicates whether the motion extends only in one direction. Possible values are:
	Value	Meaning
	TRUE	The motion blur effect is only in the direction specified in nAngle.
	FALSE	The motion blur effect is along the line with that angle. For example, if nAngle is 0, the blur effect will occur in the 0 degree direction and the 180 degree direction.

Returns

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

Comments

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.

Example

/* This example loads a bitmap and creates motion blur. */
BITMAPHANDLE LeadBitmap; /* Bitmap handle to hold the loaded image. */
/* Load the bitmap, keeping the bits per pixel of the file */
L_LoadBitmap (TEXT("IMAGE1.CMP"), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
/* blur the bitmap */
L_MotionBlurBitmap(&LeadBitmap,20,4500,FALSE);
