LBitmap::MotionBlur

#include "ltwrappr.h"

virtual L_INT LBitmap::MotionBlur (uDim, nAngle, bUnidirectional, uFlags = 0)

L_UINT uDim;	size of the blur effect
L_INT nAngle;	direction of the motion
L_BOOL bUnidirectional;	flag
L_UINT32 uFlags;	flags

Applies a filter, to the class object's bitmap, which creates the illusion of movement in an image.

Parameter	Description
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.
uFlags	Reserved for future use. Must be 0.

Returns

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