LBitmap::MotionBlur
#include "ltwrappr.h"
virtual L_INT LBitmap::MotionBlur (uDim, nAngle, bUnidirectional)
L_UINT uDim; |
/* size of the blur effect */ |
L_INT nAngle; |
/* direction of the motion */ |
L_BOOL bUnidirectional; |
/* flag */ |
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. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
