LBitmap::MotionBlur (original) (raw)
Summary
Applies a filter, to the class object's bitmap, which creates the illusion of movement in an image.
Syntax
#include "ltwrappr.h"
virtual L_INT LBitmap::MotionBlur (uDim, nAngle, bUnidirectional, uFlags = 0)
Parameters
L_UINT uDim
Size of the blur effect, in pixels.
L_INT 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.
L_BOOL 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. |
L_UINT32 uFlags
Reserved for future use. Must be 0.
Returns
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
