uDim |
Size of the blur effect, in pixels. Possible values range from 3 - 100. |
|
nAngle |
Value that represents the direction of the motion, in hundredths of a degree (+/-). Possible values range from -36000 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. |
