INPUT CLIP
Clip to blur.
Length (Min: 0.0 Max: 100.0 Default: 5.0)
Controls the distance over which the 'camera moves'.
Angle (Default: 0.0)
Controls the angle at which the camera moves, in degrees.
Zero degrees is due east.
Center (Default: On)
On=1: makes the motion of the camera appear to be from half the Size on one side of
the image center to half the Size on the other side of the center.
Off=0: the camera will appear to have moved from the image center in the selected
direction.
PRINCIPLE OF OPERATION Using the angle and size parameters, a line can be drawn from each pixel on the input image. The pixels under the line are 'averaged' to find the color of the corresponding output pixel. Anti-aliasing based on exact polygon clipping is actually used. Speed of operation is dependent on the length of the lines - i.e. on the Length control setting.
