Blur Filter Effect
Description
Averages the pixels of the visible object for a specified length and direction, creating the impression that the object is moving at high speed.
Syntax
{FILTER: Blur(Add=add, Direction=direction, Strength=strength)}
Parameter Description add Boolean switch specifying whether to add the original image to the motion-blurred image. If true (nonzero integer), the image is added to the motion blurred image; if false (zero), the image is not added to the motion blurred image. direction Direction of the motion blur clockwise from the vertical orientation of the object, rounded to 45-degree increments. The default value is 0 (straight up). Possible values are shown in the following table.
Value Description 0 Top 45 Top right 90 Right 135 Bottom right 180 Bottom 225 Bottom left 270 Left 315 Top left strength Long value that specifies the number of pixels the blur will extend. Remarks
You can create a nice effect for fonts by setting add to 1.
For the direction parameter, negative values or values larger than 360 degrees will wrap around to their equivalent angle (for example, -45 degrees is equivalent to 315-degree orientation). This allows mathematical manipulations to be carried out easily in code.
