Linear Blur

This effect acts only in one direction which can vary up to an angle of 180$\degree$ with these parameters:

Figure 10.50: For clarity of presentation only 2 fields are shown
Image linear

Length:
distance between original image and final blur step; corresponds to the distance of the fields.
Angle:
angle of motion in one direction for linear blur
Steps:
number of blur steps to be used in the calculation. Increasing the number takes more CPU.
Channels:
R,G,B,A.
Clear
With the Clear buttons we can bring the slider to default values without affecting the other parameters.

Figure 10.50 shown here has the parameters: Length = 19, Angle = 25, and Steps = 2.
