Motion Blur

motion

This effect creates the illusion of movement in an image.

Motion Blur settings:

motion options
Motion in one direction only: If this is checked, the motion is in only one direction and at the angle specified by the Angle slider. If this is not checked, then the motion is along a line using the angle specified by the Angle slider. For example, if the Angle slider is 0, the motion blur will be in the 0 direction and in the 180 direction.

Blur size: Size of the blur effect in pixels. Range: 1 – 100

Angle: Direction of the motion in degrees. Range: 0 – 360


Radial Blur

radial

This effect blurs the image by rotating the pixels around the specified center point.

Radial Blur settings:

radial options
Blur size: This value is the size of the neighborhood used to blur. Range: 1 – 100

Intensity: This value is the amount of the blur intensity. Range: 1 – 100

Center x and Center y: This is the point around which the pixels are rotated to create the blur. Range: 0 – to width and/or height of image


Zoom Blur

zoom

This effect blurs the image along radial lines starting from the specified center point.

Zoom Blur settings:

zoom options
Blur size: This value is the size of the blur. Range: 1 – 100

Intensity: This value is the amount of the blur intensity. Range: 1 – 100

Center x and Center y: This is the point from which to blur the image. Range: 0 – to width and/or height of image


Gaussian Blur

gausian

This effect reduces detail and noise in the image. The Gaussian function, named after Carl Friedrich Gauss, creates a smooth even blur like looking at the image through a translucent screen.

Gaussian Blur settings:

gausian options
Radius: This value gives the radius of the neighborhood to apply the blur. Range: 1 – 100


Antialias Blur

antialias

This effect blends pixel colors along edges to avoid a jagged look.

Antialias Blur settings:

antialias options
Antialias filters: Select from 6 different options for applying the effect: Vertically and horizontally, In all directions, In all directions, different from 2, Diagonally, Horizontally and Vertically.

Threshold: The threshold value indicates which pixels to smooth. Only pixels with values above this threshold are smoothed. The smaller the value, the more antialias blur applied. Range: 0 – 100

Blur size: This value is the size of the blur. Range: 1 – 50


Average Blur

average

This effect changes the color of each pixel in the image to the average color of pixels in its neighborhood. This results in a blur effect.

Average Blur settings:

average options
Blur size: The length of one side of a square that is the neighborhood for averaging. Range: 1 – 100
