Channel Blur
Gives you control over blurring each color channel of an object. The Channel blur can
be applied selectively to each of the different color channels of the object: red, green,
blue, and alpha.
Blurring individual channels allows you to create customized glow effects by retaining
sharpness in selected channels while softening others.
Parameters in the Inspector
Amount: Sets the radius of the object blur. Values range from 0 (no blur) to 32.
Blur Red: Sets the blur to affect the red channel. Can be turned On or Off.
Blur Green: Sets the blur to affect the green channel. On or Off.
Blur Blue: Sets the blur to affect the blue channel. On or Off.
Blur Alpha: Sets the blur to affect the alpha channel. On or Off.
Horizontal: Sets the percentage of maximum horizontal blur. This is a percentage of
the Amount parameter.
Vertical: Sets the percentage of maximum vertical blur.
Crop: Toggles whether or not the image is cropped beyond its original borders.
Dashboard controls

Circle Blur
Creates a circular blur within an image, specified by a center point which sets the
center of the blur effect, and a radius which sets the size of the affected region. The
amount of blur within the affected area can also be customized.
