Channel Blur
Gives you control over blurring each color channel of an object. The Channel blur can be applied
selectively to each color channel of an object: red, green, blue, and alpha. Blurring individual
channels lets you create customized glow effects by retaining sharpness in selected channels
while softening others.

Circle Blur
Creates a circular blur within an image, specified by a center point that sets the center of the blur
effect and a radius that sets the size of the affected region. The amount of blur in the affected
area can also be customized.
This filter is useful for blurring a limited area in an image. For more sophisticated control of the
image region to be blurred, use the Compound Blur filter.
This filter causes rasterization in 3D groups. For more information on rasterization, see Groups
and rasterization on page 1045.
