Compound Blur
Blurs an object using the specified channel of a designated map image. You can use any shape,
text object, still image, or movie file as the map image. You can select any red, green, blue, alpha,
or luminance channel to create the shape of the blur.
Tip: Use this filter to blur specific sections of an image. For example: trace the subject of the
image to blur with a Bezier or B-spline shape, then assign this shape as the Blur Map image. Use
its Luminance or Alpha channel to define the blurred area, then turn off the original shape object
in the Layers list or Timeline to hide the source of the blur. For more information, see
Edit shape
fill, outline, and feathering on page 837.
