Chapter 20. Using Filters and Effects > About Filters and Effects

About Filters and Effects

Filters and effects, in most cases, are simply shortcuts. They do automatically, or with the drag of a slider and the click of a button, what could take hours to do manually. There are some filters and effects that would be almost impossible to replicate step by step in Illustrator. Illustrator installs, by default, nearly 140 filters and effects.

What They Do and How They Do It

Most of the filters and effects in Illustrator work in one of two ways. They either manipulate the appearance of an object by changing the way its path looks, or they alter the appearance by rasterizing and manipulating pixels. (Some do both, and so fall outside these general statements.) The difference can be categorized as similar to the difference between vector and raster artwork. One works with paths, one works with pixels. (And one set of effects is for use strictly with scalable vector graphics files.)
