In computer graphics, a feature of many drawing programs in which a bitmapped graphic is converted to a vector graphic. A bit map is imported into the illustration program as a template, and a path is traced around the detectable edges of the image. It is then translated into Bézier curves characteristic of vectors. Depending on the complexity of the bit map, autotrace features have varying degrees of utility. See Bit Map and Vector. Also spelled as two words, auto trace.
