| esriOutlineVectorization | 1 | Vectorize the outlines. | 
Centerline:
When this method is selected, raster features with a width less that the Maximum Line Width (see Vectorization Settings) will be vectorized as lines following the center of the raster feature. Raster features with a width greater than the Maximum Line Width will be vectorized as polygons enclosing the raster features.
