7. The Menus / 7.7 The Menu Filter

7.7.35 Stylize/Vertical Edge, Stylize/Horizontal Edge

These filters are searching for the vertical/horizontal edges in an image. Therefore the result is somewhat similar to the outline filter, but they enhance more the vertical/horizontal structures.

The result is an image, where every found edge is shown a colored line. You can use this filter to convert an image into a line drawing or as special effect.
