Line Art
Performs an edge detection of the high-contrast borders between regions of differing
brightness in an object, tracing the edges and reducing other detail in the image to the
color specified by the Paper Color parameter. The color of the resulting outline can also
be customized. The effect is that of a line drawing on paper.
