A filter pack to help indicating the luminosity levels of objects, to help out manual tracing -possible use for creating gradient meshes over a photograph, it makes mesh node placement easier.



A convolve matrix filter primitive is used to draw a 1 px wide line around the same tone levels of the source.

Colour of the contours can be set by the flood fill at the start of the filter link.
