Descripción

This effect/filter detects and draws edges using the Canny edge detection algorithm[1].

Parámetros

Parámetro	Valor	Descripción
Umbral inferior / superior	Decimal	Set low and high threshold values used by the algorithm. The High threshold selects the «strong» edge pixels, which are then connected through 8-connectivity with the «weak» edge pixels selected by the Low threshold. Range is from 0.000 to 1.000 with Low threshold being lower or equal to High threshold.
Modos	Selección	Define the drawing mode
Planos	Selección	Select the planes for filtering

The following selection items are available:
