Dark Strokes

The Dark Strokes effect paints the image with diagonal black-and-white brush strokes. Light areas become white and are painted with long strokes that extend into non-white areas. Dark areas become black and are painted with short, tight strokes.

Name	Specifies the operator's name.
Opacity	Sets the opacity of the effect over the input image. A value of 0 makes the effect completely transparent, while a value of 100 makes it completely opaque.
Use Alpha As Mask	Uses the input image's alpha channel as a mask for applying the effect. The effect is fully applied to areas of the image where the alpha channel is white, and not at all to areas where it is black.
Run Effect On	Enable the RGB and/or Alpha options to specify whether the effect is applied to the RGB channels, the Alpha channel, or both.
Balance	The Balance slider changes the proportions of the areas affected by each of the two painting strokes.
Black Intensity	Set lower values to decrease the intensity of the black painted on the image, or set higher values to increase the intensity.
White Intensity	Set lower values to decrease the intensity of the white painted in the image, or set higher values to increase the intensity.
