Transform an image or the selected area into a pencil-sketch.

This method can be very slow for large images or for particular combination of parameters (like levelSteps and antialiasedLines).

It also requires a lot of memory and can fail processing large images.

Parameters

grayScale: Boolean
If True produces gray scale drawings.

levelSteps: Int32
Determines number of colors detected from the image. Suggested range: 2 up to 6.

maxTextures: Int32
Overcome LevelSteps parameter, specifing maximum number of textures (colors) to generate.

edgeBlurAmount: Int32
Specifies the edge thickness. Suggested range: 2 up to 10.

edgeAmount: Double
Specifies the edge amount. Suggested range: 0 up to 2.

lineThickness: Double
Specifies drawn lines thickness. Suggested range: 0.5 up to 10.

darkeningFactor: Double

lineAlpha: Double
Specifies drawn lines transparency (alpha). Suggested range: 0.05 up to 0.5.

lineDensity: Double
Specifies drawn lines density (how much lines are drawn in the textures). Suggested range: 0.25 up to 1.

lightness: Double
Specifies the overall lightness of the resulting image. Suggested range: 1 up to 8.

antialiasedLines: Boolean
If True texture lines are drawn with antialiasing routine.
