Declarationprocedure PencilSketch(GrayScale: boolean = true; LevelSteps: integer = 2; MaxTextures: integer = MAXINT; EdgeBlurAmount: integer = 4; EdgeAmount: double = 0.5; LineThickness: double = 1; DarkeningFactor: double = 0.1; LineAlpha: double = 0.1; LineDensity: double = 0.5; Lightness: double = 4; AntialiasedLines: boolean = false);
Transform an image or 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.
|Parameter ||Description |
| GrayScale || If True, output will be gray scale |
| LevelSteps || Number of colors to detect in image. Suggested range: 2 to 6 |
| MaxTextures || Overcome LevelSteps parameter, specifying the maximum number of textures (colors) to generate |
| EdgeBlurAmount || Thickness of edges. Suggested range: 2 to 10 |
| EdgeAmount || The edge amount. Suggested range: 0 to 2 |
| LineThickness || Thickness of drawn lines. Suggested range: 0.5 to 10 |
| DarkeningFactor || Darkness of output image. Suggested range: 0 to 10 |
| LineAlpha || Transparency (alpha) of drawn lines. Suggested range: 0.05 to 0.5 |
| LineDensity || Density of drawn lines (how many lines are drawn in the textures). Suggested range: 0.25 to 1 |
| Lightness || Overall lightness of the output image. Suggested range: 1 to 8 |
| AntialiasedLines || If True, texture lines are drawn with antialiasing routine |
