Contour Drawing
This effect transforms a true-color image into an illustration drawing by outlining
the detected edges in the image into simple brush strokes.
Note: The best settings for this effect are greatly dependent on the image you are
working with. This effect works particularly well with images containing higher
contrast and bold shapes.
To apply the Contour Drawing effect:
1. Select Effect: Artistic - Contour Drawing.
2. For an image showing a lot of detail (especially on the subject's background),
set Edge sensitivity to Low to avoid picking up too much unwanted detail.
If the subject from which contours will be drawn has a plain background, you
can choose a Moderate or High sensitivity level.
Original image
3. Set the amount of detail to be traced and drawn with contours by adjusting the
Threshold range slider.
First, try to set a wide range to have more contours drawn. If this results in too
much unwanted background noise, drag the left clipping tab of the slider to the
left until the background noise is removed.
