This sub-menu contains effects that can produce stylized looks useful in finding edges for tracing, or producing specialized textures for game development (e.g., bump maps).
The following original image will be used for examples:
This effect will highlight the edges in an image as if a light had been shown on it from a certain angle.
This effect will result in a black and white image where the edges have been given a three-dimensional highlight similar to physical embossing.
This effect will find the edges of an image and trace around them with the requested radius.
This effect is similar to Edge Detect, except that it blends the result back into the original image.
