pub struct Contour<T> {
    pub points: Vec<Point<T>>,
    pub border_type: BorderType,
    pub parent: Option<usize>,
}

Expand description

A border of an 8-connected foreground region.

Fields

points: Vec<Point<T>>

The points in the border.

border_type: BorderType

Whether this is an outer border or a hole border.

parent: Option<usize>

Calls to find_contours and find_contours_with_threshold return a Vec of all borders in an image. This field provides the index for the parent of the current border in that Vec.
