Struct Contour 

pub struct Contour {
    pub points: Vec<[f64; 2]>,
    pub closed: bool,
    pub signed_area_m2: Option<f64>,
    pub centroid_m: Option<[f64; 2]>,
}

One contour.

Fields

points: Vec<[f64; 2]>

Vertices [x, y], m. For a closed contour the first vertex is not repeated at the end.

closed: bool

True if the contour closes on itself inside the grid.

signed_area_m2: Option<f64>

Signed shoelace area, m² (positive counter-clockwise, i.e. an outer boundary); None for an open contour.

centroid_m: Option<[f64; 2]>

Area centroid [x, y], m; None for an open contour or one of zero area.

Implementations

impl Contour

pub fn csv(contours: &[Contour]) -> String

CSV of a list of contours: contour,closed,signed_area_m2,centroid_x_m, centroid_y_m,x_m,y_m, one row per vertex (area and centroid on every row of the contour, empty for an open one).
