Struct opencv::imgproc::Subdiv2D

pub struct Subdiv2D { /* fields omitted */ }

Methods

impl Subdiv2D

pub fn as_raw_Subdiv2D(&self) -> *mut c_void

pub unsafe fn from_raw_ptr(ptr: *mut c_void) -> Self

impl Subdiv2D

pub fn default() -> Result<Subdiv2D>

creates an empty Subdiv2D object. To create a new empty Delaunay subdivision you need to use the #initDelaunay function.

pub fn new(rect: Rect) -> Result<Subdiv2D>

creates an empty Subdiv2D object. To create a new empty Delaunay subdivision you need to use the #initDelaunay function.

Overloaded parameters

Parameters

• rect: Rectangle that includes all of the 2D points that are to be added to the subdivision.

The function creates an empty Delaunay subdivision where 2D points can be added using the function insert() . All of the points to be added must be within the specified rectangle, otherwise a runtime error is raised.
