mode of the contour retrieval algorithm

Variants

RETR_EXTERNAL = 0

retrieves only the extreme outer contours. It sets hierarchy[i][2]=hierarchy[i][3]=-1 for all the contours.

RETR_LIST = 1

retrieves all of the contours without establishing any hierarchical relationships.

RETR_CCOMP = 2

retrieves all of the contours and organizes them into a two-level hierarchy. At the top level, there are external boundaries of the components. At the second level, there are boundaries of the holes. If there is another contour inside a hole of a connected component, it is still put at the top level.

RETR_TREE = 3

retrieves all of the contours and reconstructs a full hierarchy of nested contours.

RETR_FLOODFILL = 4

Trait Implementations

impl Clone for RetrievalModes

fn clone(&self) -> RetrievalModes

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RetrievalModes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<RetrievalModes> for i32

fn from(v: RetrievalModes) -> Self

Converts to this type from the input type.

impl PartialEq for RetrievalModes

fn eq(&self, other: &RetrievalModes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for RetrievalModes

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for RetrievalModes

impl Eq for RetrievalModes

impl StructuralPartialEq for RetrievalModes
