Trait Implementations

impl AlgorithmTrait for FastLineDetector

fn as_raw_mut_Algorithm(&mut self) -> *mut c_void

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn read(&mut self, fn_: &impl FileNodeTraitConst) -> Result<()>

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for FastLineDetector

fn as_raw_Algorithm(&self) -> *const c_void

fn write(&self, fs: &mut impl FileStorageTrait) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut impl FileStorageTrait, name: &str) -> Result<()>

Stores algorithm parameters in a file storage

fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

@deprecated

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of AlgorithmTraitConst::write_with_name function uses the following default values for its arguments:

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

impl Boxed for FastLineDetector

unsafe fn from_raw( ptr: <FastLineDetector as OpenCVFromExtern>::ExternReceive, ) -> Self

Wrap the specified raw pointer

fn into_raw( self, ) -> <FastLineDetector as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> <FastLineDetector as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut( &mut self, ) -> <FastLineDetector as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying mutable raw pointer

impl Debug for FastLineDetector

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

Formats the value using the given formatter.

impl Drop for FastLineDetector

fn drop(&mut self)

Executes the destructor for this type.

impl FastLineDetectorTrait for FastLineDetector

fn as_raw_mut_FastLineDetector(&mut self) -> *mut c_void

fn detect( &mut self, image: &impl ToInputArray, lines: &mut impl ToOutputArray, ) -> Result<()>

@example fld_lines.cpp An example using the FastLineDetector

fn draw_segments( &mut self, image: &mut impl ToInputOutputArray, lines: &impl ToInputArray, draw_arrow: bool, linecolor: Scalar, linethickness: i32, ) -> Result<()>

Draws the line segments on a given image.

fn draw_segments_def( &mut self, image: &mut impl ToInputOutputArray, lines: &impl ToInputArray, ) -> Result<()>

Draws the line segments on a given image.

impl FastLineDetectorTraitConst for FastLineDetector

fn as_raw_FastLineDetector(&self) -> *const c_void

impl From<FastLineDetector> for Algorithm

fn from(s: FastLineDetector) -> Self

Converts to this type from the input type.
