Trait Implementations

impl AlgorithmTrait for FreeType2

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 FreeType2

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 FreeType2

unsafe fn from_raw(ptr: <FreeType2 as OpenCVFromExtern>::ExternReceive) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> <FreeType2 as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> <FreeType2 as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut( &mut self, ) -> <FreeType2 as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying mutable raw pointer

impl Debug for FreeType2

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

Formats the value using the given formatter.

impl Drop for FreeType2

fn drop(&mut self)

Executes the destructor for this type.

impl FreeType2Trait for FreeType2

fn as_raw_mut_FreeType2(&mut self) -> *mut c_void

fn load_font_data(&mut self, font_file_name: &str, idx: i32) -> Result<()>

Load font data.

unsafe fn load_font_data_1( &mut self, p_buf: *mut c_char, buf_size: size_t, idx: i32, ) -> Result<()>

Load font data.

fn set_split_number(&mut self, num: i32) -> Result<()>

Set Split Number from Bezier-curve to line

fn put_text( &mut self, img: &mut impl ToInputOutputArray, text: &str, org: Point, font_height: i32, color: Scalar, thickness: i32, line_type: i32, bottom_left_origin: bool, ) -> Result<()>

Draws a text string.

fn get_text_size( &mut self, text: &str, font_height: i32, thickness: i32, base_line: &mut i32, ) -> Result<Size>

Calculates the width and height of a text string.

impl FreeType2TraitConst for FreeType2

fn as_raw_FreeType2(&self) -> *const c_void

impl From<FreeType2> for Algorithm

fn from(s: FreeType2) -> Self

Converts to this type from the input type.

impl Send for FreeType2
