Struct Text

pub struct Text { /* private fields */ }

• This structure represents a text string to draw.
• Parameters match cv::putText().

Implementations

impl Text

pub fn new( text_: &str, org_: Point, ff_: i32, fs_: f64, color_: Scalar, thick_: i32, lt_: i32, bottom_left_origin_: bool, ) -> Result<Text>

Text constructor

Parameters

• text_: The text string to be drawn
• org_: The bottom-left corner of the text string in the image
• ff_: The font type, see [hershey_fonts]
• fs_: The font scale factor that is multiplied by the font-specific base size
• color_: The text color
• thick_: The thickness of the lines used to draw a text
• lt_: The line type. See [line_types]
• bottom_left_origin_: When true, the image data origin is at the bottom-left corner. Otherwise, it is at the top-left corner

C++ default parameters

• thick_: 1
• lt_: 8
• bottom_left_origin_: false

pub fn new_def( text_: &str, org_: Point, ff_: i32, fs_: f64, color_: Scalar, ) -> Result<Text>

Text constructor

Parameters

• text_: The text string to be drawn
• org_: The bottom-left corner of the text string in the image
• ff_: The font type, see [hershey_fonts]
• fs_: The font scale factor that is multiplied by the font-specific base size
• color_: The text color
• thick_: The thickness of the lines used to draw a text
• lt_: The line type. See [line_types]
• bottom_left_origin_: When true, the image data origin is at the bottom-left corner. Otherwise, it is at the top-left corner

Note

This alternative version of [new] function uses the following default values for its arguments:

• thick_: 1
• lt_: 8
• bottom_left_origin_: false

Trait Implementations

impl Boxed for Text

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

Wrap the specified raw pointer

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

Return the underlying raw pointer while consuming this wrapper.

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

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer

impl Clone for Text

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Text

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