Struct egui_plotter::EguiBackend

pub struct EguiBackend<'a> { /* private fields */ }

Plotter backend for egui; simply provide a reference to the ui element to use.

Implementations

impl<'a> EguiBackend<'a>

pub fn new(ui: &'a Ui) -> Self

Create a backend given a reference to a Ui.

pub fn set_offset(&mut self, offset: (i32, i32))

Set the offset(x + y) of the backend.

pub fn offset(self, offset: (i32, i32)) -> Self

Set the offset(x + y) of the backend. Consumes self.

pub fn set_scale(&mut self, scale: f32)

Set the scale of the backend.

pub fn scale(self, scale: f32) -> Self

Set the scale of the backend. Consume self.

Trait Implementations

impl<'a> DrawingBackend for EguiBackend<'a>

type ErrorType = Error

The error type reported by the backend

fn get_size(&self) -> (u32, u32)

Get the dimension of the drawing backend in pixels

fn ensure_prepared(&mut self) -> Result<(), DrawingErrorKind<Self::ErrorType>>

Ensure the backend is ready to draw

fn present(&mut self) -> Result<(), DrawingErrorKind<Self::ErrorType>>

Finalize the drawing step and present all the changes. This is used as the real-time rendering support. The backend may implement in the following way, when ensure_prepared is called it checks if it needs a fresh buffer and present is called rendering all the pending changes on the screen.

fn draw_pixel( &mut self, point: (i32, i32), color: BackendColor ) -> Result<(), DrawingErrorKind<Self::ErrorType>>

Draw a pixel on the drawing backend

fn draw_line<S: BackendStyle>( &mut self, from: (i32, i32), to: (i32, i32), style: &S ) -> Result<(), DrawingErrorKind<Self::ErrorType>>

Draw a line on the drawing backend

fn draw_text<TStyle: BackendTextStyle>( &mut self, text: &str, style: &TStyle, pos: (i32, i32) ) -> Result<(), DrawingErrorKind<Self::ErrorType>>

Draw a text on the drawing backend

fn draw_path<S: BackendStyle, I: IntoIterator<Item = BackendCoord>>( &mut self, path: I, style: &S ) -> Result<(), DrawingErrorKind<Self::ErrorType>>

Draw a path on the drawing backend

fn fill_polygon<S: BackendStyle, I: IntoIterator<Item = BackendCoord>>( &mut self, vert: I, style: &S ) -> Result<(), DrawingErrorKind<Self::ErrorType>>

fn draw_rect<S>( &mut self, upper_left: (i32, i32), bottom_right: (i32, i32), style: &S, fill: bool ) -> Result<(), DrawingErrorKind<Self::ErrorType>>where S: BackendStyle,

Draw a rectangle on the drawing backend

fn draw_circle<S>( &mut self, center: (i32, i32), radius: u32, style: &S, fill: bool ) -> Result<(), DrawingErrorKind<Self::ErrorType>>where S: BackendStyle,

Draw a circle on the drawing backend

fn estimate_text_size<TStyle>( &self, text: &str, style: &TStyle ) -> Result<(u32, u32), DrawingErrorKind<Self::ErrorType>>where TStyle: BackendTextStyle,

Estimate the size of the horizontal text if rendered on this backend. This is important because some of the backend may not have font ability. Thus this allows those backend reports proper value rather than ask the font rasterizer for that.

fn blit_bitmap( &mut self, pos: (i32, i32), _: (u32, u32), src: &[u8] ) -> Result<(), DrawingErrorKind<Self::ErrorType>>

Blit a bitmap on to the backend.
