Struct Renderer

pub struct Renderer { /* private fields */ }

A tiny-skia graphics renderer for iced.

Implementations

impl Renderer

pub fn new(default_font: Font, default_text_size: Pixels) -> Self

pub fn layers(&mut self) -> &[Layer]

pub fn draw<T: AsRef<str>>( &mut self, pixels: &mut PixmapMut<'_>, clip_mask: &mut Mask, viewport: &Viewport, damage: &[Rectangle], background_color: Color, overlay: &[T], )

Trait Implementations

fn end_transformation(&mut self)

Ends recording a new layer.

fn fill_quad(&mut self, quad: Quad, background: impl Into<Background>)

Fills a [Quad] with the provided [Background].

fn clear(&mut self)

Clears all of the recorded primitives in the [Renderer].

fn with_layer(&mut self, bounds: Rectangle, f: impl FnOnce(&mut Self))

Draws the primitives recorded in the given closure in a new layer.

fn with_transformation( &mut self, transformation: Transformation, f: impl FnOnce(&mut Self), )

Applies a [Transformation] to the primitives recorded in the given closure.

fn with_translation(&mut self, translation: Vector, f: impl FnOnce(&mut Self))

Applies a translation to the primitives recorded in the given closure.

impl Renderer for Renderer

const ICON_FONT: Font

The icon font of the backend.

const CHECKMARK_ICON: char = '\u{f00c}'

The char representing a ✔ icon in the ICON_FONT.

const ARROW_DOWN_ICON: char = '\u{e800}'

The char representing a ▼ icon in the built-in ICON_FONT.

type Font = Font

The font type used.

type Paragraph = Paragraph

The [Paragraph] of this [Renderer].

type Editor = Editor

The [Editor] of this [Renderer].

fn default_font(&self) -> Self::Font

Returns the default [Self::Font].

fn default_size(&self) -> Pixels

Returns the default size of [Text].

fn fill_paragraph( &mut self, text: &Self::Paragraph, position: Point, color: Color, clip_bounds: Rectangle, )

Draws the given [Paragraph] at the given position and with the given [Color].

fn fill_editor( &mut self, editor: &Self::Editor, position: Point, color: Color, clip_bounds: Rectangle, )

impl Renderer for Renderer

Available on crate feature geometry only.

type Geometry = Geometry

The kind of geometry this renderer can draw.

type Frame = Frame

The kind of [Frame] this renderer supports.

fn new_frame(&self, size: Size) -> Self::Frame

Creates a new [Self::Frame].

fn draw_geometry(&mut self, geometry: Self::Geometry)

type Handle = Handle

The image Handle to be displayed. Iced exposes its own default implementation of a Handle

fn measure_image(&self, handle: &Self::Handle) -> Size<u32>

Returns the dimensions of an image for the given [Handle].

fn draw_image(&mut self, image: Image, bounds: Rectangle)
