Trait Implementations

impl Clone for NullScenePainter

fn clone(&self) -> NullScenePainter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NullScenePainter

impl Default for NullScenePainter

fn default() -> NullScenePainter

Returns the “default value” for a type.

impl PaintScene for NullScenePainter

fn reset(&mut self)

Removes all content from the scene

fn push_layer( &mut self, _blend: impl Into<BlendMode>, _alpha: f32, _transform: Affine, _clip: &impl Shape, _filter: Option<Arc<Filter>>, _backdrop_filter: Option<Arc<Filter>>, )

Pushes a new layer clipped by the specified shape and composed with previous layers using the specified blend mode. Every drawing command after this call will be clipped by the shape until the layer is popped. However, the transforms are not saved or modified by the layer stack.

fn push_clip_layer(&mut self, _transform: Affine, _clip: &impl Shape)

Pushes a new clip layer clipped by the specified shape. Every drawing command after this call will be clipped by the shape until the layer is popped. However, the transforms are not saved or modified by the layer stack.

fn pop_layer(&mut self)

Pops the current layer.

fn stroke<'a>( &mut self, _style: &Stroke, _transform: Affine, _brush: impl Into<PaintRef<'a>>, _brush_transform: Option<Affine>, _shape: &impl Shape, )

Strokes a shape using the specified style and brush.

fn fill<'a>( &mut self, _style: Fill, _transform: Affine, _brush: impl Into<PaintRef<'a>>, _brush_transform: Option<Affine>, _shape: &impl Shape, )

Fills a shape using the specified style and brush.

fn draw_glyphs<'a, 's: 'a>( &'s mut self, _font: &'a FontData, _font_size: f32, _hint: bool, _normalized_coords: &'a [NormalizedCoord], _embolden: Vec2, _style: impl Into<StyleRef<'a>>, _brush: impl Into<PaintRef<'a>>, _brush_alpha: f32, _transform: Affine, _glyph_transform: Option<Affine>, _glyphs: impl Iterator<Item = Glyph>, )

Draws a run of glyphs

fn draw_box_shadow( &mut self, _transform: Affine, _rect: Rect, _brush: Color, _radius: f64, _std_dev: f64, )

Draw a rounded rectangle blurred with a gaussian filter.

fn append_scene(&mut self, scene: Scene, scene_transform: Affine)

Append a recorded Scene Fragment to the current scene

fn draw_image(&mut self, image: ImageBrushRef<'_>, transform: Affine)

Utility method to draw an image at it’s natural size. For more advanced image drawing use the fill method

impl RenderContext for NullScenePainter

fn try_register_custom_resource( &mut self, resource: Box<dyn Any>, ) -> Result<ResourceId, RegisterResourceError>

fn unregister_resource(&mut self, resource_id: ResourceId)

fn renderer_specific_context(&self) -> Option<Box<dyn Any>>

Return a type-erased context type that is passed to custom widgets in order to enable them to render renderer-specific content
