Struct rsvg::image::Image

pub struct Image {
    aspect: AspectRatio,
    href: Option<String>,
}

The <image> element.

Note that its x/y/width/height are properties in SVG2, so they are defined as part of the properties machinery.

Fields

aspect: AspectRatio

href: Option<String>

Implementations

impl Image

fn layout_from_url( &self, url: &str, node: &Node<NodeData>, acquired_nodes: &mut AcquiredNodes<'_>, cascaded: &CascadedValues<'_>, viewport: &Viewport, draw_ctx: &mut DrawingCtx, ) -> Result<Option<Layer>, InternalRenderingError>

fn layout_from_surface( &self, surface: &SharedImageSurface, node: &Node<NodeData>, acquired_nodes: &mut AcquiredNodes<'_>, cascaded: &CascadedValues<'_>, viewport: &Viewport, draw_ctx: &mut DrawingCtx, ) -> Result<Option<Layer>, InternalRenderingError>

Draw an <image> from a raster image.

fn layout_from_svg( &self, document: &Document, node: &Node<NodeData>, acquired_nodes: &mut AcquiredNodes<'_>, cascaded: &CascadedValues<'_>, viewport: &Viewport, draw_ctx: &mut DrawingCtx, ) -> Result<Option<Layer>, InternalRenderingError>

Draw an <image> from an SVG image.

Per the spec, we need to rasterize the SVG (“The result of processing an ‘image’ is always a four-channel RGBA result.”) and then composite it as if it were a PNG or JPEG.

Trait Implementations

impl Default for Image

fn default() -> Image

Returns the “default value” for a type.

impl ElementTrait for Image

fn set_attributes(&mut self, attrs: &Attributes, session: &Session)

Sets per-element attributes.

fn layout( &self, node: &Node<NodeData>, acquired_nodes: &mut AcquiredNodes<'_>, cascaded: &CascadedValues<'_>, viewport: &Viewport, draw_ctx: &mut DrawingCtx, _clipping: bool, ) -> Result<Option<Layer>, InternalRenderingError>

Create a layout object for the current element.

fn draw( &self, node: &Node<NodeData>, acquired_nodes: &mut AcquiredNodes<'_>, cascaded: &CascadedValues<'_>, viewport: &Viewport, draw_ctx: &mut DrawingCtx, clipping: bool, ) -> Result<BoundingBox, InternalRenderingError>

Draw an element.
