Struct rsvg::handle::Handle

pub struct Handle {
    session: Session,
    document: Document,
}

Main handle to an SVG document.

This is the main object in librsvg. It gets created with the from_stream method and then provides access to all the primitives needed to implement the public APIs.

Fields

session: Session

document: Document

Implementations

impl Handle

pub fn from_stream(
    session: Session,
    load_options: Arc<LoadOptions>,
    stream: &InputStream,
    cancellable: Option<&Cancellable>
) -> Result<Handle, LoadingError>

Loads an SVG document into a Handle.

pub fn has_sub(&self, id: &str) -> Result<bool, RenderingError>

Queries whether a document has a certain element #foo.

The id must be an URL fragment identifier, i.e. something like #element_id.

pub fn width_height_to_user(&self, dpi: Dpi) -> (f64, f64)

Normalizes the svg’s width/height properties with a 0-sized viewport

This assumes that if one of the properties is in percentage units, then its corresponding value will not be used. E.g. if width=100%, the caller will ignore the resulting width value.

fn get_node_or_root(
    &self,
    id: Option<&str>
) -> Result<Node<NodeData>, RenderingError>

fn geometry_for_layer(
    &self,
    node: Node<NodeData>,
    viewport: Rect,
    user_language: &UserLanguage,
    dpi: Dpi,
    is_testing: bool
) -> Result<(Rect, Rect), RenderingError>

pub fn get_geometry_for_layer(
    &self,
    id: Option<&str>,
    viewport: &Rectangle,
    user_language: &UserLanguage,
    dpi: Dpi,
    is_testing: bool
) -> Result<(Rectangle, Rectangle), RenderingError>

fn lookup_node(&self, id: &str) -> Result<Node<NodeData>, DefsLookupErrorKind>

pub fn render_document(
    &self,
    cr: &Context,
    viewport: &Rectangle,
    user_language: &UserLanguage,
    dpi: Dpi,
    is_testing: bool
) -> Result<(), RenderingError>

pub fn render_layer(
    &self,
    cr: &Context,
    id: Option<&str>,
    viewport: &Rectangle,
    user_language: &UserLanguage,
    dpi: Dpi,
    is_testing: bool
) -> Result<(), RenderingError>

fn get_bbox_for_element(
    &self,
    node: &Node<NodeData>,
    user_language: &UserLanguage,
    dpi: Dpi,
    is_testing: bool
) -> Result<BoundingBox, RenderingError>

pub fn get_geometry_for_element(
    &self,
    id: Option<&str>,
    user_language: &UserLanguage,
    dpi: Dpi,
    is_testing: bool
) -> Result<(Rectangle, Rectangle), RenderingError>

Returns (ink_rect, logical_rect)

pub fn render_element(
    &self,
    cr: &Context,
    id: Option<&str>,
    element_viewport: &Rectangle,
    user_language: &UserLanguage,
    dpi: Dpi,
    is_testing: bool
) -> Result<(), RenderingError>

pub fn get_intrinsic_dimensions(&self) -> IntrinsicDimensions

pub fn set_stylesheet(&mut self, css: &str) -> Result<(), LoadingError>
