Expand description
Additional Node
methods.
Required methods
Returns node’s ID.
If a current node doesn’t support ID - an empty string will be returned.
Returns node’s transform.
If a current node doesn’t support transformation - a default transform will be returned.
fn abs_transform(&self) -> Transform
fn abs_transform(&self) -> Transform
Returns node’s absolute transform.
If a current node doesn’t support transformation - a default transform will be returned.
Returns node’s paint server units.
Returns None
when node is not a LinearGradient
, RadialGradient
or Pattern
.
fn append_kind(&mut self, kind: NodeKind) -> Node
fn append_kind(&mut self, kind: NodeKind) -> Node
Appends kind
as a node child.
Shorthand for Node::append(Node::new(Box::new(kind)))
.
fn calculate_bbox(&self) -> Option<PathBbox>
fn calculate_bbox(&self) -> Option<PathBbox>
Calculates node’s absolute bounding box.
Can be expensive on large paths and groups.
fn filter_background_start_node(&self, filter: &Filter) -> Option<Node>
fn filter_background_start_node(&self, filter: &Filter) -> Option<Node>
Returns the node starting from which the filter background should be rendered.
