Struct NumberTree

pub struct NumberTree<'a, T> { /* private fields */ }

Writer for a number tree node.

Number trees associate a many integers with PDF objects. They are search trees in ascending order. Root nodes may directly contain all leafs, however, this might degrade performance for very large numbers of integer-object pairs.

For each node, either the /Kids or /Nums attribute must be set, but never both.

Implementations

impl<T> NumberTree<'_, T>

pub fn kids(&mut self) -> TypedArray<'_, Ref>

Start writing the /Kids attribute with the children of this node.

pub fn nums(&mut self) -> NumberTreeEntries<'_, T>

Start writing the /Nums attribute to set the immediate number-to-object mappings of this node.

pub fn limits(&mut self, min: i32, max: i32) -> &mut Self

Write the /Limits array to set the range of numbers in this node. This is required for every node except the root node.

Trait Implementations

impl<'a, T> Writer<'a> for NumberTree<'a, T>

fn start(obj: Obj<'a>) -> Self
