Struct DeveloperExtension

pub struct DeveloperExtension<'a> { /* private fields */ }

Writer for a developer extension dictionary. PDF 1.7+.

An array of this struct is created by Catalog::extensions.

Implementations

impl<'a> DeveloperExtension<'a>

pub fn base_version(&mut self, major: u8, minor: u8) -> &mut Self

Write the /BaseVersion attribute to specify the version of PDF this extension is based on. Required.

pub fn extension_level(&mut self, level: i32) -> &mut Self

Write the /ExtensionLevel attribute to specify the version of the extension. Required.

Methods from Deref<Target = Dict<'a>>

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn insert(&mut self, key: Name<'_>) -> Obj<'_>

Start writing a pair with an arbitrary value.

pub fn pair<T: Primitive>(&mut self, key: Name<'_>, value: T) -> &mut Self

Write a pair with a primitive value.

This is a shorthand for dict.insert(key).primitive(value).

pub fn pairs<'n, T: Primitive>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)>, ) -> &mut Self

Write a sequence of pairs with primitive values.
