Struct pdf_writer::writers::Encoding

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

Writer for a simple font encoding dictionary.

This struct is created by Type1Font::encoding_custom and Type3Font::encoding_custom.

Implementations

impl<'a> Encoding<'a>

pub fn base_encoding(&mut self, name: Name<'_>) -> &mut Self

Write the BaseEncoding attribute, from which this encoding is described through differences.

pub fn differences(&mut self) -> Differences<'_>

Start writing the /Differences array.

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

pub fn len(&self) -> i32

The number of written pairs.

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.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> DerefMut for Encoding<'a>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'a> Writer<'a> for Encoding<'a>

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