Struct pdf_writer::writers::EmbeddedFile

pub struct EmbeddedFile<'a> { /* fields omitted */ }

Writer for a embedded file stream.

This struct is created by PdfWriter::embedded_file.

Implementations

impl<'a> EmbeddedFile<'a>

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

Write the /Subtype attribute to set the file type.

This can either be a MIME type or a name prefixed by a first class PDF prefix. Note that special characters must be encoded as described in section 7.3.5 of the PDF 1.7 specification, e.g. image/svg+xml would become Name(b"image#2Fsvg+xml").

pub fn params(&mut self) -> EmbeddingParams<'_>

Start writing the /Params dictionary.

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

pub fn filter(&mut self, filter: Filter) -> &mut Self

Write the /Filter attribute.

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.

Trait Implementations

impl<'a> Deref for EmbeddedFile<'a>

type Target = Stream<'a>

The resulting type after dereferencing.

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

Dereferences the value.

impl<'a> DerefMut for EmbeddedFile<'a>

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

Mutably dereferences the value.
