Struct pdf_writer::writers::Type3Font

pub struct Type3Font<'a> { /* private fields */ }

Writer for a Type-3 font dictionary.

This struct is created by Chunk::type3_font.

Implementations

impl<'a> Type3Font<'a>

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

Write the /Name attribute, which is the name of the font in the current resource dictionary. Required in PDF 1.0, discouraged in PDF 1.1+.

pub fn bbox(&mut self, bbox: Rect) -> &mut Self

Write the /FontBBox attribute. Required.

pub fn matrix(&mut self, matrix: [f32; 6]) -> &mut Self

Write the /FontMatrix attribute, which defines the mapping from glyph space to text space. Required.

pub fn char_procs(&mut self) -> TypedDict<'_, Ref>

Start writing the /CharProcs dictionary, which maps glyph names to glyph content streams. Required.

Each glyph’s content stream must start with either the d0 or d1 operator.

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

Write the /Encoding attribute as a predefined encoding. Either this or encoding_custom is required.

pub fn encoding_custom(&mut self) -> Encoding<'_>

Start writing an /Encoding dictionary. Either this or encoding_predefined is required.

pub fn first_char(&mut self, first: u8) -> &mut Self

Write the FirstChar attribute, defining the first character code in the font’s widths array. Required.

pub fn last_char(&mut self, last: u8) -> &mut Self

Write the LastChar attribute, defining the last character code in the font’s widths array. Required.

pub fn widths(&mut self, widths: impl IntoIterator<Item = f32>) -> &mut Self

Write the /Widths array. Should be of length last - first + 1. Required.

pub fn font_descriptor(&mut self, id: Ref) -> &mut Self

Write the /FontDescriptor attribute. Required in Tagged PDFs.

pub fn resources(&mut self) -> Resources<'_>

Start writing the /Resources dictionary.

pub fn to_unicode(&mut self, id: Ref) -> &mut Self

Write the /ToUnicode attribute. PDF 1.2+.

A suitable character map can be built with UnicodeCmap.

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.
