Struct 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. Always required in PDF 1.0, required if FontName is set in child font descriptor.

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.

This attribute is required in some profiles of PDF/A-2, PDF/A-3, and PDF/A-4 for some fonts. When present, these standards require that no character may be mapped to 0, U+FEFF, or U+FFFE.

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.
