pub fn leading(&mut self, leading: f32) -> &mut Self

Write the /Leading attribute.

pub fn cap_height(&mut self, cap_height: f32) -> &mut Self

Write the /CapHeight attribute. Required for fonts with Latin characters, except for Type 3 fonts.

pub fn x_height(&mut self, x_height: f32) -> &mut Self

Write the /XHeight attribute.

pub fn stem_v(&mut self, stem_v: f32) -> &mut Self

Write the /StemV attribute. Required, except for Type 3 fonts.

pub fn stem_h(&mut self, stem_h: f32) -> &mut Self

Write the /StemH attribute.

pub fn avg_width(&mut self, avg_width: f32) -> &mut Self

Write the /AvgWidth attribute.

pub fn max_width(&mut self, max_width: f32) -> &mut Self

Write the /MaxWidth attribute.

pub fn missing_width(&mut self, missing_width: f32) -> &mut Self

Write the /MissingWidth attribute.

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

Write the /FontFile attribute, referecing Type 1 font data.

pub fn font_file2(&mut self, id: Ref) -> &mut Self

Write the /FontFile2 attribute, referencing TrueType font data. PDF 1.1+.

pub fn font_file3(&mut self, id: Ref) -> &mut Self

Write the /FontFile3 attribute, referencing CFF font data. PDF 1.2+ or PDF 1.3+ for CID-keyed fonts.

pub fn char_set(&mut self, names: Str<'_>) -> &mut Self

Write the /CharSet attribute, encoding the character names of a font subset as a string. This is only relevant for Type 1 fonts. PDF 1.1+.

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.
