pub fn is_builtin(&self) -> bool

Returns whether this font is a built-in PDF font.

pub fn get_line_height(&self, font_size: u8) -> Mm

Returns the line height for text with this font and the given font size.

pub fn glyph_height(&self, font_size: u8) -> Mm

Returns the glyph height for text with this font and the given font size.

pub fn char_width(&self, font_cache: &FontCache, c: char, font_size: u8) -> Mm

Returns the width of a character with this font and the given font size.

The given FontCache must be the font cache that loaded this font.

pub fn str_width(&self, font_cache: &FontCache, s: &str, font_size: u8) -> Mm

Returns the width of a string with this font and the given font size.

The given FontCache must be the font cache that loaded this font.

pub fn kerning<I>(&self, font_cache: &FontCache, iter: I) -> Vec<f32> where
    I: IntoIterator<Item = char>, 

Returns the kerning data for the given sequence of characters.

The i-th value of the returned data is the amount of kerning to insert before the i-th character of the sequence.

The given FontCache must be the font cache that loaded this font.

pub fn glyph_ids<I>(&self, font_cache: &FontCache, iter: I) -> Vec<u16> where
    I: IntoIterator<Item = char>, 

Returns the glyphs IDs for the given sequence of characters.

The given FontCache must be the font cache that loaded this font.
