Resource name (e.g., “F1”)

§base_font: String

Base font name (e.g., “Helvetica”, “ArialMT”)

§subtype: String

Font subtype (Type1, TrueType, Type0, Type3)

§widths: HashMap<u32, f64>

Glyph widths indexed by character code

§default_width: f64

Default width for missing glyphs

§to_unicode: HashMap<u32, String>

ToUnicode mapping: character code → Unicode string

§encoding: String

Encoding name

§is_standard: bool

Whether this is a standard 14 font

§flags: u32

Font descriptor flags

§italic_angle: f64

Italic angle

§weight: f64

Font weight (estimated)

§bytes_per_code: u8

Bytes per character code (1 for Type1/TrueType, 2 for Type0/CID)

§ascent: f64

Font ascent in glyph-space units (per-mille, i.e. 1000 = 1 em)

§descent: f64

Font descent in glyph-space units (negative, per-mille)

§font_bbox: [f64; 4]

Font bounding box [llx, lly, urx, ury] in glyph-space units

Implementations§

Source §

impl PdfFont

Source

pub fn default_font(name: &str) -> Self

Create a default font with standard metrics.

Source

pub fn glyph_width(&self, char_code: u32) -> f64

Source

pub fn decode_char(&self, char_code: u32) -> String

Get Unicode string for a character code.

Source

pub fn is_bold(&self) -> bool

Whether the font is bold (estimated from name or flags).

Source

pub fn is_italic(&self) -> bool

Whether the font is italic (estimated from name or italic angle).
