Implementations

impl Standard14

pub const ALL: [Standard14; 14]

All fourteen, in ISO 32000 listing order.

pub fn base_font(self) -> &'static str

The PostScript base font name, e.g. "Helvetica-Bold".

pub fn from_base_font(name: &str) -> Option<Standard14>

Parses a PostScript base font name back to the variant. Exact names only — aliases and subset-tagged forms are the reading side’s business, not the writer’s.

pub fn encode(self, text: &str) -> Result<Vec<u8>>

Encodes text to font code bytes: WinAnsi for the twelve text faces, the font-specific built-in encoding for Symbol and ZapfDingbats. A character without a code is an Error::Unencodable (crate::Error::Unencodable) — never silently dropped or replaced. Symbol and ZapfDingbats currently reject every character: their encoding tables come with a later phase.

pub fn width(self, ch: char) -> Option<f32>

Advance width of one character in units per 1000 of font size, from the AFM metrics. None when the character has no code or metric.

pub fn text_width(self, text: &str, size: f32) -> Result<f32>

Width of a whole string at size, in text-space units. Errors on unencodable characters, like encode; an encodable character whose glyph has no AFM metric is an Error::Other naming the glyph. No kerning — the AFM kern pairs are not bundled, so this is the sum of bare advance widths.
