Implementations

impl VectorFont

pub fn from_path(path: &str) -> Result<Self, String>

Load a font from a TTF/OTF file using its default weight.

pub fn from_path_weight(path: &str, weight: Option<f32>) -> Result<Self, String>

Load a font, optionally pinning the variable-font weight axis (wght). The glyph cache lives at cache/fonts/<file-stem>[@<weight>]/.

pub fn from_bytes( bytes: Vec<u8>, name: &str, weight: Option<f32>, ) -> Result<Self, String>

pub fn ascent(&self) -> f32

pub fn descent(&self) -> f32

pub fn advance(&mut self, ch: char) -> f32

Normalized advance width of ch.

pub fn measure(&mut self, text: &str, px: f32) -> f32

Pixel width of text at size px.

pub fn glyph_outline(&mut self, ch: char, tol_em: f32) -> GlyphOutline

Flattened outline of ch, with curves subdivided so the deviation stays under tol_em (express your pixel tolerance as tol_px / px).
