Struct EpaintLayout 

pub struct EpaintLayout {
    typeface: FontChoice,
    fonts: RefCell<Fonts>,
}

A standalone [Fonts] with the app’s faces installed — the very engine that lays the diagram out on screen, driven without a Context.

Fields

typeface: FontChoice

fonts: RefCell<Fonts>

Laying out needs &mut; the font atlas it fills along the way is never read.

Implementations

impl EpaintLayout

pub fn new(typeface: FontChoice) -> Self

Trait Implementations

impl TextLayout for EpaintLayout

fn typeface(&self) -> FontChoice

The typeface this engine lays text out in. The SVG export traces its outlines from that face’s own bytes, so an engine that answered for a different one would place one font’s glyphs at another’s pen positions.

fn layout(&self, text: &str, font: &Font, wrap: WorldPx) -> Layout

Lay text out in font, word-wrapped at wrap ([WorldPx::UNBOUNDED] for an unwrapped run). An exporter’s engine lays out at one pixel per point, so a resolution-independent format inherits no display’s DPI; the screen’s lays out at the display’s, so a mark recorded through it lands where the screen draws it.
