Struct MathPicture 

pub struct MathPicture {
    pub svg: String,
    pub width: f64,
    pub height: f64,
    pub depth: f64,
}

A typeset formula: a standalone SVG document and where its baseline is. The peer of leaf_math::MathPicture; see typeset_math.

Fields

svg: String

A self-contained SVG — every glyph an outline, no font to find. Its viewBox, width and height are in pixels at the size it was typeset at, so drawn at its intrinsic size the glyphs land at that font size.

width: f64

The picture’s advance width, in em of the size it was typeset at.

height: f64

How far it rises above its baseline, in em — the ascent a run delegate reports, so the text baseline passes through the picture here.

depth: f64

How far it reaches below its baseline, in em — the descent.
