Struct Latex 

Source
pub struct Latex {
    formula: String,
    size_pt: f32,
    position: Option<Position>,
    alignment: Alignment,
    inline: bool,
}
Expand description

A LaTeX formula element that renders mathematical expressions using MicroTeX.

§Examples

Basic usage:

use genpdfi_extended::elements;

let formula = elements::Latex::new(r#"E = mc^2"#, 12.0);

With alignment:

use genpdfi_extended::elements;
use genpdfi_extended::Alignment;

let formula = elements::Latex::new(r#"\[E = mc^2\]"#, 14.0)
    .with_alignment(Alignment::Center);

Fields§

§formula: String

The LaTeX formula source code

§size_pt: f32

Font size in “pseudo” points (equivalent to text font size)

§position: Option<Position>

Optional explicit position (overrides alignment)

§alignment: Alignment

Horizontal alignment when not positioned explicitly

§inline: bool

Whether to render inline (within text flow) or as a block

Implementations§

Source§

impl Latex

Source

pub fn new(formula: impl Into<String>, size_pt: f32) -> Self

Creates a new LaTeX formula element.

§Arguments
  • formula - The LaTeX source code to render
  • size_pt - Font size in “pseudo” points (e.g., 12.0 for 12pt)
§Example
use genpdfi_extended::elements;
let formula = elements::Latex::new(r#"x^2 + y^2 = z^2"#, 14.0);
Source

pub fn with_position(self, position: Position) -> Self

Sets explicit positioning, overriding alignment.

Source

pub fn with_alignment(self, alignment: Alignment) -> Self

Sets horizontal alignment (used when position is not explicitly set).

Source

pub fn inline(self) -> Self

Marks this formula for inline rendering (integrated into text flow).

Source

pub fn block(self) -> Self

Marks this formula for block rendering (on its own line).

Source

fn render_to_scaled_svg(&self) -> Result<String, Error>

Renders the LaTeX formula to SVG using MicroTeX and applies scaling. Uses a global singleton MicroTeX instance (initialized only once).
