svg2pdf-wasm Documentation

📌 Overview

svg2pdf-wasm is a WebAssembly-compatible Rust package that allows you to:

• Convert SVG to PDF.
• Add custom text using a loaded Base64 font.
• Export the final PDF as a byte array (Vec<u8>) for client-side use.

This package is designed for WASM/WebAssembly environments, allowing SVG-PDF conversion directly in web apps.

🎯 Example Usage (Complete Flow)

import init, {
  PdfConverter,
  svg_to_pdf_sync,            // if you built without threads
  svg_to_pdf_threaded,        // only present with `--features threads`
  init_thread_pool            // only present with `--features threads`
} from "svg2pdf-wasm";
navigator.hardwareConcurrency // must be ≥2
async function generatePDF() {
    
    await init();

    // THREADS BUILD
    if (init_thread_pool) {
      await init_thread_pool(navigator.hardwareConcurrency || 4);
    }

    const base64SVG = "PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwv...";
    const base64Font = "UEsFBgAAAAAAAAAAAAAAAAAAAAAAAA=="; 

    const converter = new PdfConverter();
    await converter.load_base64_font(base64Font);

    const pdfData = await converter.svg_to_pdf_threaded(base64SVG, 1.0);
    // await converter.svg_to_pdf_sync(base64SVG, 1.0);
    const blob = new Blob([pdfData], { type: "application/pdf" });
    const url = URL.createObjectURL(blob);
    window.open(url);
}

generatePDF();
