# 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)
```js
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();
```
