Font Embedding
PDF Font Embedding
Including font data within a PDF file so the document renders correctly regardless of fonts installed on the viewer's system.
Détail technique
In the PDF specification (ISO 32000-2:2020), font embedding is implemented as a specialized object within the document's object graph. PDF files use a cross-reference table to index every object by byte offset, enabling random access without sequential parsing. This architecture allows font embedding to be read, modified, or extracted independently of other document elements. The binary structure supports incremental saves, where changes append to the file without rewriting existing content.
Exemple
```javascript
// Font Embedding: PDF manipulation example
import { PDFDocument } from 'pdf-lib';
const pdfDoc = await PDFDocument.load(fileBytes);
const pages = pdfDoc.getPages();
console.log(`Pages: ${pages.length}`);
```
