What is Content Stream?

Content Stream — Glosario

A sequence of operators and operands in a PDF that describe the appearance of text, graphics, and images on a page.

Detalle técnico

Content Stream works by analyzing pixel patterns in scanned or photographed text. Modern OCR engines like Tesseract use neural networks (LSTM architectures) trained on millions of character samples across hundreds of languages. The process involves binarization, skew correction, line segmentation, word segmentation, and character classification. Post-processing with language models and dictionaries improves accuracy beyond raw character recognition, typically achieving 95-99% accuracy on clean printed text.

Ejemplo

```javascript
// Content Stream: PDF manipulation example
import { PDFDocument } from 'pdf-lib';

const pdfDoc = await PDFDocument.load(fileBytes);
const pages = pdfDoc.getPages();
console.log(`Pages: ${pages.length}`);
```
