ZingPDF.OCR

ZingPDF.OCR adds OCR support for scanned and image-based PDF pages.

Installation

dotnet add package ZingPDF.OCR

The built-in TesseractOcrEngine also needs Tesseract language data at runtime. See the official Tesseract documentation for setup details.

Quick start

using ZingPDF;
using ZingPDF.OCR;

using var pdf = Pdf.Load(File.OpenRead("scanned.pdf"));
var engine = new TesseractOcrEngine("./tessdata", "eng");

var text = await pdf.ExtractPlainTextWithOcrAsync(engine);

Main workflows

  • extract OCR text from scanned or image-based PDF pages
  • combine OCR with the main text extraction workflow
  • use the built-in TesseractOcrEngine or a custom IOcrEngine

Current limits

  • this package does not render arbitrary PDF drawing commands into an OCR image
  • OCR works on image-based pages and other pages with usable image XObjects
  • JPEG, JPEG 2000 passthrough, and common 8-bit RGB or grayscale image streams are the main supported inputs today
  • TesseractOcrEngine requires native Tesseract support and language data files at runtime

Licensing
