OCR a PDF document programmatically using C#

//Initialize the OCR processor by providing the path of tesseract binaries(SyncfusionTesseract.dll and liblept168.dll)
using (OCRProcessor processor = new OCRProcessor(@"TesseractBinaries\"))
{
//Load a PDF document
FileStream stream = new FileStream(@"Input.pdf", FileMode.Open);

//Load a PDF document
PdfLoadedDocument lDoc = new PdfLoadedDocument(stream);

//Set OCR language to process
processor.Settings.Language = Languages.English;

//Process OCR by providing the PDF document and Tesseract data
processor.PerformOCR(lDoc, @"TessData\");

//Save the OCR processed PDF document in the disk
FileStream fileStream = new FileStream("Sample.pdf", FileMode.CreateNew, FileAccess.ReadWrite);

//Save and close the PDF document 
lDoc.Save(fileStream);
