How to select which pages to perform OCR? I have 100 pages PDF but want to perform OCR on page range 1-50.

var loadedDocument = new PdfLoadedDocument(@"c:\test.pdf")

processor.PerformOCR(loadedDocument, Path.Combine(AppConstants.ConverterBinPath, @"Tesseract\Tessdata"));

Hi Marek,

Thank you for contacting Syncfusion support.

We can able to perform OCR on particular range of page using PerformOCR overload. Please refer the below code snippet for more details,

//Load a PDF document

PdfLoadedDocument lDoc = new PdfLoadedDocument("Input.pdf");

//Set OCR language to process

processor.Settings.Language = Languages.English;

//Process OCR by providing the PDF document, start page, end page and Tesseract data

string str = processor.PerformOCR(lDoc, 0, 49, @"Tessdata");

Please refer the below documentation link for more details about the overloads in PerformOCR method,

Please try the above solution in your end and let us know the result.

Regards,

Sowmiya Loganathan
