This Visual Studio 2017 console project uses LEADTOOLS v20 Leadtools.Ocr.NETStandard nuget package to illustrate the minimum code required to OCR single page or multi-page files and save it as a plain text (TXT), Portable Document Format (PDF), or LEAD Temporary Document file (LTD).

The demo uses command line arguments to set the input file, output file, and output document type. Here are example argument lists:
-i "C:\Users\Public\Documents\LEADTOOLS Images\Leadtools.pdf" -o "D:\junk folder\Leadtools.pdf.txt" -f TXT
-i "C:\Users\Public\Documents\LEADTOOLS Images\OCR1.TIF" -o "C:\OCR1.pdf" -f PDF

The core OCR code can be summed up in a few lines:
Code:

codecs.Options.Load.AllPages = true;
image = codecs.Load(inputFile);

ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false);
ocrEngine.Startup(codecs, null, null, OCR_ENGINE_PATH);

ocrDocument = ocrEngine.DocumentManager.CreateDocument();
ocrDocument.Pages.AddPages(image, 1, image.PageCount, null);
foreach (Leadtools.Ocr.IOcrPage page in ocrDocument.Pages)
   page.Recognize(null);
            
ocrDocument.Save(outputFile, format, null);

Before running this demo, please verify the DEVELOPER_LIC and DEVELOPER_KEY file paths exist and change the application arguments if desired.
