You may try LEADTOOLS OCR SDK. With LEADTOOLS you can recognize PDF files and also you can save the result as searchable PDF. The code is as simple as this:
using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false))
{
ocrEngine.Startup(null, null, null, null);
string InputFileName = @"C:\temp\Input.pdf";
string OutputFileName = @"C:\temp\Output.pdf";
using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument())
{
IOcrPage ocrPage = ocrDocument.Pages.AddPage(InputFileName, null);
ocrPage.AutoZone(null);
ocrPage.Recognize(null);
ocrDocument.Save(OutputFileName, DocumentFormat.Pdf, null);
}
ocrEngine.Shutdown();
}
