Example
using Leadtools;
using Leadtools.Ocr;
using Leadtools.Document.Writer;
using Leadtools.Codecs;
public void CreateEngineExample()
{
// Create an instance of the engine
using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))
{
// Start the engine using default parameters
ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir);
string tifFileName = Path.Combine(LEAD_VARS.ImagesDir, "Ocr1.tif");
string pdfFileName = Path.Combine(LEAD_VARS.ImagesDir, "Ocr1.pdf");
// Create an OCR document
using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument())
{
// Add a page to the document
IOcrPage ocrPage = ocrDocument.Pages.AddPage(tifFileName, null);
// Recognize the page
// Note, Recognize can be called without calling AutoZone or manually adding zones. The engine will
// check and automatically auto-zones the page
ocrPage.Recognize(null);
// Save the document we have as PDF
ocrDocument.Save(pdfFileName, DocumentFormat.Pdf, null);
}
// Shutdown the engine
// Note: calling Dispose will also automatically shutdown the engine if it has been started
ocrEngine.Shutdown();
}
