Example

The following example will convert an image file to a PDF document.

using Leadtools; using Leadtools.Codecs; using Leadtools.Ocr; using Leadtools.Document.Writer; public void OcrEngineExample() { // 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.AutoZone(null); 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(); } } static class LEAD_VARS { public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; public const string OcrLEADRuntimeDir = @"C:\LEADTOOLS22\Bin\Common\OcrLEADRuntime"; }
