Help with c # programming

Question

Hello, I need help with converting an image to text. I' am using c #.

Answer 1

In general (Like cheong00 mentioned), the source files could either contain text or contain images of text. There is a solution that can handle both types of source files, which is the LEADTOOLS Document Converter SDK Libraries. (Disclaimer: I am a LEADTOOLS employee).

The following code converts many types of input files and images to text, and automatically invoked OCR if needed:

private void ConvertToText(string inputFileName)
{
   var options = new LoadDocumentOptions();
   using (var document = DocumentFactory.LoadFromFile(inputFileName, options))
   {
      using (DocumentConverter documentConverter = new DocumentConverter())
      {
         Leadtools.Ocr.IOcrEngine ocrEngine = Leadtools.Ocr.OcrEngineManager.CreateEngine(Leadtools.Ocr.OcrEngineType.LEAD);
         ocrEngine.Startup(null, null, null, ocrEnginePath);
         documentConverter.SetOcrEngineInstance(ocrEngine, false);
         var outFile = inputFileName + "_converted.txt";
         var format = Leadtools.Document.Writer.DocumentFormat.Text;
         var jobData = DocumentConverterJobs.CreateJobData(document, outFile, format);
         jobData.JobName = "conversion job";
         var job = documentConverter.Jobs.CreateJob(jobData);
         documentConverter.Jobs.RunJob(job);
         MessageBox.Show(job.Errors.Count.ToString() + " " + outFile);
      }
   }
}

Unless you're processing images that have original text embedded (say, PS/AI/CDX/etc.), you'll need to employ some OCR technologies to deduce what are the text on the image.

If you're developing for UWP, you may also consider classes from the Windows.Media.Ocr namespace.
