Shakeer,

The code that I sent you uses OCR features from LEADTOOLS programming toolkit. To include and use the code snippet in your project, you need first to download and install the LEADTOOLS SDK.
You can download it from the following page:
https://www.leadtools.com/downloads?category=main
After this, the following link shows the required DLLs (assemblies) you need to include as references in your project:

If you still need any information about LEADTOOLS programming toolkit, you can contact support at [email protected].

I hope this helps :)

Thanks for your responces,

In Below Login "IOcrEngine" will get the add namespace.So can you plz suggest namespace and DLL which is support to c#.net below code working.

using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
{
RasterCodecs _codecs = new RasterCodecs();
// Start the engine
ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS 19\Bin\Common\OcrAdvantageRuntime")

Below path iam not understand is it any run 3rd party tool run muy system.

ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS 19\Bin\Common\OcrAdvantageRuntime");

You can try using one of LEADTOOLS OCR engines to recognize the text in the source DOC or PDF images, and then save the result as Text format.
The following code shows how you can do this using LEADTOOLS OCR Advantage engine:
string sPath = @"C:\Source\Source.doc";

if (System.IO.File.Exists(sPath))
{
string extension = System.IO.Path.GetExtension(sPath).ToLower();
string txtResult = sPath.Replace(extension, ".txt");

using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
{
RasterCodecs _codecs = new RasterCodecs();
// Start the engine
ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS 19\Bin\Common\OcrAdvantageRuntime");

_codecs.Options.RasterizeDocument.Load.XResolution = 300;
_codecs.Options.RasterizeDocument.Load.YResolution = 300;
_codecs.Options.Load.AllPages = true;
// Create an OCR document
using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument())
{
RasterImage _docImage = _codecs.Load(sPath);
// Add this image to the document
ocrDocument.Pages.AddPages(_docImage, 1,_docImage.PageCount,null);
ocrDocument.Pages.AutoZone(null);
// Recognize it and save it as Text
ocrDocument.Pages.Recognize(null);
ocrDocument.Save(txtResult, DocumentFormat.Text, null);
}
ocrEngine.Shutdown();
}
}
I am attaching the result text file that I got after recognizing the source DOC file using LEADTOOLS SDK.

Hey,

try this

byte[] imageArray = System.IO.File.ReadAllBytes(@"Path of the image");
string base64ImageRepresentation = Convert.ToBase64String(imageArray);
using (StreamWriter writer = new StreamWriter(@"C:\ccon\abc.txt", true))
{
writer.Write(base64ImageRepresentation);
writer.Flush();
writer.Close();
}
