Please note that the core API feature is to convert the source file to PDF, HTML or Image file format and save it to the directory or return result in stream. Later, it’s up to you to render the converted file in browser or any application (e.g. Windows form).
For example, have a look at the following code:

string outputDirectory = "output directory";
string pageFilePathFormat = Path.Combine(outputDirectory, "page_{0}.png");
 using (Viewer viewer = new Viewer("sample.docx"))
 {
       PngViewOptions options = new PngViewOptions(pageFilePathFormat);
       viewer.View(options);
}

Now, in the this code, API is taking a source file as input (Word file), converting it to PNG and saving to output directory. Next, you have to render the output PNG in browser.
Have a look at this sample ASP.NET MVC Document Viewer application.

Thank you for your response @Atir_Tahir, I am working on .Net framework 4.7.2 so given code is not working on the same .net framework so could you please give me the solution for same framework.

We couldn’t reproduce this issue/error at our end. Have a look at this screencast.zip (2.4 MB).

Have a look at the supported .NET frameworks or the minimum system requirements. Could you please share your application using that we could reproduce this issue?

Ok Let me check from my end and if i need to open png/pdf in viewer in browser then what should I have do?

@passion.avp

You just have to pass that file/format to Viewer. Have a look at this video.

@Atir_Tahir,I need to implement urgently because I have purchased $999 license 1 month ago and stucked on above implementation.

That application demonstrates the basic or the core API functionality.

However, we do have an open-source ASP.NET MVC project that gives you following (but not limited to) features:

  • Download documents
  • Upload documents
  • Print document
  • Rotate pages
  • Zoom in/out documents without quality loss in HTML mode
  • Thumbnails
  • Smooth page navigation

Have a look at this video demo. Download this project here.

  3. Please give me straight forward solution to implement document view with zoomIn,

As you know that the API is UI-Agnostic. There are no such (e.g. zoom in, download) built-in features. However, they could be added in the front-end project using JS. For example, below code could be used to zoom in and out:

function zoomIn()
{
  var Page = document.getElementById('Body');
  var zoom = parseInt(Page.style.zoom) + 5 +'%'
  Page.style.zoom = zoom;
  return false;
}

function zoomOut()
{
  var Page = document.getElementById('Body');
  var zoom = parseInt(Page.style.zoom) - 5 +'%'
  Page.style.zoom = zoom;
  return false;
}

In order to make you a working solution with such a features, we need time. Please note that all free support issues are handled at first come first served basis. So, we couldn’t commit any ETA at the moment.
