Images are not in the right place


When previewing the Word file, we’re having problems with the images in the documents.
After a few investigations and tests on the parameters of the images in the Word file, nothing was really conclusive.

Please find enclosed:

You can see the problem on page 9 and 10 of the file R2401.0013.docx.

Here’s the code used for the preview

using GroupDocs.Viewer.Options;
using GroupDocs.Viewer.Results;
using System;
using System.IO;

namespace Web.code.Lib.GroupDocsViewer
    public class HtmlViewer : IDisposable
        private readonly GroupDocs.Viewer.Viewer viewer;
        private readonly HtmlViewOptions htmlViewOptions;
        private readonly ViewInfoOptions viewInfoOptions;

        private Stream stream;

        public HtmlViewer(string filePath, LoadOptions loadOptions)
            viewer = new GroupDocs.Viewer.Viewer(filePath, loadOptions);
            htmlViewOptions = CreateHtmlViewOptions();
            viewInfoOptions = ViewInfoOptions.FromHtmlViewOptions(htmlViewOptions);

        private HtmlViewOptions CreateHtmlViewOptions()
            HtmlViewOptions htmlViewOptions = HtmlViewOptions.ForEmbeddedResources(
                // The action that will be done before each page informations is read
                pageNumber =>
                    Stream pageStream = new MemoryStream();
                    stream = pageStream;

                    return pageStream;
                // The action to do after each page information is read.
                // Must be there otherwise the stream is disposed and we can't used it anymore
                (pageNumber, stream) =>

            htmlViewOptions.SpreadsheetOptions = SpreadsheetOptions.ForOnePagePerSheet();
            htmlViewOptions.SpreadsheetOptions.TextOverflowMode = TextOverflowMode.HideText;
            htmlViewOptions.SpreadsheetOptions.RenderHeadings = true;

            htmlViewOptions.ExcludeFonts = false;

            return htmlViewOptions;

        public string GetPageContent(int pageNumber)
            viewer.View(htmlViewOptions, pageNumber);
            stream.Position = 0;
            using (StreamReader reader = new StreamReader(stream))
                string htmlContent = reader.ReadToEnd();
                return htmlContent;

        public void Dispose()

Version of GroupDocs.Viewer used 24.3.0 (latest).

We’re developing a web application and your solution is being used by our application for customers who want to be able to preview and convert their files correctly.

Thanks in advance

Thanks for the package.
I have try to update it on own solution but when I have update the package, I have the following error :

Msg: Could not load file or assembly 'System.Text.Encoding.CodePages, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. 
The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040). 
StackTrace:    at   .()

   at GroupDocs.Viewer.Viewer.(ViewInfoOptions , CancellationToken )
   at GroupDocs.Viewer.Viewer.GetViewInfo(ViewInfoOptions options)
   at Web.code.Lib.GroupDocsViewer.HtmlViewer.GetViewInfo()

When I execute the following code :

var  viewer = new GroupDocs.Viewer.Viewer(filePath, loadOptions);
var htmlViewOptions = CreateHtmlViewOptions();
var viewInfoOptions = ViewInfoOptions.FromHtmlViewOptions(htmlViewOptions);
 ViewInfo viewInfo = viewer.GetViewInfo(viewInfoOptions);
 return viewInfo;

I can demo you if you want.
Thanks by advanced.


May you please share sample app to reproduce this issue?


Providing you with an example application would take too much time to redo.
Can I demonstrate the error in a meeting?


Unfortunately, we can only provide textual responses in Free Forum. Please share target framework, and OS that you’re running the app.

OK sure no problem.

We use a web application using .NET Framework 4.7.2 like target framework. For the OS, using IIS on Windows server.
The problem occurs when try to use the method viewer.GetViewInfo(viewInfoOptions);
The package System.Text.Encoding.CodePages is on version when dowloading your GroupDocs.Viewer Nuget package .


Thank you for sharing the details. We’ll take a look and update you.
