Image URL References Removed when using Word2016 Compatibility Mode

Aspose.Words Product Family

Hello,

I am trying to convert some HTML into a Word document and load it into Word Online. I found some code on another thread to skip the download of images:

public class SkipImageDownloadHandler : IResourceLoadingCallback
{
public ResourceLoadingAction ResourceLoading(ResourceLoadingArgs args)
{
String url = args.OriginalUri;
if (args.ResourceType == ResourceType.Image)
{
args.Uri = url;
return ResourceLoadingAction.Skip;
}

    return ResourceLoadingAction.Default;
}

}

Next up I am wanting to convert it into a word document (with compatibility options set to optimise for Word 2016 so it renders in Word Online). See the test code below:

[TestMethod]
public void Word2016_Image_Links_Test()
{
    var html = "<html><head></head><body><img src=\"https://cms.admin.containerize.com/templates/aspose/App_Themes/V3/images/aspose-logo.png\" /></body></html>";

    using (var inputStream = new MemoryStream())
    using (var inputWriter = new StreamWriter(inputStream))
    {
        inputWriter.Write(html);
        inputWriter.Flush();
        inputStream.Position = 0;

        var options = new Aspose.Words.LoadOptions
        {
            LoadFormat = Aspose.Words.LoadFormat.Html,
            ResourceLoadingCallback = new SkipImageDownloadHandler()
        };

        var asposeDoc = new Aspose.Words.Document(inputStream, options);

        // Note: if the line below is commented out then the images display fine
        asposeDoc.CompatibilityOptions.OptimizeFor(Aspose.Words.Settings.MsWordVersion.Word2016);

        asposeDoc.Save("c:\\temp\\converter-output.docx", Aspose.Words.SaveFormat.Docx);
    }
}

Previously when I ran this code I got an exception (which was fixed in WORDSNET-17646). Now when I run the code a document is created but the image does not display. When I run the output document through the Open XML SDK 2.5 Productivity Tool to check the contents, there is no reference to the image URL (the “aspose-logo.png” file mentioned above).

If I comment out the compatibility options line above then the images display fine and when I check them in the Open XML SDK Productivity Tool then the references to the image files are in the document as expected. I am wanting to create a document with 2016 compatibility mode and have it contain images as URLS.

Any advice would be appreciated.

Thanks for your inquiry. Please use the following code to get desired results. Hope,this helps.

var html = "<html><head></head><body><img src=\"https://cms.admin.containerize.com/templates/aspose/App_Themes/V3/images/aspose-logo.png\" /></body></html>";

using(var inputStream = new MemoryStream())
using(var inputWriter = new StreamWriter(inputStream)) {
  inputWriter.Write(html);
  inputWriter.Flush();
  inputStream.Position = 0;

  var options = new Aspose.Words.LoadOptions {
   LoadFormat = Aspose.Words.LoadFormat.Html,
    ResourceLoadingCallback = new SkipImageDownloadHandler()
  };

  var asposeDoc = new Aspose.Words.Document(inputStream, options);

  // Note: if the line below is commented out then the images display fine
  asposeDoc.CompatibilityOptions.OptimizeFor(Aspose.Words.Settings.MsWordVersion.Word2016);
  OoxmlSaveOptions saveOptions = new OoxmlSaveOptions {
   Compliance = OoxmlCompliance.Iso29500_2008_Strict,
    SaveFormat = SaveFormat.Docx
  };
  asposeDoc.Save("c:\\temp\\converter-output_19.1.docx", saveOptions);

public class SkipImageDownloadHandler: IResourceLoadingCallback {
 public ResourceLoadingAction ResourceLoading(ResourceLoadingArgs args) {
  String url = args.OriginalUri;
  if (args.ResourceType == ResourceType.Image) {
   args.Uri = url;
   return ResourceLoadingAction.Skip;
  }

  return ResourceLoadingAction.Default;
 }

}
