Automatic rotation of JPEG images based on Exif Orientation tag
Unlink table of contents in Word documents

Automatic rotation of JPEG images based on Exif Orientation tag

GroupDocs.Viewer for .NET automatically rotates and flips JPEG images based on Exif orientation metadata. This ensures that you always see images in the correct orientation, regardless of how they were captured or stored. For instance, GroupDocs.Viewer for .NET automatically rotated the following image 180 degrees to display it correctly.

Unlink table of contents in Word documents

When rendering to HTML or PDF, you can set WordProcessingOptions.UnlinkTableOfContents to true to unlink table of contents. For HTML rendering, <a> tags with relative links will be replaced with <span> tags, removing functionality but preserving visual appearance. For PDF rendering, the table of contents will be rendered as plain text without links to document sections.

The code example below renders a Word document with table of contents as a plain text without links.

using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;
// ...

using (var viewer = new Viewer("resume.docx"))
{
    // Convert the document to HTML.
    var viewOptions = HtmlViewOptions.ForEmbeddedResources();
    // Unlink table of contents.
    viewOptions.WordProcessingOptions.UnlinkTableOfContents = true;
    viewer.View(viewOptions);
}

The following image illustrates the result:
