Content added to PowerPoint footer is not visible

GroupDocs.Viewer Product Family

Hi, our clients complaining that content added to PowerPoint footer is not visible. Attaching file here for you to test out.

It’s happening to our application using GroupDocs.Viewer, and this could be easily reproduced in your cloud too:
https://products.groupdocs.app/viewer/app/?lang=en&file=e003ea06-9a55-4d14-836a-fb6bb660bced%2FTest%20presentation.pptx

Just upload the file there and you’ll see that text added in the middle of footer is not visible on preview, but visible in real presentation in edit mode and in presentation mode as well.

Can you please resolve a problem in library and release a new version, or if there any way to fix it with additional parameters of type library let me know.

Hi Matt,

Thank you for providing the sample PPTX, we’ve reproduced the issue when rendering this PPTX to all output formats, including HTML. Our developers have started to work on it. We will notify you when there will be some update on this issue.

With best regards,

Hi Matt,

Today the GroupDocs.Viewer for .NET 25.11 was released, and the discussed issue is fixed there. You should use the PresentationOptions.RenderHeaderFooterPlaceholders flag to enable rendering placeholders in the headers/footers of the slide, like this (rendering to HTML as an example):

const string filename = "Test presentation.pptx";
string inputFilePath = Path.Combine("files", filename);
HtmlViewOptions htmlViewOptions = HtmlViewOptions.ForEmbeddedResources(string.Format("{0}-embedded-page-{{0}}.html", Path.GetFileNameWithoutExtension(filename)));
htmlViewOptions.PresentationOptions.RenderHeaderFooterPlaceholders = true;
using (Viewer viewer = new Viewer(inputFilePath))
{
    viewer.View(htmlViewOptions);
}

With best regards,
Denis Gvardionov
