Embedded Icon Is Not Rendered for Embedded Word Document with Embedded Excel File when Converting PPTX to PDF in C#

Aspose.Slides Product Family

The Excel file is being displayed as an icon in the Word doc, which is embedded and rendered as a document in the PPT file. I can get the icon to display if I set the .IsObjectIcon property to ‘True’ on the embedded Word doc OleObjectFrame, but it appears to render the Word doc as a small icon, then expand it to the size of the embedded object, making the document contents blurry and unreadable.
I was able to use Aspose.Words to read the bytes of and open the embedded word document, and through that get to the Excel file, but that seems a bit extreme to simply render an icon.

Other software doesn’t have issues rendering this icon.

I can’t upload a sample, but here are screenshots of the document rendered by PPT automation to an imaging print driver, and Aspose.Slides rendered.

Sample file attached.

I am using the Aspose.Slide.Net Nuget package version 22.12.0

public void SampleCode()
{
    string sampleFilePath = @"C:\temp\sampleFile.PPT";
    var docStream = File.OpenRead(sampleFilePath);
    var pptDoc = new Presentation(docStream);
    var pdfOptions = new PdfOptions()
    {
        SaveMetafilesAsPng = false
    };
    pdfOptions.NotesCommentsLayouting.CommentsPosition = CommentsPositions.Bottom;
    pptDoc.SlideSize.SetSize(612, 792, SlideSizeScaleType.Maximize);
    pptDoc.SlideSize.Orientation = SlideOrientation.Landscape;
    pptDoc.HeaderFooterManager.SetAllDateTimesVisibility(false);
    pptDoc.HeaderFooterManager.SetAllFootersText(string.Empty);
    pptDoc.HeaderFooterManager.SetAllHeadersVisibility(false);
    pptDoc.HeaderFooterManager.SetAllFootersVisibility(false);

    foreach (var slide in pptDoc.Slides)
    {
        slide.Hidden = false;
        var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 0, 0, pptDoc.SlideSize.Size.Width, pptDoc.SlideSize.Size.Height, false);
        shape.LineFormat.Width = 2;
        shape.LineFormat.FillFormat.FillType = FillType.Solid;
        shape.LineFormat.FillFormat.SolidFillColor.Color = Color.Black;
    }
    using (var pdfStream = new MemoryStream())
    {
        pptDoc.Save(pdfStream, SaveFormat.Pdf, pdfOptions);

        using (var filestream = File.Create($@"C:\Temp\Output\Result.pdf"))
        {
            pdfStream.Seek(0, SeekOrigin.Begin);
            pdfStream.CopyTo(filestream);
            filestream.Close();
        }
    }
}
