WMF Images Are Rendered Incorrectly when Converting PPTX to PDF in C#

Hi,

When converting a PPTX to PDF using Aspose, I noticed the output layout was rendered incorrectly.

Code:

        var doc = new Presentation(@".\test.pptx");
        var saveOptions = new PdfOptions
        {
            Compliance = Aspose.Slides.Export.PdfCompliance.Pdf15,
            SaveMetafilesAsPng = false
        };            
        doc.Save(@".\out.pdf", SaveFormat.Pdf, saveOptions);

If I save the PPTX manually to PDF using MS Office ‘save as’ feature, the issue doesn’t happen.

I’ve attached my test files, font files and a screenshot for your reference. Could you please take a look?
