Math Equations on PNG Image Are Inconsistent with Original PowerPoint Presentation

Aspose.Slides Product Family
, ,
#1

Hi,

We observed inconsistency with output from original presentation from Aspose slide .NET 21.9 to Aspose 22.8. Things were better in 21.9

Environment : Windows 10 , .NET 4 framework

Code snippet :

for (int i = 0; i < m_Presentation.Slides.Count; i++)
{
    var thumbnail = m_Presentation.Slides[i].GetThumbnail(1, 1);
    var outPath = "pathtofile" + "snapshot_slide_" + (i + 1) + ".png";
    thumbnail.Save(outPath, ImageFormat.Png);
}

Sample presentation with which this issue was observed : sample.zip (137.3 KB)

Kindly note that the issue was observed despite all the slides being simple slides
with no animations or transitions.

Regards,
Raman
