Aspose.Slides inverts images when rendering slides to Graphics

Slide 6 (and several others) in this file have images that are inverted when exported to to a Bitmap.
public virtual Bitmap ExportSlideAsImage(int slideNumber, Size size)

        int slideNumberToExport = slideNumber - 1 < 0 ? 0 : slideNumber;
        ISlide slide = _presentation.Slides[slideNumberToExport];
        Bitmap newImage = new Bitmap(size.Width, size.Height);
        using (Graphics graphics = Graphics.FromImage(newImage))
            slide.RenderToGraphics(new RenderingOptions(), graphics, size);

newImage.Save($“C:\temp\aspose_testing\{slideNumberToExport}.png”, ImageFormat.Png);
return newImage;

Here is another example of objects that get inverted.test2.zip (25.7 KB)

Thank you for the additional presentation example. I attached it to the issue.

Any updates?

The problem you described has been resolved. A fix will be included in Aspose.Slides 21.9 (in the second half of September).
