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);
        }

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