Save slide as image results in blank output


I’m trying to save slides to images with Aspose.Slides .NET and for the below attached file it results in a blank output for the 13th slide

var sld = presentation.Slides[12];
var bmp = sld.GetThumbnail(1f, 1f);
bmp.Save(output, options);

If I edit anything in the file and save then the output file for slide 13 appears as normal. Please investigate it

slide 13.zip (443.3 KB)
