ISlide.ConvertToImage does not respect the Format Background Transparency Setting

When exporting a slide to EMF using ISlide.ConvertToImage with Background Transparency set to 100%, the resulting EMF file has a white non-transparent background.  When exporting the same slide using MS PowerPoint, the resulting EMF does have the expected transparent background.

Please note, setting the ISlide.Background.Fill.FillType to FillType.None results in an EMF with a white background as well.

Could you provide an example exporting a slide to an EMF with a transparent background?

Hi Russell, 

Greetings from Syncfusion, 

We were able to reproduce the issue “Transparency not preserved while converting a PowerPoint slide to EMF image” and we confirm this as a bug and logged a defect report. The fix will be available in our Service pack 1 of 2018 Volume 4 release which is scheduled to be rolled out on end of January 2019. 

We will update the status of the reported issue in the following feedback portal periodically. 

Dilli babu.
