Transparent Image looses transparency while converting PPTX to PDF using Aspose.Slides for Java

Dear Aspose Team,

I have a pptx slide with an image on it which is made semi-transparent by Color --> New Coloring --> Transparent. When I save the pptx file as pdf, the transparency is lost and the image is rendered as original image without the transparency filter.

Presentation p = new Presentation("data/input/" + inFile);
	String pdfFile = "data/output/pdf/" + inFile.substring(0, inFile.lastIndexOf(".")) + ".pdf";
	p.save(pdfFile, SaveFormat.Pdf);

faded-test.pptx.zip (176.9 KB)

How can I save the pptx file as pdf without loosing the transparency filter?
Would be happy about any hints!

Best regards,
