Emoji Skin Colour Is Not Generated when Converting PPTX to PNG

Issue : PPT Slide emoji skin colour not generated.

Attaching a sample presentation with emoji to reproduce the behaviour:
The generated image from code below sample.zip (28.8 KB)
is in greyscale

		var presentation = new Presentation(szPptxPath);
		for (int i = 0; i < presentation.Slides.Count; i++)
			var thumbnail = presentation.Slides[i].GetThumbnail(1, 1);
			var imgSavePath = "./input/sample_slide_" + (i + 1) + ".png";
			thumbnail.Save(imgSavePath, ImageFormat.Png);


Thank you for reporting the issue.

I’ve reproduced the problem with the emoji colors when converting the presentation slide to PNG file and added a ticket with ID SLIDESNET-43207 to our issue tracking system. Our development team will investigate this case. We will inform you of any progress.

Please note that PowerPoint for Office 365 also doesn’t generate the emoji colors.
