Does Aspose slide include svg into ppt slide? Is there way using slide api to do this? Any snippet would be good for reference.
I suggest you to please try using following sample code on your end using latest Aspose.slides for .NET 17.12.
string dataDir = RunExamples.GetDataDir_PresentationProperties();
using (var pres = new Presentation())
{
var svgContent = File.ReadAllText(svgPath);
var emfImage = p.Images.AddFromSvg(svgContent);
pres.Slides[0].Shapes.AddPictureFrame(ShapeType.Rectangle, 0, 0, emfImage.Width, emfImage.Height, emfImage);
pres.Save(outPptxPath, SaveFormat.Pptx);
}
