Thanks for your inquiry. The SVG is imported as Shape node into Aspose.Words DOM and you can export the shape node to image using following code example.
Document doc = new Document(MyDir + "in.html");
int i = 1;
foreach (Shape shape in doc.GetChildNodes(NodeType.Shape, true))
shape.GetShapeRenderer().Save(MyDir + "Out"+i+".png", new ImageSaveOptions(SaveFormat.Png));
This issue (WORDSNET-11629) is related to your input document. The Svg is not imported correctly into Aspose.Words DOM. The above code example does not export the svg to png correctly. We will update you via this forum thread once this issue is resolved. We apologize for your inconvenience.
