@mitesh.prajapati In your case you can use SVG image to insert a circle. For example, like this:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" width="28.813" height="28.813">
<g>
<circle fill="#E83816" stroke="#E61E19" cx="14.406" cy="14.406" r="13.906"/>
</g>
</svg>
You can use this SVG in your HTML, Aspose.Words will insert it as a shape:
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertHtml("<svg xmlns=\"http://www.w3.org/2000/svg\" xmlns:xlink=\"http://www.w3.org/1999/xlink\" version=\"1.1\" width=\"28.813\" height=\"28.813\"><g><circle fill=\"#E83816\" stroke=\"#E61E19\" cx=\"14.406\" cy=\"14.406\" r=\"13.906\"/></g></svg>");
doc.Save(@"C:\Temp\out.docx");
The above code produces the following output: out.docx (8.4 KB)
