using var image = Image.Load("input.wmf");
var pngOptions = new PngOptions
{
    VectorRasterizationOptions = new WmfRasterizationOptions
    {
        BackgroundColor = Color.Transparent,

cpp
 using (var svgStream = new MemoryStream(File.ReadAllBytes("D:\\J1C.svg")))
 using (var pdfStream = new MemoryStream())
 {
