It does support reading it but you need to tell Magick.NET the type of image you are reading. Here is an example of how you could do that:
byte[] bytes = Encoding.UTF8.GetBytes(svgStr); MagickReadSettings settings = new MagickReadSettings() { Format = MagickFormat.Svg }; using (MagickImage image = new MagickImage(bytes,settings)) { image.Write(@"C:\Snakeware.png"); }
