New Post: How to resize PDF converted to JPEG

I need to resize an PDF converted to a JPEG which is converted to a Base64 using the method ToBase64()

I tried the following but didn't work

Dim settings As New MagickReadSettings()
     settings.Density = New MagickGeometry(400, 400)
     settings.Width = 800
     settings.Height = 600

Using image As New MagickImage(file.InputStream, settings)
          image.Format = MagickFormat.Jpeg
          imgString = image.ToBase64()
          image.Write(Server.MapPath("../Scan/") & imgString)
End Using

The image is being saved but not in the correct size


Thanks
