Convert wmf to jpeg causes black background in result image.

Hi!

When i use the code below to convert a wmf to a jpg image, the output will
always be with a black backgound.

("data" is a byte array containing the WMF file)

System.IO.MemoryStream ms = new MemoryStream(data,0,data.Length);
ms.Write(data,0,data.Length);
ms.Position = 0;

System.Drawing.Image img = System.Drawing.Image.FromStream( ms );

this.Response.Clear();
this.Response.ContentType = "image/jpg";
img.Save(this.Response.OutputStream,
System.Drawing.Imaging.ImageFormat.Jpeg);

Does anyone have a solution?

Same happens to transparent gifs there is some code that does the job for
gifs maybe it works for your issue too.
I wrote an article (but its german):
