[mapguide-users] Trouble with rendering service

[monegodj]

This snippet is where I connect to the rendering service, call it, and then
write to the HTML response (and to file, to test the call). I've cut out
setting up the selection and the map connection (sel and map) to keep this
brief.


        ...

        MgRenderingService sRendering =
(MgRenderingService)connection.CreateService(MgServiceType.RenderingService);
        MgByteReader mapguideImageData = sRendering.RenderMap(map, sel,
"JPG");
        byte[] imageData = new byte[mapguideImageData.GetLength()];
        mapguideImageData.Read(imageData, 0);
        Response.ContentType = mapguideImageData.GetMimeType();
        Response.BinaryWrite(imageData);
        Response.End();
        FileStream f = (new
FileInfo(@"D:\test.jpg")).Open(FileMode.OpenOrCreate, FileAccess.Write);
        using(f)
        {
            foreach(byte b in imageData)
            {
                f.WriteByte(b);
            }
        }
