I used WriteableBitmap to take the screenshot of the Image and convert that into Base64 string using FJCore. Due to Domain Issues with WriteableBitmap I am not able to read Pixels from WriteableBitmap.
getting the following Security error:
"WriteableBitmap has protected content. Pixel access is not allowed."
Method Used to convert WritableBitmap to base64string:
 public static string ConvertImagetoString(WriteableBitmap bitmap)
 {
 
 int width = bitmap.PixelWidth;
 int height = bitmap.PixelHeight;
 int bands = 3;
 byte[][,] raster = new byte[bands][,];
 for (int i = 0; i < bands; i++)
 {
 raster = new byte[width, height];
 }
 int[] bitpixes = bitmap.Pixels.ToArray();
 for (int row = 0; row < height; row++)
 {
 for (int column = 0; column < width; column++)
 {
 int pixel = bitpixes[width * row + column];
 raster[0][column, row] = (byte)(pixel >> 16);
 raster[1][column, row] = (byte)(pixel >> 8);
 raster[2][column, row] = (byte)pixel;
 }
 }
 
 ColorModel model = new ColorModel { colorspace = FluxJpeg.Core.ColorSpace.RGB };
 FluxJpeg.Core.Image img = new FluxJpeg.Core.Image(model, raster);
 MemoryStream stream = new MemoryStream();
 JpegEncoder encoder = new JpegEncoder(img, 90, stream);
 encoder.Encode(); 
 stream.Seek(0, SeekOrigin.Begin);
 byte[] binaryData = new Byte[stream.Length];
 long bytesRead = stream.Read(binaryData, 0, (int)stream.Length);
 string base64String = System.Convert.ToBase64String(binaryData, 0, binaryData.Length);
 return base64String;
 }
Function call:
 WriteableBitmap redlinescreenshot = new WriteableBitmap(this.TheMap, new TranslateTransform());
 string base64String = ConvertImagetoString(redlinescreenshot);
Any help Appreciated...Urgent!!!! Thanks
