{
try
{
byte[] output = new byte[buff.Width * buff.Height];
GCHandle pinnedArray = GCHandle.Alloc(output, GCHandleType.Pinned); // make
IntPtr pointer = pinnedArray.AddrOfPinnedObject();
buff.ReadRect(0, 0, buff.Width, buff.Height, pointer);
Marshal.Copy(pointer, output, 0, output.Length);
pinnedArray.Free();
return output;
