1，read image bmp file into memory buffer,
2, locate gEfiGraphicsOutputProtocolGuid
EFI_GUID gEfiGraphicsOutputProtocolGuid = EFI_GRAPHICS_OUTPUT_PROTOCOL_GUID;
Status = gBS->LocateProtocol(
&gEfiGraphicsOutputProtocolGuid,
NULL,
(VOID **)&m_GraphicsOutput);
3, call blt function
Status = m_GraphicsOutput->Blt(m_GraphicsOutput, (EFI_GRAPHICS_OUTPUT_BLT_PIXEL*)bitmap, EfiBltBufferToVideo, StartX, StartY, DestinationX, DestinationY, Width, Height, m_frame_width*4);
