Graphics.snap_to_bitmap VX function to XP.

[MarioSuperStar]

Is there a script(already) which can take a screenshot of the game window and load it like the Graphics.snap_to_bitmap function in VX?

module Graphics

  RtlMoveMemory          = Win32API.new('kernel32', 'RtlMoveMemory', 'pii', 'i')

  BitBlt                 = Win32API.new('gdi32', 'BitBlt', 'iiiiiiiii', 'i')

  CreateCompatibleBitmap = Win32API.new('gdi32', 'CreateCompatibleBitmap', 'iii', 'i')

  CreateCompatibleDC     = Win32API.new('gdi32', 'CreateCompatibleDC', 'i', 'i')

  DeleteObject           = Win32API.new('gdi32', 'DeleteObject', 'i', 'i')

  GetDIBits              = Win32API.new('gdi32', 'GetDIBits', 'iiiiipi', 'i')

  SelectObject           = Win32API.new('gdi32', 'SelectObject', 'ii', 'i')

  SetDIBits              = Win32API.new('gdi32', 'SetDIBits', 'iiiiipi', 'i')

  hWnd = Win32API.new('user32', 'FindWindow', 'pp', 'i').call('RGSS Player', 0)

  DC   = Win32API.new('user32', 'GetDC', 'i', 'i').call(hWnd)

  def self.snap_to_bitmap

    bitmap = Bitmap.new(width=640, height=480)

    RtlMoveMemory.call(address="\0"*4, bitmap.__id__*2+16, 4)

    RtlMoveMemory.call(address, address.unpack('L')[0]+8, 4)

    RtlMoveMemory.call(address, address.unpack('L')[0]+16, 4)

    address = address.unpack('L')[0]

    info = [40,width,height,1,32,0,0,0,0,0,0].pack('LllSSLLllLL')

    hDC = CreateCompatibleDC.call(DC)

    hBM = CreateCompatibleBitmap.call(DC, width, height)

    DeleteObject.call(SelectObject.call(hDC, hBM))

    SetDIBits.call(hDC, hBM, 0, height, address, info, 0)

    BitBlt.call(hDC, 0, 0, width, height, DC, 0, 0, 0xCC0020)

    GetDIBits.call(hDC, hBM, 0, height, address, info, 0)

    DeleteObject.call(hBM)

    DeleteObject.call(hDC)

    bitmap

  end

end
