      java.awt.image.BufferedImage readImage()
      Reads an image from the stream that was previously written with SEObjectOutputStream.writeImage(java.awt.image.BufferedImage).

        Reads an image from the stream that was previously written with SEObjectOutputStream.writeImage(java.awt.image.BufferedImage).
        Returns:
        an image in TYPE_INT_RGB or TYPE_INT_ARGB format
        Throws:
        java.io.IOException - if an I/O error occurs
