        binaryContent - Byte stream, that presumably contains a GIF image
        Returns:
        True if specified stream contains valid GIF image, false otherwise
      • isValid

        public static boolean isValid(String contentInBase64)

        Checks whether specified base64-encoded string is a valid GIF image

        Parameters:
        contentInBase64 - Content of the presumably GIF image in a form of base64-encoded string
        Returns:
