def rospy_message_converter.message_converter.convert_dictionary_to_ros_message	(	message_type,
		dictionary,
		kind = `'message'`
	)

Takes in the message type and a Python dictionary and returns a ROS message.

Example:
    message_type = "std_msgs/String"
    dict_message = { "data": "Hello, Robot" }
    ros_message = convert_dictionary_to_ros_message(message_type, dict_message)

    message_type = "std_srvs/SetBool"
    dict_message = { "data": True }
    kind = "request"
    ros_message = convert_dictionary_to_ros_message(message_type, dict_message, kind)

def rospy_message_converter.message_converter.convert_ros_message_to_dictionary ( message )

Takes in a ROS message and returns a Python dictionary.

Example:
    ros_message = std_msgs.msg.String(data="Hello, Robot")
    dict_message = convert_ros_message_to_dictionary(ros_message)

def rospy_message_converter.message_converter.is_ros_binary_type	(	field_type,
		field_value
	)

Checks if the field is a binary array one, fixed size or not

is_ros_binary_type("uint8", 42)
>>> False
is_ros_binary_type("uint8[]", [42, 18])
>>> True
is_ros_binary_type("uint8[3]", [42, 18, 21]
>>> True
is_ros_binary_type("char", 42)
>>> False
is_ros_binary_type("char[]", [42, 18])
>>> True
is_ros_binary_type("char[3]", [42, 18, 21]
>>> True
