Generate values for ROS1 sensor_msgs/Image.msg.

Be aware that the element count of the “data” field value is not generated dependent on steps and rows right now. Configuration of field “data” element size requires attention to avoid exceptions raised in underlying hypothesis functionality.

  • height (hypothesis_ros.message_fields.uint32()) – Strategy to generate height value. (Default: Default hypothesis_ros strategy.)
  • width (hypothesis_ros.message_fields.uint32()) – Strategy to generate width value. (Default: Default hypothesis_ros strategy.)
  • encoding (hypothesis.sampled_from()) – Strategy to generate encoding value. For possible values refer to include/sensor_msgs/image_encodings.h . (Default: hypothesis strategy with reasonable configuration.)
  • is_bigendian (hypothesis_ros.message_fields.uint8()) – Strategy to generate bigendian value. (Default: Default hypothesis_ros strategy.)
  • data (hypothesis_ros.message_fields.array(elements=uint8())) – Strategy to generate matrix data values. Size is steps x rows. (Default: hypothesis_ros strategy with reasonable configuration.)

  • orientation_covariance (hypothesis_ros.message_fields.array()) – Strategy to generate orientation_covariance value. (Default: Customized to 9 elements of type float64().)
  • angular_velocity (hypothesis_ros.messages.geometry_msgs.vector3()) – Strategy to generate angular_velocity value. (Default: Default hypothesis_ros strategy.)
  • angular_velocity_covariance (hypothesis_ros.message_fields.array()) – Strategy to generate angular_velocity_covariance value. (Default: Customized to 9 elements of type float64().)
  • linear_acceleration (hypothesis_ros.messages.geometry_msgs.vector3()) – Strategy to generate linear_acceleration value. (Default: Default hypothesis_ros strategy.)
  • linear_acceleration_covariance (hypothesis_ros.messages.message_fields.array()) – Strategy to generate linear_acceleration_covariance value. (Default: Customized to 9 elements of type float64().)
