Structs
The following structs are available globally.
-
Defines the No Fly Zone Data structure.
See moreDeclaration
Objective-C
struct {}
-
Aircraft attitude. The attitude of the aircraft is made up of the pitch, roll, and yaw.

Remote Controller’s Remote Focus State
The focus product has one dial (focus control) that controls two separate parts of the camera: focal length and aperture. However it can only control one of these at any one time and is an absolute dial, meaning that a specific rotational position of the dial corresponds to a specific focal length or aperture.
This means that whenever the dial control mode is changed, the dial first has to be reset to the new mode’s previous dial position before the dial can be used to adjust the setting of the new mode.
Example workflow:
- Use dial to set an Aperture of f2.2
- Change dial control mode to focal length (set
DJIRCRemoteFocusControlType) - Use the dial to change the focal length
- Change dial control mode back to aperture
- set
DJIRCRemoteFocusControlType isFocusControlWorkswill now be NO
- set
- Adjust dial back to f2.2
DJIRCRemoteFocusControlDirectionis the direction the dial should be rotatedisFocusControlWorkswill become YES when set back to f2.2
- Now the dial can be used to adjust the aperture.

AEB continuous capture parameter values.

struct {}
-
Sets the number of pictures, and sets the time interval between pictures for the Interval shoot photo mode.

Objective-C
struct {}
-
This class contains current values for some camera parameters related to exposure, which determines how sensitive the picture is to light and depends on the balance of the ISO value, the shutter speed, and the aperture value. When the camera is in different exposure modes, different parameters are automatically changed by the camera to either get the correct exposure (in Program, Shutter Priority and Aperture Priority modes), or report back the current exposure (in Manual mode). The current values of these parameters used by the camera are contained in this class.

Thermal cameras measure the apparent surface temperature of a given object. This is done by taking the amount of infrared radiation an object emits and calculating the surface temperature by applying a formula that adjusts for external factors.
This struct includes all of the external scene parameters that the thermal camera firmware allows to be customized. There are two types of parameters, optical parameters which specify how much infrared radiation is transmitted from the surface to the thermal sensor, as well as parameters that specify sources of thermal radiance other than the object.
For a more in-depth overview of the physics behind thermal imaging, see https://en.wikipedia.org/wiki/Thermography.
