'Usage
 
Dim instance As ImGearEXIFGPSMetadata
Dim value As Nullable(Of ImGearEXIFGPSAltitudeReference)
 
instance.AltitudeReference = value
 
value = instance.AltitudeReference
public Nullable<ImGearEXIFGPSAltitudeReference> AltitudeReference {get; set;}
public: __property Nullable<ImGearEXIFGPSAltitudeReference> get_AltitudeReference();
public: __property void set_AltitudeReference( 
   Nullable<ImGearEXIFGPSAltitudeReference> value
);

   Nullable<ImGearEXIFGPSAltitudeReference> get();
   void set (    Nullable<ImGearEXIFGPSAltitudeReference> value);
}

Property Value

Nullable (boxed) ImGearEXIFGPSAltitudeReference enumeration value.
Remarks
This property accesses the GPSAltitudeRef tag. The tag indicates the altitude used as the reference altitude. If the reference is sea level and the altitude is above sea level, 0 is given. If the altitude is below sea level, a value of 1 is given and the altitude is indicated as an absolute value in the GPSAltitude tag.

Get accessor returns the tag value if the tag is present in the metadata tree, or null otherwise.

Set accessor replaces the current tag value if the tag is present in the metadata tree; adds the tag if it was not present, or deletes the tag if a null value is passed.

See the EXIF 2.2 specification for tag usage details.
