Property Value
Nullable (boxed) ImageGear.Core.ImGearRationalUInt structure value.This property accesses the GPSAltitude tag. The tag indicates the altitude based on the reference in AltitudeReference. Altitude is expressed as one RATIONAL value. The reference unit is meters.
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.
ImageGear ignores the value of this tag during image saving, and saves a value that corresponds to the saved image DIB's parameters.
See the EXIF 2.2 specification for tag usage details.
