Property Value
ImageGear.Core.ImGearRationalUInt structure array.This property accesses the GPSDestLongitude tag. The tag indicates the longitude of the destination point. The longitude is expressed as three RATIONAL values giving the degrees, minutes, and seconds, respectively. If longitude is expressed as degrees, minutes, and seconds, a typical format would be ddd/1,mm/1,ss/1. When degrees and minutes are used and, for example, fractions of minutes are given up to two decimal places, the format would be ddd/1,mmmm/100,0/1.
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.
