Property Value
Nullable (boxed) ImageGear.Core.ImGearRationalUInt structure value.This property accesses the SubjectDistance tag. The tag specifies the distance to the subject, given in meters. Note that if the numerator of the recorded value is FFFFFFFF.H, Infinity shall be indicated; and if the numerator is 0, Distance unknown shall be indicated.
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.
