   Nullable<ImGearRationalUInt> value

Property Value

Nullable (boxed) ImageGear.Core.ImGearRationalUInt structure value.
Remarks
This property accesses the FocalLength tag. The tag specifies the actual focal length of the lens, in mm. Conversion is not made to the focal length of a 35 mm film camera.

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.
