If the specified transform is non-null, returns a function that removes the delta-encoding from the specified arc and applies the specified transform. The specified arc coordinates are modified in-place, and the arc is returned. If the specified transform is null, returns the identity function.
topojson.relative(transform)
If the specified transform is non-null, returns a function that applies the delta-encoding to the specified arc and removes the specified transform. The specified arc coordinates are modified in-place, and the arc is returned. If the specified transform is null, returns the identity function.
topojson.absolute([transform])
If the specified transform is non-null, returns a function that removes the delta-encoding from the specified arc and applies the specified transform. The specified arc coordinates are modified in-place, and the arc is returned. If the specified transform is null, returns the identity function.
