I read the introduction of the library and it only supports polygon offsetting? Can this library support arc or circle offsetting?

1.I read the introduction of the library. Does it only support polygon offsetting? Can this library support arc or circle offsetting?
2.If it does not support arc or circle offsetting, can I split the arc or circle into countless small line segments and then calculate the offsetting?
