com.vividsolutions.jts.operation.buffer.OffsetCurveBuilder
Computes the raw offset curve for a single {@link Geometry} component (ring, line or point).A raw offset curve line is not noded - it may contain self-intersections (and usually will). The final buffer polygon is computed by forming a topological graph of all the noded raw curves and tracing outside contours. The points in the raw curve are rounded to the required precision model. @version 1.7
