abs(distance)
. Mathematically-exact buffer area boundaries can contain circular arcs. To represent these arcs using linear geometry they must be approximated with line segments. The buffer geometry is constructed using 8 segments per quadrant to approximate the circular arcs. The end cap style is CAP_ROUND.
The buffer operation always returns a polygonal result. The negative or zero-distance buffer of lines and points is always an empty {@link Polygon}. This is also the result for the buffers of degenerate (zero-area) polygons. @param distance the width of the buffer (may be positive, negative or 0) @return a polygonal geometry representing the buffer region (which may beempty) @throws TopologyException if a robustness error occurs @see #buffer(double,int) @see #buffer(double,int,int)
NOTE: The returned buffer may be larger than the valid {@link #length()}.
