<p>The Closing Segment Factor controls how long "closing
|
|
segments" are. Closing segments are added at the middle of inside corners to ensure a smoother boundary for the buffer offset curve. In some cases (particularly for round joins with default-or-better quantization) the closing segments can be made quite short. This substantially improves performance (due to fewer intersections being created).</p>
|
|
<p>A closingSegFactor of 0 results in lines to the corner vertex. A closingSegFactor of 1 results in lines halfway to the corner vertex. A closingSegFactor of 80 results in lines 1/81 of the way to the corner vertex (this option is reasonable for the very common default situation of round joins and quadrantSegs >= 8).</p>
