| Version | Published | Release Notes | Action |
|---|---|---|---|
| 1.5.0 | v1.5 Replaced selfintersection algorithm because it yielded inaccurate results; added user definable resolution parameter for drawing the circle pieces of the resulting polygon. |
||
| 1.4.0 | v1.5: Replaced selfintersection algorithm because it yielded inaccurate results; added user definable resolution parameter for drawing the circle pieces of the resulting polygon. |
||
| 1.3.0 | New and faster CW/CCW detection method for the input polygon. Old method returned incorrect results when the polygon points have negative x-values only. |
||
| 1.2.0 | Added a bunch error and warning messages for badly formed input. Automatically closes input polygon if not closed (warning generated). |
||
| 1.1.0 | Fixed bug in determining if input polygon is defined CW or CCW |
||
| 1.0.0 |
