This class uses the Liang-Biarsky parametric line-clipping algorithm as described in: Computer Graphics: principles and practice, 2nd ed., James D.
Foley et al., Section 3.12.4 on page 117. @descr The intersection between an open polygon and a rectangle is calculated and the resulting lines are placed into the poly-polygon aResult.
- Parameters
-
| rPolygon | The polygon is required to be open, ie. its start and end point have different coordinates and that it is continuous, ie. has no holes. |
| rRectangle | The clipping area. |
| aResult | The resulting lines that are the parts of the given polygon lying inside the clipping area are stored into aResult whose prior content is deleted first. |
