Initializes a structure to be used for pipeline clipping of a polyline or polygon to a rectangle.

geoc_clip_add_point ()

void                geoc_clip_add_point                 (GeocClip *clip,
                                                         double x,

Add an additional point to the shape to be clipped. Call this routine until all points are added.

geoc_clip_finish ()

void                geoc_clip_finish                    (GeocClip *clip);

Tells the clipping algorithm that we are at the end of the pipeline. That is, all points have been added.

geoc_clip_free ()

void                geoc_clip_free                      (GeocClip *clip);

Use this to free the filled GeocClip structure.
