CPLYiClipLineInt Method

Clips a line in or out of the polygons for intersections (<define>GS_DOUBLE</define>). Intersections are returned as fiducials down the line stored in VV starting at the first point of the line. Examples: No intersection: <define>PLY_LINE_CLIP_OUTSIDE</define>, 0 intersections Starts outside, ends inside: <define>PLY_LINE_CLIP_OUTSIDE</define>, 1 intersection Starts outside, intersects then ends inside or outside: <define>PLY_LINE_CLIP_OUTSIDE</define>, 2 intersections Starts inside, ends inside : <define>PLY_LINE_CLIP_INSIDE</define>, 1 intersection (gives end-of-line) Starts inside, ends outside : <define>PLY_LINE_CLIP_INSIDE</define>, 1 intersection
