GM_IDENTICAL_PTS
Start- and endpoint of the line are
identical. Calculation is not
possible.
Example Calculate the intersection points between the line and the circle.

5.6.15 GM_CalcIntersectionLineLine
Description Calculation of intersection-point line - line.
Declaration
GM_CalcIntersectionLineLine(
FirstLine AS GM_Line_Type,
SecondLine AS GM_Line_Type,
Intersection AS GM_Point_Type,
iReturnCode
AS Integer )
Remarks This function is calculating the intersection-point between two
Lines. The lines could show a transverse displacement and can be
defined as a result from 2 points, or as result from one point and
azimuth (see predefined type
GM_Line
).
Note Used formula: see Appendix, Geodesy Math. Formulas.
