Cut of a straight line with a distance. Delivers the intersection, if necessary the factors of (P2-P1) and (P4-P3) to reach of the intersection. All back values which are not needed may receive zero pointer. Parametre x1 (stands in) [IN] Co-ordinate on the x axis of the first point of the straight lines. y1 (stands in) [IN] Co-ordinate on the Y axis of the first point of the straight lines. x2 (stands in) [IN] Co-ordinate on the x axis of the second point of the straight lines. y2 (stands in) [IN] Co-ordinate on the Y axis of the second point of the straight lines. x3 (stands in) [IN] Co-ordinate on the x axis of the first point of the distance. y3 (stands in) [IN] Co-ordinate on the Y axis of the first point of the distance. x4 (stands in) [IN] Co-ordinate on the x axis of the second point of the distance. y4 (stands in) [IN] Co-ordinate on the Y axis of the second point of the distance. xs (stands in *) [IN / OUT] Co-ordinate on the x axis of the intersection. ys (stands in *) [IN / OUT] Co-ordinate on the Y axis of the intersection. s12 (stands in *) [IN / OUT] s12 is the factor with which is determined whether the intersection still lies on the straight lines. Is valid 0≤s12≤1, so the intersection is still on the straight lines. s34 (stands in *) [IN / OUT] s34 is the factor with which is determined whether the intersection still lies on the distance. Is valid 0≤s34≤1, so the intersection is still on the distance. Result (int) [OUT] M_Param_Beschr Declaration #include "basic.h"
