Methods


Name Description
Method Accurate_ClipLineSFWithPolygon This function has 2 overloads.
MethodBlue ClipLineSFWithMultiPartPolygon This function has 4 overloads.
Method Fast_ClipLineSFWithPolygon This function has 2 overloads.
MethodBlue Fast_ProcessPartInAndOutPoints Divides a line containing both inside and outside polygon points into multiple 2pt segments. Calculates intersecetions and finds the portions of the line that are within the polygon.
Method ProcessAllInsidePoints For lines where every point lies within the polygon, this function will find if a 2pt segment crosses outside of the polygon and then adds only the internal segments to the result file.
MethodBlue ProcessAllOutsidePoints For lines where every point lies outside the polygon, this function will find if any 2pt segment crosses within the polygon and then adds the internal segments to the result file.
