intersection_line_contour_xldintersection_line_contour_xldIntersectionLineContourXldIntersectionLineContourXldintersection_line_contour_xld — Calculate the intersection points of a line and an XLD contour
Signature

def intersection_line_contour_xld(contour: HObject, line_row_1: Union[float, int], line_column_1: Union[float, int], line_row_2: Union[float, int], line_column_2: Union[float, int]) -> Tuple[Sequence[float], Sequence[float], int]
def intersection_line_contour_xld_s(contour: HObject, line_row_1: Union[float, int], line_column_1: Union[float, int], line_row_2: Union[float, int], line_column_2: Union[float, int]) -> Tuple[float, float, int]
Description
intersection_line_contour_xldintersection_line_contour_xldIntersectionLineContourXldIntersectionLineContourXldintersection_line_contour_xld calculates the intersection points
of a line and an XLD ContourContourContourcontourcontour. The line is defined by the points
(LineRow1LineRow1LineRow1lineRow1line_row_1,LineColumn1LineColumn1LineColumn1lineColumn1line_column_1) and
(LineRow2LineRow2LineRow2lineRow2line_row_2,LineColumn2LineColumn2LineColumn2lineColumn2line_column_2).
The intersection points, if any, are returned in
(RowRowRowrowrow,ColumnColumnColumncolumncolumn).
If a part of the XLD contour lies on the line
IsOverlappingIsOverlappingIsOverlappingisOverlappingis_overlapping returns the value 1, otherwise 0 is returned.
In this case the endpoints of the XLD segment
are returned in (RowRowRowrowrow,ColumnColumnColumncolumncolumn).
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
