描述
intersection_line_contour_xldintersection_line_contour_xldIntersectionLineContourXldIntersectionLineContourXldIntersectionLineContourXldintersection_line_contour_xld calculates the intersection points
of a line and an XLD ContourContourContourContourcontourcontour. The line is defined by the points
(LineRow1LineRow1LineRow1LineRow1lineRow1line_row_1,LineColumn1LineColumn1LineColumn1LineColumn1lineColumn1line_column_1) and
(LineRow2LineRow2LineRow2LineRow2lineRow2line_row_2,LineColumn2LineColumn2LineColumn2LineColumn2lineColumn2line_column_2).
The intersection points, if any, are returned in
(RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn).
If a part of the XLD contour lies on the line
IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlappingis_overlapping returns the value 1, otherwise 0 is returned.
In this case the endpoints of the XLD segment
are returned in (RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn).
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
