Description

contour_point_num_xldcontour_point_num_xldContourPointNumXldContourPointNumXldcontour_point_num_xld returns the length of the input contour ContourContourContourcontourcontour, i.e., its number of points, in LengthLengthLengthlengthlength.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
