Description

get_polygon_xldget_polygon_xldGetPolygonXldGetPolygonXldget_polygon_xld returns the following values of the XLD polygon PolygonPolygonPolygonpolygonpolygon:

RowRowRowrowrow Row coordinates of the polygons' points
ColColColcolcol Column coordinates of the polygons' points
LengthLengthLengthlengthlength Lengths of the line segments between points i and i+1, respectively
PhiPhiPhiphiphi Angles to the normal vectors of the line segments between points i and i+1, respectively

Execution Information

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