Description

The operator distance_pcdistance_pcDistancePcDistancePcdistance_pc calculates the distance between one or several points and a single contour. As input the coordinates of the points (RowRowRowrowrow,ColumnColumnColumncolumncolumn) and the contour (ContourContourContourcontourcontour) are expected. The parameters DistanceMinDistanceMinDistanceMindistanceMindistance_min and DistanceMaxDistanceMaxDistanceMaxdistanceMaxdistance_max return the result of the calculation. Note that the result corresponds to the distances between the points and the segments of the contour and not the distances between the points and the base points of the contour (see also distance_contours_xlddistance_contours_xldDistanceContoursXldDistanceContoursXlddistance_contours_xld).

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Automatically parallelized on internal data level.
