Description

query_contour_attribs_xldquery_contour_attribs_xldQueryContourAttribsXldQueryContourAttribsXldquery_contour_attribs_xld returns the names of the defined attributes of an XLD contour ContourContourContourcontourcontour in AttribsAttribsAttribsattribsattribs. Attributes are additional values defined for each contour point, e.g., the direction perpendicular to the contour ('angle'"angle""angle""angle""angle"). Operators which define contour point attributes contain a description of the name and semantics of the defined values. The operator get_contour_attrib_xldget_contour_attrib_xldGetContourAttribXldGetContourAttribXldget_contour_attrib_xld can be used to access the values of a particular attribute.

For an overview of the different contour point attributes and the operators that add them to XLD contours see the operator reference of get_contour_attrib_xldget_contour_attrib_xldGetContourAttribXldGetContourAttribXldget_contour_attrib_xld.

Execution Information

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