Herror ::get_lines_xld ( Hobject Polygon, HTuple *BeginRow, HTuple *BeginCol, HTuple *EndRow, HTuple *EndCol, HTuple *Length, HTuple *Phi ) HTuple HXLDPoly::GetLinesXld ( HTuple *BeginCol, HTuple *EndRow, HTuple *EndCol, HTuple *Length, HTuple *Phi ) const HTuple HXLDPolyArray::GetLinesXld ( HTuple *BeginCol, HTuple *EndRow, HTuple *EndCol, HTuple *Length, HTuple *Phi ) const

Return an XLD polygon's data (as lines).

::get_lines_xld returns the XLD polygon Polygon as a set of lines. The following values are returned:

  BeginRow:   Row coordinates of the lines' start points
  BeginCol:   Column coordinates of the lines' start points
  EndRow:     Row coordinates of the lines' end points
  EndCol:     Column coordinates of the lines' end points
  Length:     Lengths of the line segments
  Phi:        Angles of the line segments

Parameters

`Polygon` (input_object)	xld_poly(-array) `->` Hobject: HXLDPoly(Array)
Input XLD polygons.

`BeginRow` (output_control)	line.begin.y-array `->` HTuple.double *
Row coordinates of the lines' start points.

`BeginCol` (output_control)	line.begin.x-array `->` HTuple.double *
Column coordinates of the lines' start points.

`EndRow` (output_control)	line.end.y-array `->` HTuple.double *
Column coordinates of the lines' end points.

`EndCol` (output_control)	line.end.x-array `->` HTuple.double *
Column coordinates of the lines' end points.

`Length` (output_control)	real-array `->` HTuple.double *
Lengths of the line segments.

`Phi` (output_control)	angle.rad-array `->` HTuple.double *
Angles of the line segments.
