get_polygon

get_polygon_xld ( Polygon : : : Row, Col, Length, Phi )

Return an XLD polygon's data.

get_polygon_xld returns the following values of the XLD polygon Polygon:

  Row:     Row coordinates of the polygons' points
  Col:     Column coordinates of the polygons' points
  Length:  Lengths of the line segments between points i and i+1, respectively
  Phi:     Angles of the line segments between points i und i+1, respectively

Parameters

`Polygon` (input_object)	xld_poly `->` object
Input XLD polygon.

`Row` (output_control)	point.y-array `->` real
Row coordinates of the polygons' points.

`Col` (output_control)	point.x-array `->` real
Column coordinates of the polygons' points.

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

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