gen_contour_polygon

Herror ::gen_contour_polygon_xld ( Hobject *Contour, const HTuple &Row, const HTuple &Col ) HXLDCont HXLDCont::GenContourPolygonXld ( const HTuple &Row, const HTuple &Col )

Generate an XLD contour from a polygon (given as tuples).

::gen_contour_polygon_xld generates an XLD contour Contour from a polygon given in the tuples Row and Col. This operator is useful if contours have been obtained from routines outside the core library, but higher level operators, e.g., polygon approximation and extraction of parallels, are to be performed on the contours.

Parameters

`Contour` (output_object)	xld_cont `->` Hobject : HXLDCont*
Resulting contour.

`Row` (input_control)	number-array `->` HTuple.double / long
Row coordinates of the polygon.
Default value: '[0,1,2,2,2]'
Suggested values: 0, 1, 2, 3, 4, 5, 10, 20, 50, 100, 200, 500

`Col` (input_control)	number-array `->` HTuple.double / long
Column coordinates of the polygon.
Default value: '[0,0,0,1,2]'
Suggested values: 0, 1, 2, 3, 4, 5, 10, 20, 50, 100, 200, 500
