Description
The SVG_New_polygon_by_arrays command draws a closed form consisting of a set of straight connected segments in the SVG container designated by parentSVGObject and returns its reference. If parentSVGObject is not an SVG document, an error is generated.
All the coordinate values are in the user coordinate system.
The optional foregroundColor and backgroundColor parameters contain, respectively, the name of the line color and of the background color. (For more information about colors, please refer to the commands of the Colors and Gradients theme).
The optional strokeWidth parameter contains the size of the pen expressed in pixels. Its default value is 1.
