SVG_New_polygon_by_arrays ( parentSVGObject ; xArrayPointer ; yArrayPointer {; foregroundColor {; backgroundColor {; strokeWidth}}} ) -> Function result

Parameter	Type	Description
parentSVGObject	SVG_Ref	Reference of parent element
xArrayPointer	Pointer	Coordinates on X axis of points
yArrayPointer	Pointer	Coordinates on Y axis of points
foregroundColor	String	Color or gradient name
backgroundColor	String	Color or gradient name
strokeWidth	Real	Line thickness
Function result	SVG_Ref	Reference of polygon

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.

Example

Draw a star (default border color and line thickness):
