SVG_New_polyline


SVG_New_polyline ( parentSVGObject {; points {; foregroundColor {; backgroundColor {; strokeWidth}}}} ) -> Function result

Parameter	Type	Description
parentSVGObject	SVG_Ref	Reference of parent element
points	String	Path
foregroundColor	String	Color or gradient name
backgroundColor	String	Color or gradient name
strokeWidth	Real	Line thickness
Function result	SVG_Ref	Reference of line

Description

The SVG_New_polyline command creates a new open broken line in the SVG container designated by parentSVGObject and returns its reference. If parentSVGObject is not a valid reference, an error is generated.

The optional points parameter can be used to pass the path points of the line as expected by the SVG standard. If this parameter is omitted or empty, the points may be set with the SVG_ADD_POINT command.

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 two triangles:

 $polyline:=SVG_New_polyline($svg;"10,10 200,100 10,100 10,10";"blue";"blue:50")

 $polyline:=SVG_New_polyline($svg;"";"red";"red:50")

 SVG_ADD_POINT($polyline;205;15)

 SVG_ADD_POINT($polyline;15;105)

 SVG_ADD_POINT($polyline;205;105)

 SVG_ADD_POINT($polyline;205;15)
