SVG_New_polyline_by_arrays 


 

SVG_New_polyline_by_arrays ( parentSVGObject ; xArrayPointer ; yArrayPointer {; foregroundColor {; backgroundColor {; strokeWidth}}} ) -> Function result 
Parameter Type   Description
parentSVGObject  SVG_Ref in Reference of parent element
xArrayPointer  Pointer in Coordinates on X axis of points
yArrayPointer  Pointer in Coordinates on Y axis of points
foregroundColor  String in Color or gradient name
backgroundColor  String in Color or gradient name
strokeWidth  Real in Line thickness
Function result  SVG_Ref in Reference of line

The SVG_New_polyline_by_arrays command draws a broken line composed of straight segments connected together in the SVG container designated by parentSVGObject and returns its reference. If parentSVGObject is not an SVG document, an error is generated.

Usually, 'polyline' elements design open forms but they can be used for closed forms as well. In this case the last point must be set as equal to the first.

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.

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

 ARRAY LONGINT($tX;0)
 ARRAY LONGINT($tY;0)
 
 APPEND TO ARRAY($tX;10)
 APPEND TO ARRAY($tY;10)
 APPEND TO ARRAY($tX;200)
 APPEND TO ARRAY($tY;100)
 APPEND TO ARRAY($tX;10)
 APPEND TO ARRAY($tY;100)
 APPEND TO ARRAY($tX;10)
 APPEND TO ARRAY($tY;10)
 
 svgRef:=SVG_New
 objectRef:=SVG_New_polyline_by_arrays(svgRef;->$tX;->$tY)

Draw a line diagram:

 ARRAY LONGINT($tX;0)
 ARRAY LONGINT($tY;0)
  `X axis
 For($Lon_i;0;200;20)
    APPEND TO ARRAY($tX;$Lon_i)
 End for
  `Values
 APPEND TO ARRAY($tY;100)
 APPEND TO ARRAY($tY;100)
 APPEND TO ARRAY($tY;30)
 APPEND TO ARRAY($tY;30)
 APPEND TO ARRAY($tY;80)
 APPEND TO ARRAY($tY;60)
 APPEND TO ARRAY($tY;10)
 APPEND TO ARRAY($tY;40)
 APPEND TO ARRAY($tY;50)
 APPEND TO ARRAY($tY;70)
 
 objectRef:=SVG_New_polyline_by_arrays(svgRef;->$tX;->$tY;"crimson";"none";5)
