SVG_Define_marker ( parentSVGObject ; id {; x ; y {; width ; height {; orientation}}} ) -> Function result 
Parameter Type   Description
parentSVGObject  SVG_Ref in Reference of parent element
id  String in Name of symbol
Longint in Coordinate on X axis of reference point
Longint in Coordinate on Y axis of reference point
width  Longint in Width of marker
height  Longint in Height of marker
orientation  Longint in Orientation of marker
Function result  SVG_Ref in Reference of marker

The SVG_Define_marker command creates a marker in the SVG container designated by parentSVGObject and returns its reference. If parentSVGObject is not an SVG document, an error is generated.

A marker object is used to draw an arrow or multiple markers (the points of a curve for example). A marker will be attached to an SVG element with the SVG_SET_MARKER command.

The id parameter specifies the name of the marker. The name will be used to associate a marker with an object. If an element with the same name exists, it will be replaced.

The optional x and y parameters specify the coordinates of the reference point that must line up exactly with the marker position.

The optional width and height parameters specify the width and height of the rendered rectangle.

The optional orientation parameter can be used to adjust the orientation of the marker. A value included between 0 and 360 represents the angle between the X axis of the marker and that of the user space. If this parameter is omitted or if its value does not fall in the 0 - 360 interval, the placement will be calculated automatically by the rendering engine according to the object.

Example  

Refer to the example of the SVG_SET_MARKER command.
