Used to draw points and multipoints (or nodes of polylines and polygons) on the graphics layer using simple markers. SimpleMarkerSymbol is used to display points as a simple shape, for example, a circle. In addition, the symbol can have an optional outline, which is defined by a line symbol.

Example
MXML usages of SimpleMarkerSymbol: 
 <esri:SimpleMarkerSymbol id="smsDefault"/>
 <esri:SimpleMarkerSymbol id="smsBigRedSquare" size="18"

ActionScript usage of SimpleMarkerSymbol: 
 var myPointSymbol:SimpleMarkerSymbol = new SimpleMarkerSymbol(
     SimpleMarkerSymbol.STYLE_CIRCLE, 10, 0xFF0000, 0.5

Constructor detail
SimpleMarkerSymbol()constructor
public function SimpleMarkerSymbol(style:String, size:Number = 15, color:Number = 0x000000, alpha:Number = 1, xoffset:Number = 0, yoffset:Number = 0, angle:Number = 0, outline:SimpleLineSymbol = null)

Creates a new SimpleMarkerSymbol. Note that 'xoffset', 'yoffset' and 'angle' were added to the constructor in version 1.2, which changed the placement of the 'outline' parameter.

Parameters
style:String — The marker style.
 
size:Number (default = 15) — The marker size in pixels.
 
color:Number (default = 0x000000) — The marker fill color in RGB.
 
alpha:Number (default = 1) — The transparency value.
 
xoffset:Number (default = 0) — The offset on the x-axis in pixels [added to constructor in version 1.2].
 
yoffset:Number (default = 0) — The offset on the y-axis in pixels [added to constructor in version 1.2].
 
angle:Number (default = 0) — The angle of the marker [added to constructor in version 1.2].
 
outline:SimpleLineSymbol (default = null) — The marker outline.
