Transparency of graphics

TimWitt2

Hey everybody,

Is there a way to change the transparency of a particular graphic or is this only possible for a graphic layer?

Hi Tim,

If the graphics is already created, you can use the setSymbol method to do this. Ex:

var symbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID,
        new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,
        new Color([255,0,0]), 2),new Color([255,255,0,0.25])
        )

map.graphics.graphics[2].setSymbol(symbol);

According to the documentation, the transparency option is only available for RGB colors

One more question, how does this work if my color is in Hex string?

You can change the transparency of the color you assign different graphics.

var trans = Math.random();

// lineSymbol used for freehand polyline, polyline and line.
var lineSymbol = new CartographicLineSymbol(
  CartographicLineSymbol.STYLE_SOLID,
  new Color([255, 0, 0, trans]), 10,
  CartographicLineSymbol.CAP_ROUND,
  CartographicLineSymbol.JOIN_MITER, 5
);
