| Package | mx.graphics |
| Class | public class LinearGradient |
| Implements | IFill |
entries Array
to define the colors that make up the gradient fill.
In MXML, you define a LinearGradient by adding a series of GradientEntry objects, as the following example shows:
<mx:fill>
<mx:LinearGradient>
<mx:entries>
<mx:GradientEntry color="0xC5C551" ratio="0" alpha=".5"/>
<mx:GradientEntry color="0xFEFE24" ratio=".33" alpha=".5"/>
<mx:GradientEntry color="0xECEC21" ratio=".66" alpha=".5"/>
</mx:entries>
</mx:LinearGradient>
</mx:fill>
You can also define a LinearGradient as a fill for any graphic element in ActionScript, as the following example shows:
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()">
<mx:Script>
import flash.display.Graphics;
import flash.geom.Rectangle;
import mx.graphics.GradientEntry;
import mx.graphics.LinearGradient;
private function init():void {
var w:Number = 200;
var h:Number = 200;
var s:Sprite = new Sprite();
// Add the new Sprite to the display list.
rawChildren.addChild(s);
var g:Graphics = s.graphics;
g.lineStyle(1,0x33CCFF,1.0);
var fill:LinearGradient = new LinearGradient();
var g1:GradientEntry = new GradientEntry(0xFFCC66,0,.5);
var g2:GradientEntry = new GradientEntry(0x000000,.33,.5);
var g3:GradientEntry = new GradientEntry(0x99FF33,.66,.5);
fill.entries = [g1,g2,g3];
fill.angle = 240;
// Draw a box and fill it with the LinearGradient.
g.moveTo(0,0);
fill.begin(g,new Rectangle(0,0,w,h));
g.lineTo(w,0);
g.lineTo(w,h);
g.lineTo(0,h);
g.lineTo(0,0);
fill.end(g);
}
</mx:Script>
</mx:Application>

| angle | property |
angle:Number [read-write]Controls the transition direction. By default, the LinearGradient class defines a transition from left to right across the graphical element. A value of 180 causes the transition to occur from right to left.

public function begin(target:Graphics, rc:Rectangle):voidStarts the fill.
Parameterstarget:Graphics — The target Graphics object that is being filled.

rc:Rectangle — The Rectangle object that defines the size of the fill inside the
target. If the dimensions of the Rectangle are larger than the
dimensions of the target, the fill is clipped. If the dimensions
of the Rectangle are smaller than the dimensions of the target,
the fill expands to fill the entire target.
