Simple Example to show how to use perlinNoise in Flash ActionScript

In the below example the stage is divided into two parts with two different effects

example

import flash.display.*;
import flash.events.Event;
import flash.geom.Point;

var _bitmap1:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight/2, true, 0xCCCCCC);
var _bitmap2:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight/2, true, 0xCCCCCC);

function perlinNoise() {
addChild(new Bitmap(_bitmap1));
_bitmap1.perlinNoise(10, 10, 2, 50, false, true,1, true);

var b:Bitmap = new Bitmap(_bitmap2);
b.y = stage.stageHeight/2;
addChild(b)
}

perlinNoise();

var t:Timer = new Timer(50)
t.addEventListener(TimerEvent.TIMER , onTimer);
var Size = 0;
var xPos = 0;
var yPos = 0;
function onTimer (e:TimerEvent) {
var point:Point=new Point(++xPos,++yPos);
_bitmap1.perlinNoise(10, 10, 2, 50, false, true,1, true, [point, point]);
++Size;
_bitmap2.perlinNoise(Size,Size, 2, 50, false, true,1, true, [point, point]);
if(Size > 50){
Size = 0;
}
}

t.start();

Working on color wheel i hope it looks good.

Recently started making a color picker which is similar to photoshop color picker

background image for AIR application

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication name="WindowedApplication_backgroundImage_test"
        xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" verticalAlign="middle">

    <mx:Style>
        WindowedApplication {
            backgroundColor: white;
            backgroundImage: ClassReference("mx.skins.halo.ApplicationBackground");
        }
    </mx:Style>

</mx:WindowedApplication>

The below code shows how to use the class

import druva.emailValidator;

trace('druva.flash@gmail.com > '+emailValidator.isValidEmail('druva.flash@gmail.com'));
// true
trace('druva.flash@gmail > '+emailValidator.isValidEmail('druva.flash@gmail'));
// false
trace('druva.@.com > '+emailValidator.isValidEmail('druva.@.com'));
//false
trace('druva.@gmail.com > '+emailValidator.isValidEmail('druva.@gmail.com'));
//true
trace('.aa@gmailcom > '+emailValidator.isValidEmail('.aa@gmailcom'));
//false

This is the actual class for validation

package druva {
  import flash.display.Sprite;

  public class emailValidator extends Sprite{
    public function emailValidator(){
    }

	public static function isValidEmail(email:String):Boolean {
		var emailExpression:RegExp = /^[a-z][\w.-]+@\w[\w.-]+\.[\w.-]*[a-z][a-z]$/i;
		return emailExpression.test(email);
	}

This examples shows how to remove white spaces from the string

 public function removeSpaces(str:String):String {
 if (str == null) { return ''; }
 return str.replace(/\s+/g, '');
 }

This is the complete flex example

<?xml version="1.0" encoding="utf-8"?>
<mx:Application
 xmlns:mx="http://www.adobe.com/2006/mxml"
 layout="absolute">
 <mx:Script>
 <![CDATA[

 public function removeSpaces(str:String):String {
 if (str == null) { return ''; }
 return str.replace(/\s+/g, '');
 }
 public function on_trim_button():void {
 reultText.text = removeSpaces(originalText.text);
 }
 ]]>
 </mx:Script>
 <mx:Button x="74" y="101" label="Trim Spaces" click="on_trim_button()"/>
 <mx:TextArea x="74" y="42" id="originalText" />
 <mx:TextArea x="74" y="157" id="reultText" />
 <mx:Label x="74" y="16" text="Enter Text" width="160"/>
 <mx:Label x="74" y="131" text="Enter Text" width="160"/>
</mx:Application>

Representational State Transfer(REST), This is a method that can identify by a URI.

IT supports HTTP methods GET, POST, PUT, DELETE, HEAD and OPTIONS.

It is possible to do everything that you can do with RPC web service with REST.

Problem with flash and REST is Flash support only GET and POST

This examples shows how to control accordion header text color

here is the complete example in flex –

<?xml version="1.0" encoding="utf-8"?>
<mx:Application
 xmlns:mx="http://www.adobe.com/2006/mxml"

 height="600"
 >

 <mx:Script>
 <![CDATA[
 public function setColors():void {
 myAcc.getHeaderAt(0).setStyle('color', 0xFF0000);
 myAcc.getHeaderAt(1).setStyle('color', 0x00FF00);
 myAcc.getHeaderAt(2).setStyle('color', 0x0000FF);
 }
 ]]>
 </mx:Script>

 <mx:Accordion id="myAcc" width="300" height="300" creationComplete="setColors()">
 <mx:VBox label="Container 1">
 <mx:Text text="123456"/>
 </mx:VBox>

 <mx:VBox label="Container 2">
 <mx:Text text="123456890"/>
 </mx:VBox>

 <mx:VBox label="Container 3">
