First Things First
Before we get started, make sure to grab the ActionScript 3 Core Library. The Core Library contains several classes and utilities that make it easy to do things such as MD5 hashing, date formatting, and image encoding to name a few. Once you have the library, just drop it into your classes folder and you are ready to go. Now we can import the JPGEncoder.

import com.adobe.images.JPGEncoder;

Encoding the MovieClip
In this example, we are going to assume that our MovieClip of interest is named sketch_mc. In order to make use of the JPEGEncoder, our MovieClip needs to become a bitmap. To do this, we are going to use the BitmapData class. The contructor for this class requires two arguments: width and height. Since we want our jpeg to be the same size as sketch_mc, we use it’s width and height properties. Then by using sketch_mc as an argument, the draw method draws our MovieClip on to the bitmap.

import com.adobe.images.JPGEncoder;

var jpgSource:BitmapData = new BitmapData (sketch_mc.width, sketch_mc.height);
jpgSource.draw(sketch_mc);

Now that sketch_mc is in bitmap form, we can use the JPGEncoder. When creating a new instance of this class, you can set the level of compression by passing in a number from 1 - 100. Then to create our jpeg, we call the encode method and use our BitmapData instance as the argument. The encode method returns the jpeg in the form of a ByteArray, which is simply an AS3 class that makes working with binary data a little easier.

import com.adobe.images.JPGEncoder;

var jpgSource:BitmapData = new BitmapData (sketch_mc.width, sketch_mc.height);
jpgSource.draw(sketch_mc);

var jpgEncoder:JPGEncoder = new JPGEncoder(85);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);

From the Flash Player to the Hard Drive
ActionScript 3 has done all the work neccessary to turn our MovieClip into a jpeg, but it needs a little help in making it available to download. To make this happen, we will need to post our ByteArray to a server side script using the URLRequest class. Since we are posting binary data, we must set the content-type to “application/octet-stream”. It is also important to note that the file being downloaded will need a name, so we pass that to our server side script as a query string.

import com.adobe.images.JPGEncoder;

var jpgSource:BitmapData = new BitmapData (sketch_mc.width, sketch_mc.height);
jpgSource.draw(sketch_mc);

var jpgEncoder:JPGEncoder = new JPGEncoder(85);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);

var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream");
var jpgURLRequest:URLRequest = new URLRequest("jpg_encoder_download.php?name=sketch.jpg");
jpgURLRequest.requestHeaders.push(header);
jpgURLRequest.method = URLRequestMethod.POST;
jpgURLRequest.data = jpgStream;
navigateToURL(jpgURLRequest, "_blank");

smsx.cab을 이용한 웹페이지 프린트 설정하기


<body> 안에 아래 코드 삽입

<object id="factory" style="display:none" viewastext
 classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814"
 codebase="/include/js/smsx.cab#Version=6,3,439,30"> </object>

최신버젼은 http://www.meadroid.com/scriptx/sxdownload.asp 이곳에서 다운로드
오브젝트 안에 버젼정보 맞춰주고 다운받은 파일을 웹서버에 올리고 경로를 맞춰줌

<a href="#" onclick="printArea()">프린트 하기</a>

<script type="text/javascript">
function printArea() {
    factory.printing.header = ""; //머릿말 설정
    factory.printing.footer = ""; // 꼬릿말 설정
    factory.printing.portrait = false;  //false = 가로 출력 , true = 세로 출력 
    factory.printing.leftMargin = 0.0;   //  좌측여백
    factory.printing.topMargin = 0.0;   // 위 여백
    factory.printing.rightMargin = 0.0;  // 우측여백
    factory.printing.bottomMargin = 0.0;  // 아래여백
    factory.printing.Print(false, window); 
    //  false = 프린트 대화창안열음 , true = 대화창 열음
    //    window = 윈도우 전체 출력 , 또는 프레임명을 넣어서 프레임을 출력한다.
