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");
