The program below demostrates how to capture an image of the stage and save it as a jpg image. We have drawn a yellow circle give the image capture something more interesting to render. To save the jpg image, just left-click the box above and select a location to save the image in.
The program for this jpg image capture is shown below. Additionally, you will need the JPGEncoder file which you can get here: https://github.com/mikechambers/as3corelib. To use the source file, select Edit->Preferences->Actionscript->Actionscript 3.0 Settings . . . and add the folder where you put “mikechambers-as3corelib-release.93-8-g24c6c16\mikechambers-as3corelib-24c6c16\src” to the src paths. Then you should be able to compile and execute the Actionscript code.
In this program, we import the JPGEncoder class and then draw a filled yellow circle on the stage. Next, we register an event listener to call the function SaveJPG() to save the image when a left-click occurs; Actionscript requires that file-saving code be contained in a user-initiated function.
Inside the callback, we create a BitmapData object that is the size of our stage and draw the stage into it. Then we create the encoder and call encode() to put the jpg data into a ByteArray. Finally, we create a FileReference object and save the jpg data.
import com.adobe.images.JPGEncoder; // Draw a circle on the staqe graphics.beginFill(0xFFFF00); graphics.drawCircle(160, 120, 100); graphics.endFill(); stage.addEventListener(MouseEvent.CLICK, SaveJPG); function SaveJPG(e:MouseEvent):void { // Store the image capture of stage in a BitmapData Object var qImageData:BitmapData = new BitmapData(320, 240); qImageData.draw(stage); // Set the encoding to high-quality var qEncoder:JPGEncoder = new JPGEncoder(100); var qBytes:ByteArray = qEncoder.encode(qImageData); var qFile:FileReference = new FileReference(); qFile.save(qBytes, "YellowCircle.jpg"); }

I’ve been searching for this for weeks! Thank you so much!
I’m actually working on a Cake Designer app, and downloading the final design to be downloaded as JPEG.
Will be posting the progress soon on my website: thetotobox dot com. Cheers!
The source files have since changed! idk what to do ahhhhhhhh
This is very cool. Is there any way to have the JPG save to the server in addition to saving on the hard-drive?
