#1
download AS3 JPEG encoder
http://code.google.com/p/as3corelib/

#2
add that encoder to your class path (e.g. to source of that lib) and write a code like:

import flash.display.*;
import flash.geom.*;
import mdm.*;
import com.adobe.images.JPGEncoder;
//
function doTest():void
{
        var shape:Shape = new Shape();
        shape.graphics.beginFill(0x00FF00);
        shape.graphics.drawRect(0, 0, 200, 200);
        shape.graphics.endFill();
        this.addChild(shape);
        var bmp:BitmapData = new BitmapData(shape.width, shape.height);
        bmp.draw(shape);
        var jpgEncoder:JPGEncoder = new JPGEncoder(85);
        var jpgStream:ByteArray = jpgEncoder.encode(bmp);
        //
        var jpgPath:String = mdm.Application.path+"myImage.jpg";
        //
        mdm.FileSystem.BinaryFile.setDataBA(jpgStream);
        mdm.FileSystem.BinaryFile.writeDataBA(jpgPath);
        /// let's open it via system
        mdm.System.exec(jpgPath);
        
};
//
mdm.Application.init(this, doTest);

(85 - is magic number - here for compression ratio/quality)

in ZINC Builder make sure you've added mdm_filesystem and mdm_system for above example to work,

это пример с форума мдм.

function snapPic():void{
    if(myMessageTxt.text.length > 0){
        var bitmapData:BitmapData = new BitmapData(pic.width, pic.height);
        bitmapData.draw(pic,new Matrix());
        var bitmap : Bitmap = new Bitmap(bitmapData);
        var jpg:JPEGEncoder = new JPEGEncoder();
        var ba:ByteArray = jpg.encode(bitmapData);
        file.save(ba,myMessageTxt.text + '.jpg');
    } else {
        Alert.show("Please enter your First name","Error");
    }
}

а это пример для 10-ого плеера, первый попавшийся в гугле по запросу "Flash Player 10 save to file".

Достаточно?
