Fist of all I have included the swc as an external library in as3 advanced configuration. I have an image in the library with a class name Test and in frame 1 I have this code:

———————————–
//Use an image from library
var bitmap:Bitmap = new Bitmap();
var mytest:Test=new Test(200,200);
bitmap.bitmapData=mytest;

//And the Alchemy stuff
import cmodule.as3_jpeg_wrapper.CLibInit;
var as3_jpeg_wrapper:Object;
//
var quality:int=100;
var bitmapData:BitmapData;
var WIDTH:int=100;
var HEIGHT:int=100;
var imgAlchemy:Bitmap=new Bitmap();
//
// init alchemy library
var loader:CLibInit=new CLibInit ;
as3_jpeg_wrapper=loader.init();
// get image
bitmapData=bitmap.bitmapData;
//
function startAlchemy():void {
var baSource:ByteArray=bitmapData.clone().getPixels(new Rectangle(0,0,WIDTH,HEIGHT));
var baAlchmey:ByteArray=as3_jpeg_wrapper.write_jpeg_file(baSource,WIDTH,HEIGHT,3,2,quality);
imgAlchemy.bitmapData.setPixels(new Rectangle(0,0,WIDTH,HEIGHT), baAlchmey);
addChild(imgAlchemy);
}
startAlchemy();
—————————————————–
And i get this mesage from flash:

VerifyError: Error #1014: Class cmodule.as3_jpeg_wrapper::CLibInit could not be found.

at global$init()

Any ideas? Thanks in advance.

A little tip:
I found that it was very easy to get the progress of the encoding when using the asynchronous encoder. Just set up a function that monitors baSource.position/baSource.length via setInterval or similar while encoding.
