How can I use script 2 to action script 3 by changing Image loading with preloader, Initial settings, alignment?

I have used action script 2 for flash files but since the action script 2 doesn't support by any browser, I need to change my action script 2 code to action script 3. While I was trying to convert using adobe animate, it started to show some errors in image loading with preloader, initial settings, vertical/ horizontal alignment and so on. The code and the error messages are given below:

    mcl = new MovieClipLoader();
    tempMc = content_clip.inner_clip.ImageHolder.Content.createEmptyMovieClip("temp", 1);
    mcl.loadClip(image, tempMc);
    mcl.onLoadStart = function() {
        //Image loading progress
        loader.start_(tempMc);
    };
    mcl.onLoadInit = function(mc) {
        //After loading the image:
        if (imageSmoothing and image.substr(image.lastIndexOf(".")+1) ne "swf") {
            //If imageSmoothing is set 'true' and the content is not swf, we need to capture the bitmap data
            //for better look:If imageSmoothing is set 'false' or the content is not an image (but swf), 
            //we should show the content 'as is' without bitmap capture.
            myBmp = new flash.display.BitmapData(mc._width, mc._height, true, 0x00CCCCCC);
            myBmp.draw(mc);
            removeMovieClip(mc);
