DataMix

Version 1.0.0.1
DataMix is a fundamental component allows to convert from MovieClip to Animal Bitmap, DataMix store the BitmapData's after analysis & processing from MovieClip with methods basic: width, hight, total BitmapData.

The constructor:

/**
* In special cases, we only get the size, no need to get data
* @param mc as MovieClip with multiple frames
*/
public function DataMix(mc:MovieClip)

The basic property public:

// mc as MovieClip with multiple frames
var dm:DataMix = new DataMix(mc);
    dm.width; // as Number
    dm.hight; // as Number
    dm.data;  // as Array [BitmapData,BitmapData,BitmapData,...]

The basic methods private:

//[1] function support
function movePosition(a:Number, b:Number):Number;
function dePercent(p:Number, s:Number = 0, e:Number = 100):Number;
//[2]
function getRecBase(mc:MovieClip):Rectangle;
function getListBase(mc:MovieClip, rec:Rectangle):Array;
function getBaseBitmapData(mc:MovieClip, rec:Rectangle, smoothing:Boolean ): BitmapData;
//[3]
function getRecActual(list:Array,rec:Rectangle):Rectangle;
function getViboty(mc:BitmapData,rec:Rectangle): Rectangle
function getListActual(list:Array, newrec:Rectangle):Array;
function getActutalBitmapData(bitmapdata:BitmapData, rec:Rectangle): BitmapData;

Version 1.0.0.2
In this version, DataMix only get true size of the MovieClip, it's not store the BitmapData
Changes in the Constructor

/**
* In special cases, we only get the size, no need to get data
* @param mc as MovieClip
* @param isdata if true get all including data else false only get size
*/
public function DataMix(mc:MovieClip,isdata:Boolean=true)

For example:

// mc as MovieClip with multiple frames
var dm:DataMix = new DataMix(mc);
    dm.width; // 100
    dm.hight; // 100
    dm.data;  // null

Version 1.0.0.3

Completely remove the excess in list BitmapData, you can see the difference in version 1 2 and 3

/**
   * @param mc Make sure you seted the movie correctly!
   */
  private function setup(mc:MovieClip,isdata:Boolean):void {
   var recBase:Rectangle   = getRecBase(mc);
   var listBase:Array      = getListBase(mc, recBase);
   var recActual:Rectangle = getRecActual(listBase, recBase);
   
   var listFace:Array  = getListActual(listBase, recActual);
   var recTrim:Rectangle = getTrimBitmapData(listFace);
   
   w = recTrim.width;
   h = recTrim.height;
   
   if (isdata) {
    clearListBase(listBase); // necessary!
    d = getListActual(listFace, recTrim);
   }else {
    clearListBase(listBase); // necessary!
    clearListBase(listFace); // necessary!
    d = null;
   }
  }
  /**
   * The function trim a bit transparent in the Bitmapdata
   * @param a list BitmapData actual, but non-trim
   * @return rectangle 
   */
  private function getTrimBitmapData(a:Array):Rectangle {
   var maxx:Number = NaN;
   var maxy:Number = NaN;
   var minx:Number = NaN;
   var miny:Number = NaN;
   var maxw:Number = NaN;
   var maxh:Number = NaN;
   var temp:Number = NaN;
   for (var i:int = 0 ; i < a.length; i++){
    var b:Rectangle = a[i].getColorBoundsRect(0xFFFFFFFF, 0x000000, false);

    minx = ((temp = b.x) < minx)?temp:(isNaN(minx))?temp:minx;
    miny = ((temp = b.y) < miny)?temp:(isNaN(miny))?temp:miny;
    maxw = ((temp = b.width) > maxw)?temp:(isNaN(maxw))?temp:maxw;
    maxh = ((temp = b.height) > maxh)?temp:(isNaN(maxh))?temp:maxh;
    
    maxx = ((temp = b.x + b.width) > maxx)?temp:(isNaN(maxx))?temp:maxx;
    maxy = ((temp = b.y + b.height) > maxy)?temp:(isNaN(maxy))?temp:maxy;
    
   }
   var maxwi:Number = maxx - minx;
   var maxhi:Number = maxy - miny;   
   return new Rectangle(minx, miny, maxwi, maxhi);
  }

Version 1.0.0.4

Creating source BitmapData that is used for a large image with contains render multiple images children.

// mc as MovieClip with multiple frames
var dm:DataMix = new DataMix(mc);
    //Return value bitmapData that is parse from data.
    dm.bitmap;  // as big BitmapData;

For example:

var dx:DataMix = new DataMix(mc); // mc as MovieClip with multiple frames
var bitmap:Bitmap = new Bitmap(dx.bitmap);
 addChild(bitmap);

Bitmap is taken from DataMix
