Ok imagine there is movieclip named my\_clip inserted on stage, library movie clip instance with ‘subclip’ linkage and BitmapData “my\_bitmap\_data”

my\_clip.attachMovie(‘subclip’,‘subclip’,1)  
my\_clip.subclip.\_x-=my\_clip.subclip.\_width/2  
my\_clip.subclip.\_y-=my\_clip.subclip.\_height/2

my\_rect = new Rectangle(my\_clip.subclip.\_x,my\_clip.subclip.\_y, my\_clip.subclip.\_width, my\_clip.subclip.\_height)

my\_bitmap\_data.draw(my\_clip,new Matrix(),new ColorTransform(),‘normal’,my\_rect);

As you can see I wanna take pixel informations from my\_clip (containing subclip which is centered and its pivot point is in the middle) but when I try to insert bitmap data into another clip via attachBitmap it gives only one quarter of the subclip (down-right) which means draw method ignored all graphic under 0 coordinate value. How is this possible?
