The object view area is cut off if they come out properly reduced by dragging the window.
Obtain advice should be resolved in any way

You have to keep the aspect ratio to solve the problem.
Here is my resize function for example. You can change and use it for your needs.

private function SetSize(width:Number, height:Number, pos:Point, keepAspectRato:Boolean = true, fixedWidth:Number = 1280):void
{
 var aspectRatio:Number;     
 var starlingHeight:Number;
 var starlingWidth:Number;     
 var containerHeight:Number;
 var containerWidth:Number;
 var delta:Number;
 
 aspectRatio = 9.0/16.0;
 
 if (keepAspectRato)
 {
  starlingWidth = fixedWidth;
  starlingHeight = starlingWidth*aspectRatio;  
  containerWidth = width; 
  containerHeight = containerWidth*aspectRatio;
  
  if (containerHeight > height)
  {
   delta = height/containerHeight;
   starlingHeight *= delta;
   starlingWidth *= delta;
   containerHeight *= delta;
   containerWidth *= delta;
  }
  
  
  starlingHeight = Math.round(starlingHeight);
  starlingWidth = Math.round(starlingWidth);
  containerHeight = Math.round(containerHeight);
  containerWidth = Math.round(containerWidth);
 }
 else
 {
  starlingWidth = Math.round(fixedWidth);
  starlingHeight = Math.round(starlingWidth*aspectRatio);  
  containerWidth = Math.round(width); 
  containerHeight = Math.round(height);    
 }
 
 starlingBackLayers.Resize(starlingWidth, starlingHeight);
 starlingFrontLayers.Resize(starlingWidth, starlingHeight);
 view.x = Math.round((width-containerWidth)/2);
 view.y = Math.round((height-containerHeight)/2);
 view.height = containerHeight;
 view.width = containerWidth;     
 stage3DProxy.x = Math.round(pos.x+(width-containerWidth)/2);
 stage3DProxy.y = Math.round(pos.y+(height-containerHeight)/2);
 stage3DProxy.height = containerHeight;
 stage3DProxy.width = containerWidth;  
}

I have a simple resize function but this is quite nice and interesting to check out, thanks for sharing cyberix3d.

The idea behind this Resize function is to keep the aspect ratio while resizing your game.
If the window width is bigger than the window height you should see black strips on the left and right sides.
If the window height is bigger than the window width you should see black strips on the upper and lower sides.
That way your image won’t be cut.
See the attached pictures for better understanding what the Resize function should do.
If the function I gave you is not working, try to implement what I described.
