Setting width before or after rotation doesn't give same result

[Pioo]

Hi,

I got a blue square clip (50x50), I wanna transform it to be 100x50 and 45° rotated.
When I set the width before the rotation no problem, but when I set the rotation first my clip is shorter than 100px...
Why is that?

var clip:Sprite=new Sprite();
var clip2:Sprite=new Sprite();
var shape=new Shape();
shape.graphics.beginFill(0x0000FF);
shape.graphics.drawRect(0, 0, 50,50);
shape.graphics.endFill();
var shape2=new Shape();
shape2.graphics.beginFill(0x0000FF);
shape2.graphics.drawRect(0, 0, 50,50);
shape2.graphics.endFill();
clip.addChild(shape);
clip2.addChild(shape2);
this.addChild(clip);
this.addChild(clip2);
clip.y=clip2.y=400;
clip.x=250;
clip2.x=400;
clip.rotation=45;            
clip.width=100;
clip2.width=100;            
clip2.rotation=45;
trace(clip.width);
trace(clip2.width);

Not an expert, but found a discussion that could probably provide you with insights actionscript 3 - Setting movieClip width and height fails - Stack Overflow

Try setting the x scale instead of the width.

Actually I found out this behaviour explanation..

When a clip is rotated its dimension change, and when you set the width or height it just set the scale accordingly to its current dimension.
In my case :

this.addChild(clip);     //Width :50
clip.rotation=45;        //Width : 70.7
clip.width=100;          // -> clip.scaleX = 1.4 (100/70.7)
                         //Width : 85.35 (not 100)
