scale to fit after rotation

[bhoffmann 0 Likes (Newbie)]

I am trying to round off rotations to the neatest 90 degrees and then scale the transform items to fit to the left or right side of the stage. I know how to round off the rotations, but I can't seem to get the positioning and the scaling right (because the x and y values change after the rotation).

 

Here is the code I am using:P

 

private function rotateAroundCenter (ob:*, angleDegrees:Number, ptRotationPoint:Point):void {
		var m:Matrix=ob.transform.matrix;
		m.tx -= ptRotationPoint.x;
		m.ty -= ptRotationPoint.y;
		m.rotate (angleDegrees*(Math.PI/180));
		m.tx += ptRotationPoint.x;
		m.ty += ptRotationPoint.y;
		ob.transform.matrix=m;


	}

private function scaleToFit($side)
{

		var itemAbsRotation:Number = Math.abs(tItem.targetObject.rotation);
		var rotateNum:Number = 0;
		var ptRotation:Point = new Point(_currRollOver.width/2, _currRollOver.height/2);

		if(itemAbsRotation > 0 && itemAbsRotation < 135)
		{
			rotateNum = roundToNearest(90, itemAbsRotation);


		}else if(itemAbsRotation > 134 && itemAbsRotation < 213)
		{

			rotateNum  = roundToNearest(180, itemAbsRotation);

		}else if(itemAbsRotation > 213 && itemAbsRotation < 45)
		{
			rotateNum  = 0;
		}

		rotateAroundCenter(_currRollOver.targetObject, rotateNum,ptRotation);


		if(imgInfo.type == "COLOR")
		{
			pX = _mainAppStage.x;
			pY = _mainAppStage.y;

			if($which == "left")
			{
				_currRollOver.width = _mainAppStage.width/2;
				_currRollOver.height = _mainAppStage.height;
				_currRollOver.x = pX;
				_currRollOver.y = pY;


			}else if($which == "right")
			{
				_currRollOver.width = _mainAppStage.width/2;
				_currRollOver.height = _mainAppStage.height;

				if(mirrorOffset == false)
				{
					_currRollOver.x = _mainAppStage.width/2 + _currRollOver.width/2 + 2;
					_currRollOver.y = _mainAppStage.y;
				}else 
				{
					_currRollOver.x = _mainAppStage.width + _currRollOver.width/2;
					_currRollOver.y = _mainAppStage.y;
				}
}
}
