Getting targetObject's scaled width and height [SOLVED]

Recommended Posts

Hello,

 

I am needing to read the width and height of a transformItem as if it were not rotated. The .width and .height property seem to take the rotation into account, meaning that I get the value that I need only when rotation == 0.

 

I figured I might be able to get this value from the bounds.width/height value, but I am trying to read the value when the transformItem is NOT selected, in which case "bounds" seems to be null. Is there an explicit value for this, or do I need to perform a calculation. If so, what is it?

I got a close value by taking the scaleX/scaleY value of the transformItem and multiplying it by my display object's original size. The calculation isn't perfect though. If my display object is 100x100, when I rotate it, it will become. 99.XXXXXXXXXX.

 

This is okay I think, unless you know a way to get a perfect reading. (by that, I mean that when I rotate it, the width and height STAY 100).

Nevermind, that didn't work either. The scaleX and scaleY must reset themselves after they are deselected. Any hints?

Use my MatrixTools class and try something like this:

 

function getUnrotatedWidth($mc:DisplayObject):Number {
   var bounds:Rectangle = $mc.getBounds($mc);
   return bounds.width * MatrixTools.getScaleX($mc.transform.matrix);
}

function getUnrotatedHeight($mc:DisplayObject):Number {
   var bounds:Rectangle = $mc.getBounds($mc);
   return bounds.height * MatrixTools.getScaleY($mc.transform.matrix);
}
