Re: [Flashcoders] proportional image/clip scaling
Here are two functions I just copied from a class of mine:
_nScale is the scale it will be, assuming that a perfect fit to the
container box is 100%.
nLPW - is the width of the container box
nLPH - is the height of the container box
the code also centers the mc to the box.
private function resize(mc:MovieClip):Void
{
mc._xscale = mc._yscale = 100;
var nRatio:Number = 0;
if (isWider(mc))
{
nRatio = _nLPW / mc._width;
}
else
{
nRatio = _nLPH / mc._height;
}
mc._xscale = mc._yscale = nRatio * _nScale;
mc._x = _nLPW / 2 - mc._width / 2;
mc._y = _nLPH / 2 - mc._height / 2;
}
private function isWider(mc:MovieClip):Boolean
{
var nProportionPhoto:Number = mc._width / mc._height;
var nProportionBox:Number = _nLPW / _nLPH;
return nProportionPhoto > nProportionBox;
}

RE: [Flashcoders] proportional image/clip scaling
This is a very old function and needs tidying up but I tink it should
help
public function
getScaleToFit(mcChild:MovieClip,intHeight:Number,intWidth:Number,
blnOver100:Boolean):Number{
var intScale:Number = 100;
if(intHeight == undefined){intHeight = _root._height;}
if(intWidth == undefined){intWidth = _root._width;}
if(blnOver100 == undefined){blnOver100 = false;}
while((mcChild._height/100)*intScale > (intHeight)){
intScale--;
}
while((mcChild._width/100)*intScale > (intWidth)){
intScale--;
}
if((intScale == 100) && blnOver100){
while((mcChild._height/100)*intScale <
(intHeight)){
intScale++;
}
while((mcChild._width/100)*intScale <
(intWidth)){
intScale++;
}
intScale--;
}
return intScale;
}

Subject: [Flashcoders] proportional image/clip scaling
anybody have the math handy to proportionally scale one clip to another?
Meaning, let's say I load in an image that is 100w - 300h.
and I want to display it in an area that is 320w - 240h.
So I want to scale the original image clip to fit within the display
area, but show the entire image.
