RE: [Flashcoders] Image resizer that maintains ratio
Would that optimize it? I could be wrong but I thing both these version's
would compile to the same byte code.

You could probably optimize a little bit by removing the Math
function...
mc._width = maxW;
mc._height = maxH;
if ( mc._xscale mc._yscale ) {
mc._xscale = mc._yscale;
}
else {
mc._yscale = mc._xscale;
}
I don't think I can be done more effiently than that. Anyone?

The _scale property is a percentage value if you have a 800x600
image and set _xscale=50 and _yscale=50, you get a 400x300 image

RE: [Flashcoders] Image resizer that maintains ratio
Yup, sorry for being vague. It's the maintaining of the ratio while the user resizes that I'm after. A user uploads an image, I load this image into a container and force it to fit into a maximum and minimum width and height. Within this container the user can resize the image without expanding out of the container and all the time maintaining the original ratio. The resizing will be done by dragging an anchor point like this: http://www.adrianlynch.co.uk/temp/resizer.gif I have it working but it allows the image to be resized anyway the user chooses. I also need to make the anchor stick to the bottom right hand corner of the image. I think I will work this out eventually but I wanted to see if there was anything out there already that I could glean some ideas from. Thanks.

This might be overkill, but feel free to use the TransformManager and/or TransformItem class(es) available at http://www.greensock.com/ActionScript/TransformManager.

My scaleToFit function. Probably not the most awesome thing, but it does
the job
private function
scaleToFit(target:Object,clipRect:Rectangle,maintainAspect:Boolean){
var w:Number = clipRect.width;

RE: [Flashcoders] Image resizer that maintains ratio
Ah nice one Jack. That's just what I was looking for. Will let you know how I get on.

Re: [Flashcoders] Image resizer that maintains ratio
The _scale property is a percentage value
if you have a 800x600 image and set _xscale=50 and _yscale=50, you get a
400x300 image

Hi,
that IS weird, because if your image is 800x600, you are saying:
target_mc._xscale = target_mc._yscale = 800;
which is probably not what you want^^

RE: [Flashcoders] Image resizer that maintains ratio
Here's how I do it:
function maintainAspect ( mc:MovieClip, maxW:Number, maxH:Number ) :Void
{
mc._width = maxW;
mc._height = maxH;
mc._xscale = mc._yscale = Math.min( mc._xscale, mc._yscale );
}
