[thelist] Flash: Scaling a loaded image to Xpx and Ypx?

[Benjer]

This probably looks a bit daunting if you've never used enterFrames...

function displayImg(img, imgMC, imgHeight, imgWidth) {
    imgMC.loadMovie(img);
    //check the download status of the external
    //movie once every frame
    this.onEnterFrame = function() {
        //trace the percentage of the movie that has loaded
        percent =
(this.holder.getBytesLoaded()/this.holder.getBytesTotal())*100;
        if (!isNan(percent)) {
            trace(percent+"% loaded");
        } else {
            trace("0% loaded");
        }
        //once fully loaded we can re-size the image
        if (percent == 100) {
            img._width = imgWidth;
            img._height = imgHeight;
            delete this.onEnterFrame;
        }
    }
}
displayImg("http://localhost/Test/249-2.jpg", "myImage", 125, 200);
