image width and height

[jjyang]

Hi there,

i have already imported the images externally. but i would like to put them in the BitmapData which needs to specify the width and height. i dont want to hard code it, i want to get the width and height of the image itself and then assign to the width and the height of the Bitmapdata.

i can't seem to find any way to do that. pls help.

thank you!

load them in with movieclip loader.. then onLoadInit() method you can get the width and height.

onLoadInit is for AS2, does anyone have a solution for AS3?

[Mazoonist]

var loader:Loader = new Loader();

var bmd:BitmapData;
var bitmap:Bitmap;

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
loader.load(new URLRequest("yourfile.jpg"));

function imageLoaded(event:Event):void {
    //event.target is loader.contentLoaderInfo, and already
    //has the information as to the width and height of
    //the loaded image: 
    
    bmd = new BitmapData(event.target.width, event.target.height);
    bmd.draw(loader);
    bitmap = new Bitmap(bmd);
    addChild(bitmap);

    //alternatively, since event.target.content is a bitmap object,
    //try uncommenting this code and commenting the previous block:
    
    /*bitmap = event.target.content;
    addChild(bitmap);*/
}

width and height parameters are ignored with imported bitmaps.
ie: you can specify 0,0 with imported bitmaps.
