When you change the _width and _height properties, Flash automatically adjust the _xscale and _yscale properties to the correct values. Those values are being inherited by the next clip that is being loaded.

So the easiest way I've found is to set myClip._xscale=myClip._yscale=100 just after the clip loads. Then you can be sure that the size you are reading is the real size.

That is correct !
Adding this made it work as it should ... THX a lot !

myMCL.onLoadComplete = function (targetMC)
{
targetMC._xscale = 100;
targetMC._yscale = 100;

}

Like Jensen said; hide the content from the viewer until it's fully loaded, perhaps adding a preloader to each of ur files. If ur not allready familiar with the MovieClipLoader u should try lookíng at it. It gives u full control over the different stages of the loading process. the start, the progress, when its fully loaded and if u load SWFs when the actions in frame one is executet...

Hello, ive been trying with the mcloader,
and it all went fine, but now ive got a problem, I made a piece of code wich takes targetMc width and height, and based on that to set x an y for the targetMC. If targetMC (the picture) is bigger than Stage i rescale it wich goes fine as well, but when ive done a rescale of targetMc the next picture goes wrong, ill explain with code
So i do this
myMCL.loadClip(pathToPics+arrFilename[teller], "_level0.myMC1");
This gets called by a timer depending on an xmlfile ...
arrFilename contains pic1.jpg, pic2.jpg , pic1.jpg
it is processed by this code

myMCL.onLoadInit = function (targetMC)
{
trace ("Current targetMC dimensions");
trace ("Target Width = "+ targetMC._width);
trace ("Target Height = "+ targetMC._height);
var scaleratio;
if (targetMC._width > Stage.width){
trace("resize width");
scaleratio = targetMC._width / Stage.width;
trace("scaleratio= "+ scaleratio);
targetMC._width = Stage.width;
targetMC._height = targetMC._height/scaleratio;
}
trace("tussenin");
trace ("Target Width = "+ targetMC._width);
trace ("Target Height = "+ targetMC._height);
if (targetMC._height > Stage.height){
trace("resize height");
trace ("Target Height = "+ targetMC._height +"/ stageheight " + Stage.height );
scaleratio = targetMC._height/ Stage.height;
trace("scaleratio= "+ scaleratio);
targetMC._height = Stage.height;
targetMC._width = targetMC._width/scaleratio;
}
targetMC._x = (Stage.width-targetMC._width)/2;
targetMC._y = (Stage.height-targetMC._height)/2;
trace ("Rescaled targetMC dimensions");
trace ("Target Width = "+ targetMC._width);
trace ("Target Height = "+ targetMC._height);
}

the trace result :

Current targetMC dimensions
Target Width = 1023
Target Height = 682
tussenin
Target Width = 1023
Target Height = 682
Rescaled targetMC dimensions
Target Width = 1023
Target Height = 682

Current targetMC dimensions
Target Width = 2832
Target Height = 2128
resize width
scaleratio= 2.765625
tussenin
Target Width = 1023.95
Target Height = 769.45
resize height
Target Height = 769.45/ stageheight 768
scaleratio= 1.00188802083333
Rescaled targetMC dimensions
Target Width = 1022
Target Height = 768

10
Current targetMC dimensions
Target Width = 369.15
Target Height = 246.15
tussenin
Target Width = 369.15
Target Height = 246.15
Rescaled targetMC dimensions
Target Width = 369.15
Target Height = 246.15


So problem is : when loading pic1.jpg the first times it gets it dimensions right : 1023 * 682 : ok
when loading pic2 which is to big it gets scaled wich goes fine : ok
when loading pic1 for second time things go wrong cause it has dimensions
369.15* 246.15
It has something to do with changing the targetMC properties, i might need to reset them after each pic or something
Any ideas, thanks for helping

Hi!

You get it after it is fully loaded. So what you would normally do is hide
the MC you are loading into (for example setting _alpha to 0) and then after
it is fully loaded, you get the _width and _height from that MC. Then resize
and position it before making it visible (for example with _alpha = 100).
