Subject: [Flashcoders] tracing height
I have:
_root.imageMovie.loadMovie(stepImageArray[0]);
sizeImage();
function sizeImage () {
trace(_root.imageMovie._height);
}
But I keep getting 0 I am guessing because the trace is fired before
the
image is loaded... how can I make sure this function does not fire
until
the image is loaded. I tried:
_root.imageMovie.onLoad = function() {
}
But that does not seem to fire at all....
My ultimate goal is to control the size of the image that is being
loaded to make sure it is not too big....
Thanks!
Hi Theodore,
There might be better ways than what I am using, but this works. For
each image I create a new movieclip which onEnterFrame resizes the
target loadMovie image to a set size, and then removes itself so it
doesn't keep working needlessly.
This is cut and pasted from a project where images are sourced from XML,
so it might have some extraneous ...
mrand=Math.round(Math.random()*3000);
tname='img'+mrand;
_root.createEmptyMovieClip(tname, imagedepth); imagedepth++;
_root['img'+mrand].createEmptyMovieClip('md', imagedepth);
_root['img'+mrand].md.loadMovie(images.childNodes[i].attributes['imgloc']);
_root['img'+mrand]._x=images.childNodes[i].attributes['x'];
_root['img'+mrand]._y=images.childNodes[i].attributes['y'];
trace(images.childNodes[i].attributes['imgloc']);
// image sizer
mrand=Math.round(Math.random()*3000);
sizer=tname+'sizer'+mrand; imagedepth++;
_root.createEmptyMovieClip(sizer, imagedepth); imagedepth++;
_root[sizer].pushw=images.childNodes[i].attributes['w'];
_root[sizer].pushh=images.childNodes[i].attributes['h'];
_root[sizer].clipname=tname;
//trace(images.childNodes[i].attributes['w']);
_root[sizer].onEnterFrame=function(){
trace(this.clipname + ' ' + this.pushw + ' ' + this.pushh);
_root[this.clipname]._width=this.pushw;
_root[this.clipname]._height=this.pushh;
//trace(this.clipname); // img0sizer
if(!init){ init=1; }
if((this.pushw)&&(this.pushh)&&(init>30)){
// counts to 30 frames and quits, should be enough
this.removeMovieClip();
}
init++;
}
