Thanks for the insight. I did something very similar, although I'm
using HBox/VBox components to layout my app so I had to put a VBox
wrapper around the image like this:
<mx:VBox id="image_01_wrapper" width="100"
height="100%" verticalAlign="middle" horizontalAlign="center">
<mx:Image id="image_01"
source="{'http://media.basspro.com/'+current_product.image_url_01}"
complete="{image_resize(image_01,100,75)}" alpha="0"/>
</mx:VBox>
Then my image_resize() function takes an Image object and desired
width/height as parameters:
private function image_resize
(img:Image,w:int,h:int):void {
var img_width:int =
img.content.loaderInfo.width;
var img_height:int =
img.content.loaderInfo.height;
if (img_width/img_height >= w/h) {
//image is wider than box
proportions - resize based on width
img.width = w;
img.height = w/img_width*img_height;
} else {
//image is taller than box
proportions - resize based on height
img.height = h;
img.width = h/img_height*img_width;
}
//Alert.show(img.width.toString() + "x" +
img.height.toString());
var fade_in:Fade = new Fade();
fade_in.target = img;
fade_in.alphaFrom = 0;
fade_in.alphaTo = 1;
fade_in.play();
}
I also added the fade in tween so that the images gradually fade in
when they have been resized. Anyway, your code below got me going.
Thanks!
