I'm not sure how much you know about Flex or Actionscript, so i
decided to just give some example code:
<!--THIS IS THE IMAGE PORTION-->
<mx:Image id="myImage" source="pic.jpg"/>
<!--AND THIS IS THE ACTIONSCRIPT EMBEDED IN THE MXML-->
<mx:Script>
<![CDATA[
private var desiredWidth:int = 300
private function changeWidth():void
{
myImage.width = desiredWidth
}
]]>
</mx:Script>
In the first portion the image is defined in the mxml, note I defined
and id property as well as source. I then use the id again in the
actionscript. I used it in a function so a button could trigger that
function and change the width of the image to 'desiredWidth' variable
at runtime.
I hope this helps

Subject: [flexcoders] How to load an image using mx:Loader
Hello folks,
I'm a newbie in flex-world!
I need to load a Bitmap (.jpg) file using Flex3.
Now I've read a bunch of code that describes how to do this using
ActionScript 3. But I'm not very sure how Flex 3 and AS3 interact.
I've got the Flex 3 Builder Eclipse Plugin and I was hoping I could
find an example of loading an image using the <mx:Loader> tag. But
strangely I do not see many posts on this forum for this. Could it be
that this is the "wrong" way to load an image using Flex?
So, specifically, can someone:
1. Provide me with an example of using <mx:Loader> to load a .jpg
file.
2. Show me a simple example of how Flex3 tags and AS3 interact. For
example, if I wanted to build all UI components using Flex, but do all
Image manipulation using AS3.
Thanks in advance!
Pankaj
