unfortunately after giving this a solid newbie try, getting stumped
converting the binary data to an image. what i've tried in my item
renderer is:
// legends?
thisNode=XML(TreeListData(super.listData).item);
if (thisNode.legend.length()) {
var loader:Loader=new Loader();
var ba:ByteArray=new ByteArray();
ba.writeObject([EMAIL PROTECTED]);
loader.loadBytes(ba);
addChild(loader.content);
}
keeps throwing "Error #2124: Loaded file is an unknown type." at
runtime. any ideas?
thanks.

hi greetz,
i've given that method a solid newbie try but i can't get the data
loaded into a ByteArray from the xml. i've tried
// any legends in this?
thisLegend=XML(TreeListData(super.listData).item.legend);
if (thisLegend) {
var loader:Loader=new Loader();
var ba:ByteArray=new ByteArray();
ba.writeObject([EMAIL PROTECTED]);
loader.loadBytes(ba);
addChild(loader.content);
}
but flex keeps throwing runtme "Error #2124: Loaded file is an unknown
type." errors.
any ideas?
thanks.

Hi there! The best way I found to work with binarys/xml is Base64...

[flexcoders] Re: binary in xml
To anyone interested still:
AS3 function to convert a Base64 encoded Image and display it in
flex!
private function testIt():void
{
var b:Base64Decoder = new Base64Decoder();
b.decode('base64 encoded image string goes here');
var bA:ByteArray = b.flush();
var l:Loader = new Loader();
l.loadBytes(bA);
var img:Image = new Image();
img.addChild(l);
img.scaleContent = true;
img.scaleX = .5;
img.scaleY = .5;
t.addChild(img);
}
The "t" object is just a Canvas object in the application. It's
just a rough outline. You can load the string (which is easier and
more likely what you'll actually do) via HTTPService to use in the
decode function. That way, you'll be able to have \n characters and
there won't be any errors thrown.
Hope this helps someone out there! :D

Re: [flexcoders] Re: binary in xml
I think it has something to do with the way you write the information to the byte array. If you try to write it as an object, the information (a string in your case) will be translated to the AMF equivalant of the string, which is not the actual data you need. So somehow (and i dont have enough experience with this, nor the time to test it myself right now) you should convert the string of bytes to actual bytes. Check out the different write options on the byte array class, and maybe start another thread to get help converting a string of bytes to actual bytes. Hope you get there, and when you do, please post the solution :) Greetz Erik __._,_.___ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Software development tool Software development Software development services Home design software Software development company Your email settings: Individual Email|Traditional Change settings via the Web (Yahoo!

The flash player is capable of runtime loading of the PNG file format, so that should not pose a problem.

yeah i've tried that. but only seems to work for static data.
i've added nathan's method to the custom renderer's creationComplete &
it works fine when the data is static (see snippet below). but as soon
as i start pulling the xml from a java server via cf, i start getting
"TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at graphicRenderer/___HBox1_creationComplete()." errors. there's a
text widget in the same renderer that displays the text fine.
http://www.adobe.com/2006/mxml"; width="400"
height="40" creationComplete="convertToImage(data.swatchLegend);">
private function convertToImage(hex:String):void {
var b:Base64Decoder = new Base64Decoder( );
b.decode(hex);
var bA:ByteArray = b.flush();
var l:Loader = new Loader();
l.loadBytes( bA);
var img:Image = new Image();
img.addChild(l);
this.addChild(img);
}
