<p>A few minutes on the <a href="http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/display/BitmapData.html" rel="nofollow noreferrer">BitmapData LiveDoc Page</a> will take you where you need to go. Once you have your image loaded into a Bitmap variable, you can access its BitmapData property. Add a <a href="http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/events/MouseEvent.html#CLICK" rel="nofollow noreferrer">Mouse Click Event</a> Listener to the image and then use <a href="http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/display/BitmapData.html" rel="nofollow noreferrer">BitmapData::getPixel</a>. The example for getPixel shows how to convert the uint response to an rgb hex code.</p> <p>Here's a modification of the Example given on the BitmapData page that worked for me (using mxmlc - YMMV):</p> <pre><code>package { import flash.display.Bitmap; import flash.display.BitmapData; import flash.display.Loader; import flash.display.Sprite; import flash.events.Event; import flash.events.MouseEvent; import flash.net.URLRequest; public class BitmapDataExample extends Sprite { private var url:String = "santa-drunk1.jpg"; private var size:uint = 200; private var image:Bitmap; public function BitmapDataExample() { configureAssets(); } private function configureAssets():void { var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler); var request:URLRequest = new URLRequest(url); loader.load(request); addChild(loader); } private function completeHandler(event:Event):void { var loader:Loader = Loader(event.target.loader); this.image = Bitmap(loader.content); this.addEventListener(MouseEvent.CLICK, this.clickListener); } private function clickListener(event:MouseEvent):void { var pixelValue:uint = this.image.bitmapData.getPixel(event.localX, event.localY) trace(pixelValue.toString(16)); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
