    <p>Im loading images into Flash and using JPGEncoder to encode the image to a ByteArray and send this to AMF PHP which writes out the bytearray to a file. This all appears to work correctly and I can download the resulting file in Photoshop CS4 absolutely fine. When i try to open it from the desktop or open it back in Flash it doesnt work... Picasa my default image browser says "Invalid"</p> <p>Here is the code i use to write the bytearray to a file -</p> <p>$jpg = $GLOBALS["HTTP_RAW_POST_DATA"]; file_put_contents($filename, $jpg);</p> <p>That's it ... I use the NetConnection class to connect and call the service, do I need to say Im sending jpg data? I assumed that JPGEncoder took care of that. How can I validate the bytearray before writing the file? Do I need to set MIME type or something? </p> <p>Thanks - here is some code:</p> <pre><code>item.load(); function _onImageDataLoaded(evt:Event):void { var tmpFileRef:FileReference=FileReference(evt.target); image_loader=new Loader ; image_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, _onImageLoaded); image_loader.loadBytes(tmpFileRef.data); } function _onImageLoaded(evt:Event):void { bitmap=Bitmap(evt.target.content); bitmap.smoothing=true; if (bitmap.width&gt;MAX_WIDTH||bitmap.height&gt;MAX_HEIGHT) { resizeBitmap(bitmap); } uploadResizedImage(bitmap); } function resizeBitmap(target:Bitmap):void { if (target.height&gt;target.width) { target.width=MAX_WIDTH; target.scaleY=target.scaleX; } else if (target.width &gt;= target.height) { target.height=MAX_HEIGHT; target.scaleX=target.scaleY; } } function uploadResizedImage(target:Bitmap):void { var _bmd:BitmapData=new BitmapData(target.width,target.height); _bmd.draw(target, new Matrix(target.scaleX, 0, 0, target.scaleY)); var encoded_jpg:JPGEncoder=new JPGEncoder(90); var jpg_binary:ByteArray=encoded_jpg.encode(_bmd); _uploadService=new NetConnection(); _uploadService.objectEncoding=ObjectEncoding.AMF3 _uploadService.connect("http://.../amfphp/gateway.php"); _uploadService.call("UploadService.receiveByteArray",new Responder(success, error), jpg_binary, currentImageFilename); } </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.
