James,
Using RemoteObject I've uploaded bitmap snapshots without previously saving the
bytes to disk, using CF as a backend. Not exactly sure how you'd do this with
PHP, but I'm sure it's doable. You'd probably have to use some version of
AMFPHP.

Subject: [flexcoders] Re: Uploading An Image Without Browse
Cheers Jeff. I'm sure that'd work too. I've found a way around it and can now
allow users to upload without the browse. The problem is though I now want it
to upload the file without it having to save it on the user's machine first. At
the moment my code snapshots the html component, saves this as a bitmapdata,
resizes this bitmapdata, then a jpegencoder turns this bitmapdata into a jpg
file which is named after whatever the user has entered into a text input
component in my app. It then uploads this jpeg from the location it's saved to.
I'm wondering is there any way of me editing my code so it uploads the jpeg
straight away rather than storing it on the machine too? Here's my script code
containing the function which does all this:-
mx:Script
![CDATA[
import mx.graphics.codec.JPEGEncoder;
import mx.graphics.ImageSnapshot;
private var imageuploadurlRequest:URLRequest;
private var serverSideScript:String = *my upload php file goes
here*;
private function imageuploadinit():void {
imageuploadurlRequest = new
URLRequest(serverSideScript);
}
private function takeSnapshot(event:Event) :void{
var bigbmd:BitmapData =
ImageSnapshot.captureBitmapData(linkviewer) ;
var scale:Number = 0.50;
var matrix:Matrix = new Matrix();
matrix.scale(scale, scale);
var smallbmd:BitmapData = new BitmapData(bigbmd.width *
scale, bigbmd.height * scale, true, 0x00);
smallbmd.draw(bigbmd, matrix, null, null, null, true);
var jpgEncoder:JPEGEncoder = new JPEGEncoder( 100 );
var ba:ByteArray = jpgEncoder.encode(smallbmd);
var enteredimagename:String = titleentry.text;
var file:File =
File.applicationDirectory.resolvePath(('assets/createdimages/')+enteredimagename+('.jpg'));
var wr:File = new File(file.nativePath);
var stream:FileStream = new FileStream();
stream.open( wr, FileMode.WRITE);
stream.writeBytes ( ba, 0, ba.length );
stream.close();
imagesnapshotpreview.source=(('assets/createdimages/')+enteredimagename+('.jpg'));
file.upload(imageuploadurlRequest);
}
]]
/mx:Script

Using the FileSystem API and ByteArray you can save/read/upload images
automatically, using your middleware of choice without the user having to
browse and select the image.

My app has a html component which allows the user to enter a website into it.
When the website is fully loaded a snapshot is made of the html component and
then saved in the application directory automatically. I want this file to
then automatically upload to my server rather than just being saved on in the
app directory. I can easily do it using the browse method but can't figure
out how to get it to simply go straight to the server without the user having
to save it somewhere and then browse to upload it if that makes sense..

When you say take a snapshot, what do you mean?

Is there any way to do this and does anyone know of any similar examples?
All I can find is uploading via the browse function.
