Can the data not be passed simply as a ByteArray instead of a base64 string? This is from the Adobe documentation for URLRequest:
--------------------- data property An object containing data to be transmitted with the URL request. This property is used with the method property. In Adobe AIR, data is sent when any HTTP method other than GET is used. In Flash Player, data is set when the POST HTTP method is used. The URLRequest API offers binary POST support and support for URL-encoded variables, as well as support for strings. The data object can be a ByteArray, URLVariables, or String object. The way in which the data is used depends on the type of object used: If the object is a ByteArray object, the binary data of the ByteArray object is used as POST data. For GET, data of ByteArray type is not supported. ----------- My problem is that I am also deficient in my experience with servlets and don't know how to decode a byte array there, but this is how I send the byte array var imageSnap:ImageSnapshot = ImageSnapshot.captureImage(component); var imageByteArray:ByteArray = imageSnap.data as ByteArray; var request:URLRequest = new URLRequest(imgServURL); request.data = imageByteArray; request.method = URLRequestMethod.POST; navigateToURL(request); --- In flexcoders@yahoogroups.com, leds usop <[EMAIL PROTECTED]> wrote: > > without remoting, and using string param only, encode the image as jpeg or > png (depending on your requirement) . then convert it to base64 string which you can pass to the serlvet via post (or get, whatever) . Then decode at the backend accordingly as a jpeg file or png file which is you can make available to the user. This is not the fastest solution performance-wise but it does get the job done expecially for snapshots. > > --- On Thu, 6/26/08, netdeep <[EMAIL PROTECTED]> wrote: > From: netdeep <[EMAIL PROTECTED]> > Subject: [flexcoders] image snapshot in flex > To: flexcoders@yahoogroups.com > Date: Thursday, June 26, 2008, 12:47 AM > > > > > > > > > > > > I'd like to add a button so the user can snapshot a graph in my > flex app. I can do this storing > > it on the server with Java, but I'd like for the user to have direct access > to it.
