RE: [flexcoders] Re: Transfer Images with FDS

[Jeff Vroom]

Just to give you a little more complete answer to this.  If you look at the flash.display.BitmapData class, it has the ability to populate a Bitmap from a byte array of pixel data, so you could transfer the bytes to the client and display them there.  Unfortunately the graphics data is not going to be compressed directly but we do have gzip compression support in the player as part of the flash.utils.ByteArray class.   In the Java side you’d compress the data using a gzip library and in the flash side you’d uncompress it.  I’m not an expert on the graphics support in flash so someone please correct me if this is not the best approach.   I think alternatively you could request the image via a URL in the flash player (via the Loader class) but just generate it in memory and write the response data directly into the socket.  That would potentially be more efficient on the client side since the native code would be processing the image data, though if you go the byte array route, most of the operations are happening in native code anyway.  Also your original data might be in jpeg format not just a pure 2D array of pixel data so that might be more convenient.     Jeff   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Matt Chotin Sent: Monday, October 09, 2006 4:08 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Re: Transfer Images with FDS   I guess you could probably send it as a binary array and then convert it on the client-side?   From: [EMAIL PROTECTED]ups.com [mailto:[EMAIL PROTECTED]ups.com] On Behalf Of cheftimbob Sent: Monday, October 09, 2006 5:05 AM To: [EMAIL PROTECTED]ups.com Subject: [flexcoders] Re: Transfer Images with FDS   bump --- In [EMAIL PROTECTED]ups.com, "cheftimbob" <[EMAIL PROTECTED]..> wrote: > > We have a middle layer that is responsible for storing files in a > repository.
