RE: [flexcoders] Posting PNG to server
If you are using AMF3 (RemoteObject), you can serialize binary data
without any conversion. If you are trying a standard HTTP post, I would
use a HTTPService with the method= POST. Then you have to Base64
encode the binary data and attach it to the parameters of the http
service. On the server side, you will need to decode the base64 encoded
data back into binary.
Example:
mx:HTTPService
id=httpService
showBusyCursor=true
useProxy=false
method=POST
resultFormat=text
url=/BinaryData/cf/HTTPImageSave.cfm
result=onResult('Data Saved via mx:HTTPService')
fault=onFault(event) /
private function base64Encode( data : ByteArray ) : String
{
var encoder : Base64Encoder = new Base64Encoder();
encoder.encodeBytes( data );
return encoder.flush();
}
private function sendData() : void
{
var data : ByteArray = encoder.encode( myPngByteArray );
var params : Object = { data : base64Encode( data ) };
httpService.send( params );
}
In ColdFusion, you can decode the base64 data simply by using the
toBinary function. Other languages have similar functions as well.
Just a FYI... using the JPG instead of PNG requires significantly less
bandwidth time to post the data to the server. Base64 encoding the
data also increases the size of the data being transferred across the
wire. It is much more efficient to use a remoteObject method with
JPG-compressed data.

I have done this with ColdFusion using the RemoteObject tag. Can you
use one of the remote object php tools to pass the binary data?

Re: [flexcoders] Posting PNG to server
Franto, I posted a reply on your question today in the other thread ; )
Re: [flexcoders] Posting PNG to server
1 more thing can be sent in 1 URLRequest post data + PNG i think its not possible, but just asking because for png i need to set request.contentType = multipart/form-data; but it removes ll POST vars (text) is it possible to merge these 2 kinds of data?
