This function is what I am looking for in one of my Flex projects, but as a newby the code snippets are not wholly coherent to me.

Can you PLEASE :) make the project available as a zip? I was considering Sothink sqf to flex but would love it if you could share this in entirety.

pretty please??

I have one question:
Do you know if this cfc working with coldfusion 8? I have tried and I got one error!
In coldfusion 7 working fine!

Ah, yes ColdFusion needs to be updated to version 7.0.2 to use AMF3 which is needed to send a ByteArray. So without these capabilities the simplicity is lost some what. Sorry for not pointing out those requirements.

Hey Mike,

The project is an AS3 only project, no mxml involved, only AS3 in Flex Builder.
My guess is that it’s an AMF0 – AMF3 problem or it could be a coldfusion
version issue.

Coldfusion would not accept my img data as a binary.

I fixed the problem by encoding the jpgencoded bytearray into a base64 string.
That base64 string is send to my cfc method, which decodes it into a binary
using toBinary( myBase64EncodedString ).

This binary is written with the cffile tag.

Quite a bug hunt, but it was worth it! The base64 encoder is not an Adobe class;
as it is not a part of the AS3 packages, but it’s available in the Flex packages.
I downloaded a class I found on the net.

When you say no Flex involved do you mean you are using the flash 9/CS3 beta or did you mean no MXML involved.

How did you set up the remoting object – remoteCon??

I see you have renamed the ColdFusion function did you change anything else??

If you send me a more complete code example I can take a look for you.

Mike.

Thanks for this great example.
However, I ran into a problem in a AS3 only project, no Flex involved.
Do you have an idea what is happening here ?

This code always throws an error: The argument IMG passed to function saveToDisk() is not of type binary.

Actionscript:
=========
var picture:Picture = Slideshow.getInstance().getPicture();
var bmp:BitmapData = new BitmapData(picture.width,picture.height,false);
bmp.draw(picture);
var myPNG:ByteArray = PNGEncoder.encode(bmp);
remoteCon.saveToDisk(“png”,myPNG);

Coldfusion:
========

….

Btw: these classes are now an integral part of the open source Adobe AS3 corelib:

Stunningly simple indeed … should be a snap to add a browse capability for images in case the user doesn’t have a webcam :) Impressive!
