No one has an idea? -.-
You're covering a lot of ground here with very little information regarding your design requirements...
Let's break this down:
Moving things around on the stage: search the help docs for "drag and drop". Fairly simple to accomplish.
'set your text': Not sure what this means. Allow user to type text into an editable TextArea, perhaps?
Uploading pictures: This depends on your back-end technology-- PHP? .NET? or ??? Use Google to search for "Flex file upload using PHP" or whatever you are using.
"Alive PDF-Output on server": Not sure what this means. I use Alive PDF in Flex, and it allows saving the PDF to user's HDD using a FileReference class, OR, opening the created PDF in a browser. I don't think you can save it to your server, unless you again resort to a file upload after saving it to the user's HDD, or perhaps sending it as a byte array w/o saving it locally. Search for this topic at AlivePDF site?
Sending PDF via email: Never tried this, sorry can't help you there. If you can somehow get the file uploaded to your server, you will need a back-end solution to then retrieve it and email it to yourself.
Like rtalton said , you are covering a lot of ground. I have used alive pdf, and it is possible to save the pdf to the backend. You have to create the pdf on the client , convert it to Base64 and send to your backend.
Thank you both for your answer. I'll try to explain it more:
For the 'drag and drop' with editable Text I found a solution, that seems to work fine for me.
Pictures > I'm on PHP and sure I'll try Google
(may the most important) convert it to an PDF: What I need is a solution like AlivePDF (or itself) which allows me to create a PDF like I want in and send it via Email from the backend to a special email-address. So as I can see AlivePDF doesn't support this directly and Flex itself also doesn't (which is unbelievable, because it is both from Adobe now!).
Maybe there is a backend like AlivePDF in PHP or something like this, which I can use or maybe you can explain me a bit more about this BASE64 way, because I've never done something like this before.
Or maybe - if this would be much easier - it would also help to create TIFF or high resolution JPEG instead PDF.
