How to save an image-file on server through Java a

问题:

I have a paint application that runs as a Java applet. I need to save the contents of the canvas on server machine in any image-format typically PNG. Please help!

回答1:

You might be interested by the code I wrote for Processing, which is basically Java code. Re: save to web --- image export. Earlier in the thread I explain some precautions to be taken with such application (to avoid flooding a server from a malicious user) and I give the corresponding PHP code.

You need to do two things:

1. Generate an PNG image file in your applet - Writing/Saving an Image
2. Post the image file to some server-side CGI/servlet which will store the image - How do I upload a file to my servlet or JSP?

What are you running on the server? PHP? Rails? JSP? .NET?
