Saving Images
Jan 2nd, 2010, 1:29pm  
How would I go about saving the output from a processing app onto my server?

Say for instance some one uses a processing app, that I am hosting, to draw a picture. How could I save that picture to my server?

Or just look for the library postToWeb, based on my work on the second given link (IIRC), it should be a good start.

PhiLo, that would definetly be what I am looking for thank you.

Do you know how this library works? I am interested in understanding it as well as using it.

Whats the basic operations of it?

When I save a file in an applet this turns that image into an array containing the information for each pixel? Then passes that array in the header of the URL to a PHP file that makes it into an Image saved to the server?

Basically, yes, except that array is passed in a POST (Mime) request, not in the URL (would be a bit long...). And the array of pixels is transformed to a full image file content (PNG, Jpeg, etc.) by Java before sending, so that the PHP side receives actually a file upload request, which it processes as such with some caution (to avoid hacking).
