savetoweb

This hack is for saving files to a webserver through an applet.

I've used it to save postscript, jpg, and text-files.

the saveToWeb_ functions are all examples of how to save different files, the one just called saveFile is the most dynamic of them all, and handles byte-arrays.

Syntax:

postToWeb ( String Title, String File-Extension, String SaveFolder, byte[] Data, boolean Open file when done);

And remember, when you select a folder to write to, it has to be writable.

There are tons of ways to set rights, so however you do it, change the rights to the folder you are going to save to to 777 (chmod 777)

// i.e. \\

url = "http://processing.org/"; // the saveFile.php has to be here \\



// then i want to save all jpgs to a folder called savedJPG \\

saveToWeb_saveJPG("mytitle","savedJPG",get(0,0,width,height));

P.S.

For saving a jpg, you have to use this code.
