I am building an avatar-generator for a PHP/MySQL site I am working on. It uses CSS to layer multiple .png files to create the background, body, facial expressions, etc. for a user's avatar. This I have covered.
I want to add a feature to my site that will allow the user to download their layered avatar "image" as one .jpg file. Is this even possible? I think I have seen this functionality before but can't recall the site where I saw this now.
Of course, I could come up with a series of pre-generated files that would cover all of the computations possible with my images, but with somewhere around 200 objects to choose from and a maximum of 10 layers of choices, the number of permutations possible is somewhere around 8.14702044e+22! Obviously, this is possible for me to do but I would be old and gray before completing the task!
Poking around the Internet has led me to believe there might be some way to "screen cap" - with what software and if it can capture a small section of the screen I don't know. Besides, would this bog down my site (which is currently running at top speed)?
I've searched through Stack Overflow for similar questions but didn't find anything that addresses my problem specifically. That said, I am not certain what to even search for (the precise terminology) as this concept of layering and saving as one image is foreign to me.
