Digital Picture Auto Correction in PHP?

Hi All,

Is there any script or dll that allows me to do
auto correction to digital pictures from PHP?

Thanks in advance,
Ehud

Well, I have no clue what 'auto correcting' is in your book.
But if you need imagemanipulation functions, go check the GD lib.
It is available on *nix and W$.

Just go to www.php.net for details:
http://nl3.php.net/manual/en/ref.image.php

To check if you already have the GD libs compiled in/linked just ask
phpinfo() and look for GD.
Note: Beware of the version of GD: Older GD libs (<2) cannot do what the
modern ones can (like truecolor, alphachannels, etc).
If you have a version >2, you are fine.

Thanks...

I ment auto level and auto white balance by 'auto correction'...

I will check this library, look very promising!
