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 imagemanipulati on 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.

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

I will check this library, look very promising!
