    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 imagemanipulati on functions, go check the GD lib.
    It is available on *nix and W$.

    Just go to www.php.net for details:


    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!

      Have a look at phpthumb
      phpThumb() is the PHP thumbnail generator. Many image processing options (blur, sharpen, colorize, saturation, gamma, etc) and support for many input image formats across all versions of GD, including JPEG, PNG, GIF and BMP (even without ImageMagick).
