note 48039 added to function.imagefilter

I was wondering if anyone knows how to lighten images using PHP4. I have this installed on my server and I am looking for a function that will allow me to brighten/darken images. I also have GD installed. ---- Manual Page -- http://www.php.net/manual/en/function.imagefilter.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48039 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48039&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48039&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48039&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48039&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48039&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48039&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48039&report=yes Search -- http://master.php.net/manage/user-notes.php
