The image sharpen function (by Alex R. Austin) provided below seems to be very resource hungry and I couldn't make it work on two different servers - trying to sharpen a 413 x 413 image I ended up with "Fatal error: Allowed memory size of 8388608 bytes exhausted" or "Internal Server Error" or the script terminated without notice. Because I had no priviliges to change the default memory limit on these servers I started looking for other sharpen functions. I have come across a php Unsharp Mask function which works like a charm on both of the servers I dealt with. It can be found at http://vikjavev.no/hovudsida/umtestside.php. ---- Manual Page -- http://www.php.net/manual/en/ref.image.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57909 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57909&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57909&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57909&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57909&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57909&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57909&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57909&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57909&report=yes Search -- http://master.php.net/manage/user-notes.php
