note 72581 added to function.imageinterlace

It was suggested that this function can be used to retrieve the interlace bit of an image that is stored in a file. This is not the case. While imageinterlace() returns 0 or 1 if a valid Image resource is passed, passing a file name as a string results in a PHP warning and the return value is neither 0 nor 1. ---- Server IP: 216.194.113.175 Probable Submitter: 216.123.202.72 ---- Manual Page -- http://www.php.net/manual/en/function.imageinterlace.php Edit -- https://master.php.net/note/edit/72581 Del: integrated -- https://master.php.net/note/delete/72581/integrated Del: useless -- https://master.php.net/note/delete/72581/useless Del: bad code -- https://master.php.net/note/delete/72581/bad+code Del: spam -- https://master.php.net/note/delete/72581/spam Del: non-english -- https://master.php.net/note/delete/72581/non-english Del: in docs -- https://master.php.net/note/delete/72581/in+docs Del: other reasons-- https://master.php.net/note/delete/72581 Reject -- https://master.php.net/note/reject/72581 Search -- https://master.php.net/manage/user-notes.php
