note 85711 added to function.imagejpeg

For those looking to grab the resolution of a JPEG image without using GD nor ImageMagic... I wrote this simple function. Too bad GD doesn't have this very simple function for us to use... <?php function getJPEGresolution($filename){ $outRez=array(); // Read the file ob_start(); // start a new output buffer $image = file_get_contents($filename); // grab DPI information from the JPG header $outRez["xDPI"] = ord($image[15]); $outRez["yDPI"] = ord($image[17]); ob_end_clean(); // stop this output buffer //xDPI and yDPI should equal in value... but we output both anyway... return($outRez); }//end function getJPEGresolution ?> ---- Server IP: 61.195.146.164 Probable Submitter: 124.85.118.11 ---- Manual Page -- http://www.php.net/manual/en/function.imagejpeg.php Edit -- https://master.php.net/note/edit/85711 Del: integrated -- https://master.php.net/note/delete/85711/integrated Del: useless -- https://master.php.net/note/delete/85711/useless Del: bad code -- https://master.php.net/note/delete/85711/bad+code Del: spam -- https://master.php.net/note/delete/85711/spam Del: non-english -- https://master.php.net/note/delete/85711/non-english Del: in docs -- https://master.php.net/note/delete/85711/in+docs Del: other reasons-- https://master.php.net/note/delete/85711 Reject -- https://master.php.net/note/reject/85711 Search -- https://master.php.net/manage/user-notes.php
