note 55114 added to function.imagecreatefromstring

I run a blogging site that allowed users to publish images from their cell phones. For some reason, the nokia 3220 produces jpegs with extrandeous data before the EOF 0xFFF9 I wrote this class to allow you to fix the images so that they can be used with GD to resize and manipulate. Without applying the fix both GD and gimp report errors for the file. If basically keeps eating bytes from the junk part till the file is a valid jpeg. Here is an example bunk pic written by a nokia 3220 that you cna test it with http://www.shawnrider.com/moblog/cache/0854747001121624103.jpg /* Author: Paul Visco Hompage: http://www.elmwoodstrip.com?u=paul AIM: paulsidekick Notes: The file allows you fix the jpegs created by the Nokia 3220 picture phone so that they can be manipulated using the GD library with PHP. Usage: Simply instanitiate the class and then call the fix method for each image. e.g. $nokia = new nokia; $nokia->debug ="y"; $nokia->fix("yourpic.jpg"); */ class nokia { public $file; public $debug = "n"; public $dir_name = ""; private $img; //the image created from the string private $str; function fix($file) { //set the file to fix $this->file = $file; //load the file into a string $this->str = file_get_contents($this->file); //test to see if it is a nokia image or if it has been corrupted previously if (substr_count($this->str, chr(0x28).chr(0x36).chr(0x28).chr(0x2B)) == 0 || @imagecreatefromstring($this->str)) { if ($this->debug =="y") { echo "\n<br />".$this->file." is not a corrupted Nokia pic"; } return true; } //make a directory for fixed images if it doesn't exist and is specified if(!empty($this->dir_name) && !is_dir($this->dir_name)) { @mkdir($this->dir_name, 0777); } //strip out the funk e crap from the file $this->eat($this->str); //write the file back to itself file_put_contents($this->dir_name.$this->file, $this->str); //return true for fixed return true; } function eat() { //check the image $this->img = @imagecreatefromstring($this->str); //if the image doesn't work then keep striping out crap while(!$this->img) { //cut off the bad bytes one by one $this->str= substr_replace($this->str, "", -3, -2); //check the image again $this->img = @imagecreatefromstring($this->str); } if ($this->debug =="y") { //notify the user it's fixed echo "\n<br />Nasty bits eaten!! ".$this->file." is fixed now thanks to p:labs!"; } return true; } } ---- Manual Page -- http://www.php.net/manual/en/function.imagecreatefromstring.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55114 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55114&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55114&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55114&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55114&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55114&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55114&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55114&report=yes Search -- http://master.php.net/manage/user-notes.php
