#29878 [Bgs]: ImageCreateFromJpeg returns 'not a valid jpeg file'

ID: 29878 Updated by: derick@php.net Reported By: cyleriggs at kc dot rr dot com Status: Bogus Bug Type: GD related Operating System: Linux 2.6.8.1 PHP Version: 5.0.1 Assigned To: pajoye New Comment: Corrupted files are invalid, and may crash an application if attempted to use. That's why we will not implement that. (Actually, it's not a PHP issue either, it has to do with how libgd handles opening files). Previous Comments: ------------------------------------------------------------------------ [2004-10-07 03:18:23] cyleriggs at kc dot rr dot com Okay, so how about a feature suggestion than, i think that there should be the option in GD that allows you to try and open images that have a few corrupted bytes. If other programs can open them just fine what would be the harm in allowing programmers to choose to live with the corruptions? ------------------------------------------------------------------------ [2004-10-05 09:33:47] derick@php.net PHP only reads non-coprrupted files - there is no bug here. ------------------------------------------------------------------------ [2004-10-05 04:34:39] cyleriggs at kc dot rr dot com After playing around with the images themselves i have found that converting them from jpeg to png then back to jpeg fixed the problem and yielded no quality loss. I used the linux tool set called ImageMagick to do this. I wrote a short perl script to go through all my images and fix them. Other than this i have found no other way of stopping this. one interesting fact though is that while converting the images with the imagemagick utility it complained about some corruptions, however it was still able to open them fine and convert them. Maybe PHP is being too picky about the images that it opens as despite a few corrupted bytes EVERYthing was able to open these images except for PHP. ------------------------------------------------------------------------ [2004-09-30 21:05:50] paul at gslip dot com I disagree. I have used my code successfully on montypics.com until the upgrade to php 5.0.1. I now get exactly the same results as the original poster. Images that worked fine on previous versions now do not. I have a sample image that can be provided. I also have code I can share with the PHP team although I cannot post it here as it is lengthy and copyrighted. ------------------------------------------------------------------------ [2004-08-29 12:22:14] pajoye@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. Your jpeg file is not valid. PHP could not take care of each possible failures in image files. Desktop softwares could. Fix your image and replace it. --Pierre ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
