Edit report at http://bugs.php.net/bug.php?id=54482&edit=1 ID: 54482 Updated by: pajoye@php.net Reported by: info822 at freshsoftware dot net Summary: imagecreatefromstring fails -Status: Open +Status: Feedback Type: Bug Package: GD related Operating System: Fedora 13 (Godard) Kernel Linux PHP Version: 5.3.6 -Assigned To: +Assigned To: pajoye Block user comment: N Private report: N New Comment: Well, as I said, the code works. If for some reason it does not work on another server, then you have to verify its configuration. Have you tried my example on the dev server? Or any other where you met this bug? Previous Comments: ------------------------------------------------------------------------ [2011-04-07 22:52:08] info822 at freshsoftware dot net file_get_contents is apparently not reading the entire file. ------------------------------------------------------------------------ [2011-04-07 22:48:29] info822 at freshsoftware dot net You couldnot reporduce the error because you apparently only looked at the live server. Please look at the DEV server. http://thewordsmith.dyndns.info/resize_event_pic.php?event_num=27&new_width=100&new_height=143 ------------------------------------------------------------------------ [2011-04-07 21:59:38] pajoye@php.net Cannot reproduce. Here is a simple script: <?php $file = 'https://secure20.nexcess.net/thewordsmith.info/images/event_images/2010-11- 20/The%20Lake%20Effect%20Festival/Lake%20Effect%20Hip%20Hop%20Flyer.jpg'; imagepng(imagecreatefromjpeg($file), 'a1.png'); imagepng(imagecreatefromstring(file_get_contents($file)), 'a2.png'); a1 and a2 are just fine. Please try this script as well. ------------------------------------------------------------------------ [2011-04-07 17:52:54] info822 at freshsoftware dot net A list off all the rpms installed on my system can be viewed at: http://thewordsmith.dyndns.info/rpms_installed.txt ------------------------------------------------------------------------ [2011-04-07 06:53:18] info822 at freshsoftware dot net Description: ------------ I am writing you because "imagecreatefromstring" is causing images to output black images. I have been using the same script on a live server running CentOS/PHP-5.1.6 and a development server running Fedora 9/PHP-5.2.3 for 1+ year with no problem. Recently I upgraded the dev server to Fedora 13/PHP-5.3.6 and now the same script has stopped displaying images. I have recompiled PHP, reinstalled http, httpd-devel, gd, gd-devel, libjpeg, libjpeg-devel, libpng, libpng-devel, and other related packages numerous times. But I can not figure out the problem. I would install PHP-5.2.3 on Fedora 13 but Openssl error out during the make process. ****************************************************************************** Here is some information about the liver server that does not have a problem. phpinfo: https://secure20.nexcess.net/thewordsmith.info/php/ Script View: https://secure20.nexcess.net/thewordsmith.info/resize_event_pic.php?event_num=27&new_width=100&new_height=143 Actual Image: https://secure20.nexcess.net/thewordsmith.info/images/event_images/2010-11-20/The%20Lake%20Effect%20Festival/Lake%20Effect%20Hip%20Hop%20Flyer.jpg Product script View: https://secure20.nexcess.net/thewordsmith.info/calendar.php ****************************************************************************** Here is info about the development server with the "imagecreatefromstring" problem: phpinfo: http://thewordsmith.dyndns.info/php/ Script View: http://thewordsmith.dyndns.info/resize_event_pic.php?event_num=27&new_width=100&new_height=143 Actual image: http://thewordsmith.dyndns.info/images/event_images/2010-11-20/The%20Lake%20Effect%20Festival/Lake%20Effect%20Hip%20Hop%20Flyer.jpg Production Script View: http://thewordsmith.dyndns.info/calendar.php ****************************************************************************** The logs are putting out "chunk" and "Corrupt JPEG data: 18580 extraneous bytes before marker 0xe2" errors.
