ID: 13323 Updated by: mfischer Reported By: marc_thomas@hotmail.com Old Status: Open Status: Feedback Bug Type: *Graphics related Operating System: Windows 2000 Pro PHP Version: 4.0.6 New Comment: Please try a recent snapshot from http://snaps.php.net:8000/ - Markus Previous Comments: ------------------------------------------------------------------------ [2001-09-15 19:35:05] marc_thomas@hotmail.com Image produced by FujiFilm 4900Zoom Examples of error messages. The number of bytes in the error messages varies from image to image. With an image taken at 640x480 I get error: Fatal error: Illegal thumbnail size in E:\MyFiles\web\rucc\oldtest.php on line 12 With an image taken at 1280x960 I get error: FATAL: emalloc(): Unable to allocate -266076160 bytes With an image taken at 1600x1200 I get error: FATAL: emalloc(): Unable to allocate -1222377472 bytes With an image taken at 2400x1800 I get error: FATAL: emalloc(): Unable to allocate -500891648 bytes It would appear that it is falling over in function 'ExtractThumbnail' that can be found in exif.c I have tried the same php script with an image taken by an Olympus camera and it works without problem. All the other Exif reading utilities I have work equally well with Olympus and Fuji images. Some sample images 640x480 - http://marct.com/DSCF0023.JPG 1280x960 - http://marct.com/DSCF0022.JPG 1600x1200 - http://marct.com/DSCF0021.JPG 2400x1800 - http://marct.com/DSCF0020.JPG Sample Script: <?php $exif = read_exif_data ('DSCF0023.JPG'); ?> I am using the pre-compiled version of PHP, 4.0.6 with IIS5. The only change I have made to the php.ini file it to un-comment the line 'extension=php_exif.dll' I would be of great benefit if I could use this php function with these images and will help in any way I can to fix the problem.
