 Posted: Thu May 29, 2003 11:39 am Post subject: seg fault using perl GD module |
 |
|
When trying to create a new GD image from an existing file I get a segmentation fault. I've tried various constructors and image formats, but always the same error.
| Code: | #!/usr/bin/perl -w
use strict;
use GD;
open IN, 'image.jpg' or die "Could not open.";
my $srcImage = GD::Image->newFromJpeg(*IN);
close IN;
my $srcImage2 = GD::Image->newFromJpeg('image.jpg');
my $srcImage3 = GD::Image->new('image.png');
|
I used strace but do not know enough to make use of the output. The last (hopefully pertinent) lines are:
| Code: | open("image.png", O_RDONLY|O_LARGEFILE) = 3
ioctl(3, SNDCTL_TMR_TIMEBASE, 0xbffff0d0) = -1 EINVAL (Invalid argument)
_llseek(3, 0, [0], SEEK_CUR) = 0
fstat64(3, {st_mode=S_IFREG|0744, st_size=4234, ...}) = 0
fcntl64(3, F_SETFD, FD_CLOEXEC) = 0
read(3, "\211PNG\r\n\32\n\0\0\0\rIHDR\0\0\0@\0\0\0@\10\3\0\0\0\235"..., 4096) = 4096
_llseek(3, 4, [4], SEEK_SET) = 0
_llseek(3, 0, [4], SEEK_CUR) = 0
_llseek(3, 0, [0], SEEK_SET) = 0
_llseek(3, 0, [0], SEEK_CUR) = 0
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

I'm using
libgd-1.8.3-r6
GD-1.32-r3
perl-5.8.0-r10
Any help would be much appreciated.
thx |

I just tried php as it also uses GD to manipulate images. I tried a simple php script.
| Code: |
$filename=$argv[1];
$thumb_file=$argv[2];
$src_img = imagecreatefromjpeg($filename);
$dst_img = imagecreate(80,60);
imagecopyresized($dst_img, $src_img, 0, 0, 0, 0, 80, 60, 320, 240);
imagejpeg($dst_img,$thumb_file,75);
imagedestroy($src_img);
imagedestroy($dst_img);
|
this runs ok, but the reultant images are high contrast and under saturated. This script, run on my debian box, produces colour jpegs fine.
Is there something wrong with libgd by any chance? |
