#19817 [Fbk->Opn]: ImageCreateFromGD2() doesnt recognize uncompressed .gd2 images

ID: 19817 User updated by: sprice@wisc.edu Reported By: sprice@wisc.edu -Status: Feedback +Status: Open Bug Type: Feature/Change Request Operating System: Darwin 6.1 (Mac 10.2.1) PHP Version: 4CVS-2002-10-08 New Comment: Nope, it still dosen't work with either compressed or uncompressed images. I am using GD 2.0.11 to produce the GD2 images. You guys should sync up with the current GD so I can try using it, instead.

As far as I know nobody is working on it. I certainly don't need this functionality. Feel free to submit a patch. ------------------------------------------------------------------------ [2002-10-29 21:38:19] sprice@wisc.edu Problem still exists using latest CVS snap and GD 2.0.4. (I thought I would mention it 'cause I have seen lots of GD work being done in both.) ------------------------------------------------------------------------ [2002-10-19 21:06:21] sprice@wisc.edu FYI: this bug still exists in the latest CVS snapshot. ------------------------------------------------------------------------ [2002-10-11 06:15:54] mfischer@php.net Did test http://144.92.10.251/riverdata/images/uncompressed_med.gd2 and got the following: $ php 19817.php Error from seek: 25 Warning: imagecreatefromgd2part() [http://www.php.net/function.imagecreatefromgd2part]: 'uncompressed_med.gd2' is not a valid GD2 file in /home/mfischer/src/php/bugs/gd/19817.php on line 7 /home/mfischer/src/php/bugs/gd/19817.php(7) : Warning - imagecreatefromgd2part() [http://www.php.net/function.imagecreatefromgd2part]: 'uncompressed_med.gd2' is not a valid GD2 file Warning: imagecopy(): supplied argument is not a valid Image resource in /home/mfischer/src/php/bugs/gd/19817.php on line 10 /home/mfischer/src/php/bugs/gd/19817.php(10) : Warning - imagecopy(): supplied argument is not a valid Image resource Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/mfischer/src/php/bugs/gd/19817.php on line 11 /home/mfischer/src/php/bugs/gd/19817.php(11) : Warning - imagedestroy(): supplied argument is not a valid Image resource PNG IHDR vpkIDATxí×1 À°Ïà¢$ [binary scumm] The interesting thing I think is "Error from seek: 25" which actually comes from the bundled libgd from libgd/gd_gd2.c from gdImageCreateFromGd2PartCtx, line 584: if (gdSeek (in, dpos) != 0) { printf ("Error from seek: %d\n", errno); goto fail2; }; Error code 25 means "Inappropriate ioctl for device", no idea why this happens though. Maybe a problem related from mixing PHP Streams and native access to FILE fd's ? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
