From: [EMAIL PROTECTED] Operating system: Darwin 6.1 (Mac 10.2.1) PHP version: 4CVS-2002-10-08 PHP Bug Type: GD related Bug description: ImageCreateFromGD2() doesnt recognize uncompressed .gd2 images
ImageCreateFromGD2() does not recognize a uncompressed gd2 file. It seems to work just fine with compressed GD2 files, but I am having problems compressing a GD2 file of mine. (pngtogd2 gives a "Bus error" when I try to compress, not a PHP problem tho) This script: <?php header( "Content-type: image/png" ); $medimg = $_SERVER['DOCUMENT_ROOT'] . "/riverdata/images/ world_map_med.gd2"; $medimg = ImageCreateFromGD2Part( $medimg, $x, $y, 800, 600 ); $img = ImageCreateTrueColor( 800, 600 ); ImageCopy( $img, $medimg, 0, 0, 0, 0, 800, 600 ); ImageDestroy( $medimg ); ImagePNG( $img ); ImageDestroy( $img ); ?> Leaves this in the error log: [Tue Oct 8 09:25:50 2002] [error] PHP Warning: imagecreatefromgd2part() [<a href='http://www.php.net/ function.imagecreatefromgd2part'> function.imagecreatefromgd2part</a>]: '/Library/WebServer/ Documents/riverdata/images/world_map_med.gd2' is not a valid GD2 file in /Library/WebServer/Documents/riverdata/ scripts/test.php on line 3 [Tue Oct 8 09:25:50 2002] [error] PHP Warning: imagecopy(): supplied argument is not a valid Image resource in /Library/WebServer/Documents/riverdata/scripts/ test.php on line 4 [Tue Oct 8 09:25:50 2002] [error] PHP Warning: imagedestroy(): supplied argument is not a valid Image resource in /Library/WebServer/Documents/riverdata/scripts/ test.php on line 4 The error occours when I use this command to create the GD2 file: % /usr/local/bin/pngtogd2 world_map_med.png world_map_med.gd2 800 1 and doesn't when I use this: % /usr/local/bin/pngtogd2 world_map_med.png world_map_med.gd2 800 2 Usage: pngtogd2 filename.png filename.gd2 cs fmt where cs is the chunk size fmt is 1 for raw, 2 for compressed The files that I am using can be found here: http://144.92.10.251/riverdata/images/ Keep in mind tho that I have no way of telling that a valid GD2 file is being created in the first place because I know of nothing else that uses (or creates) the GD2 file format other than the GD library itself. -- Edit bug report at http://bugs.php.net/?id=19817&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19817&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19817&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19817&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19817&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19817&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=19817&r=support Expected behavior: http://bugs.php.net/fix.php?id=19817&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=19817&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=19817&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19817&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=19817&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=19817&r=dst IIS Stability: http://bugs.php.net/fix.php?id=19817&r=isapi
