Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Hello, Cannot reproduce, please try with a snapshot. I also use libpng-1.2.2 (which is available since this week through yum in fdc1). --Pierre Previous Comments: ------------------------------------------------------------------------ [2004-05-07 03:01:51] Rich dot West at wesmo dot com What version of libpng did you back down to? I have no problems trying that out. :) ------------------------------------------------------------------------ [2004-05-07 00:58:29] scottmacvicar at ntlworld dot com I had the same problem using the latest releases of libpng and had to go back to an older version. It would happen for any png image. Was using Red Hat Enterprise ------------------------------------------------------------------------ [2004-05-06 16:54:14] Rich dot West at wesmo dot com Any PNG image will do it. I woul attach it, but there's no interface here to attach the images that I tested with. ------------------------------------------------------------------------ [2004-05-06 14:40:31] [EMAIL PROTECTED] Please provide the source image. ------------------------------------------------------------------------ [2004-05-03 19:22:22] Rich dot West at wesmo dot com Description: ------------ After upgrading from PHP 4.3.3 to 4.3.5, and then again to 4.3.6, I discovered that image generation calls to create PNG files were producing zero length images. I dug through it further by testing with the CLI version of PHP, and it appears that if a PNG image is being created, the process with segfault. I was able to compile PHP 4.3.3 on this machine using the configure options below, and, after running the test script through php, it would properly output a PNG file. Using the same configure options for PHP 4.3.5 and PHP 4.3.6, the operation segfaults (and creates a core file) when creating a PNG file. It works just fine when creating a JPEG file. I can consistently get things to work for PHP 4.3.3 and I can consistently get it to NOT work for PHP 4.3.5 and PHP 4.3.6... Oh, and, yes, my GD and libpng10/libpng libraries are linked properly.. >From phpinfo(): './configure' '--host=i686-pc-linux-gnu' '--build=i686-pc-linux-gnu' '--target=i386-redhat-linux-gnu' '--program-prefix=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--sysconfdir=/etc' '--datadir=/usr/share' '--includedir=/usr/include' '--libdir=/usr/lib' '--libexecdir=/usr/libexec' '--localstatedir=/var' '--sharedstatedir=/usr/com' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--cache-file=../config.cache' '--with-config-file-path=/etc' '--with-config-file-scan-dir=/etc/php.d' '--enable-force-cgi-redirect' '--disable-debug' '--enable-pic' '--disable-rpath' '--enable-inline-optimization' '--with-bz2' '--with-db4=/usr' '--with-curl' '--with-exec-dir=/usr/bin' '--with-freetype-dir=/usr' '--with-png-dir=/usr' '--with-gd' '--enable-gd-native-ttf' '--with-gdbm' '--with-gettext' '--with-ncurses' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-png' '--with-pspell' '--with-regex=system' '--with-xml' '--with-expat-dir=/usr' '--with-dom=shared,/usr' '--with-dom-xslt=/usr' '--with-dom-exslt=/usr' '--with-xmlrpc=shared' '--with-pcre=/usr' '--with-zlib' '--with-layout=GNU' '--enable-bcmath' '--enable-exif' '--enable-ftp' '--enable-magic-quotes' '--enable-safe-mode' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-discard-path' '--enable-track-vars' '--enable-trans-sid' '--enable-yp' '--enable-wddx' '--without-oci8' '--with-pear=/usr/share/pear' '--with-imap=shared' '--with-imap-ssl' '--with-kerberos' '--with-ldap=shared' '--with-pdflib' '--with-mysql=shared,/usr' '--with-pgsql=shared' '--with-snmp=shared,/usr' '--with-snmp=shared' '--enable-ucd-snmp-hack' '--with-unixODBC=shared' '--enable-memory-limit' '--enable-bcmath' '--enable-shmop' '--enable-calendar' '--enable-dbx' '--enable-dio' '--enable-mcal' '--enable-mbstring' '--enable-mbstr-enc-trans' '--enable-mbregex' '--with-apxs2=/usr/sbin/apxs' Reproduce code: --------------- <?php header("Content-type: image/png"); $string = "Test"; $im = imagecreatefrompng("image.png"); $orange = imagecolorallocate($im, 220, 210, 60); $px = (imagesx($im) - 7.5 * strlen($string)) / 2; imagestring($im, 3, $px, 9, $string, $orange); imagepng($im); imagedestroy($im); ?> Expected result: ---------------- Result should have been a PNG image.
