ID: 35348 Updated by: pajoye@php.net Reported By: dtra at faceyoursfears dot com -Status: Feedback +Status: Bogus Bug Type: GD related Operating System: fedora core 4 linux PHP Version: 5.1.0RC6 -Assigned To: +Assigned To: pajoye New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. No matter the size it is a memory limit problem ('--enable-memory-limit'), increase the max values or does not use it if you do not know what it does. --Pierre Previous Comments: ------------------------------------------------------------------------ [2005-11-23 12:37:30] tony2001@php.net How big is this image (Screenshot.png)? ------------------------------------------------------------------------ [2005-11-23 12:31:21] dtra at faceyoursfears dot com sorry, it says line 5 in the error output, it's the line that says $i = imagecreatefrompng($file); ------------------------------------------------------------------------ [2005-11-23 12:28:28] dtra at faceyoursfears dot com Description: ------------ i am just trying to resize an image on my computer, using the gd library, imagecreatefrompng gives me this errorFatal i have 777 chmodded all directories and files gd is the bundled gd library installed as a shared module imagecreatefromjpeg, using exactly the same code works fine './configure' '--build=i386-redhat-linux' '--host=i386-redhat-linux' '--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-libdir=lib' '--with-config-file-path=/etc' '--with-config-file-scan-dir=/etc/php.d' '--disable-debug' '--with-pic' '--disable-rpath' '--with-bz2' '--with-curl' '--with-exec-dir=/usr/bin' '--with-freetype-dir=/usr' '--with-png-dir=/usr' '--enable-gd-native-ttf' '--without-gdbm' '--with-gettext' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-png' '--with-expat-dir=/usr' '--with-pcre-regex=/usr' '--with-zlib' '--with-layout=GNU' '--enable-exif' '--enable-ftp' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-sysvmsg' '--enable-track-vars' '--enable-trans-sid' '--enable-yp' '--enable-wddx' '--with-pear=/usr/share/pear' '--with-kerberos' '--enable-ucd-snmp-hack' '--with-unixODBC=shared,/usr' '--enable-memory-limit' '--enable-shmop' '--enable-calendar' '--enable-dbx' '--enable-dio' '--with-mime-magic=/etc/httpd/conf/magic' '--without-sqlite' '--with-libxml-dir=/usr' '--with-xml' '--with-apxs2=/usr/sbin/apxs' '--without-mysql' '--without-gd' '--without-odbc' '--disable-dom' '--disable-dba' '--without-mysqli' additional ini files parsed /etc/php.d/dom.ini, /etc/php.d/ffmpeg.ini, /etc/php.d/gd.ini, /etc/php.d/mysql.ini, /etc/php.d/mysqli.ini, /etc/php.d/pdo.ini, /etc/php.d/pdo_mysql.ini, /etc/php.d/soap.ini, /etc/php.d/xsl.ini ----added to php.ini------- [mime_magic] mime_magic.debug = 1 mime_magic.magicfile = "/usr/share/file/magic.mime" Reproduce code: --------------- $file = '/path/to/Screenshot.png'; $path = '/var/www/html/images/temp.png'; $type = mime_content_type($file); $i = imagecreatefrompng($file); list($width, $height) = getimagesize($file); if ($width > $height) $scale = $width / 260; else $scale = $height / 240; $imgWidth = round($width/$scale, 0); $imgHeight = round($height/$scale, 0); $newI = imagecreatetruecolor($imgWidth, $imgHeight); $bgColor = imagecolorallocate($newI, 51, 85, 204); imagefilledrectangle($newI, 0, 0, $imgWidth, $imgHeight, $bgColor); imagecopyresampled($newI, $i, 0, 0, 0, 0, $imgWidth, $imgHeight, $width, $height); if ($type == 'image/jpeg') imagejpeg($finalImg, $path, 70); else if ($type == 'image/x-png' || $type == 'image/png') imagepng($finalImg, $path, 70); header('Content-type: image/png'); imagepng($path); Expected result: ---------------- prints the newly resized and created image to the screen Actual result: -------------- error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 5242880 bytes) in /var/www/html/tmp/png-img.php on line 5 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35348&edit=1
