Barand Posted March 31, 2007 Share Posted March 31, 2007 1 ) Have you now downloaded the php_gd2.dll file from php.net? 2 ) Have you looked in you php.ini file for the line extension_dir = xxxx 3 ) Have you put the .dll file in the folder xxxx as defined in the ini file. 4 ) Have you then looked in the php.ini file for the line ;extension=php_gd2.dll and removed the ; from the beginning. When you have, let us know. I know this may sound familiar as I answered this here http://www.phpfreaks.com/forums/index.php/topic,133944.msg563734.html#msg563734 Link to comment https://forums.phpfreaks.com/topic/45075-solved-gd-configuration/#findComment-218857 Share on other sites More sharing options...

ali_2kool2002 Posted April 1, 2007 Author Share Posted April 1, 2007 every time i look for a library on php.net it says its moved to another link and when i click the link it goes to http://www.libgd.org/Main_Page.. this is where i dowloaded the file gd-2.0.35RC1.tar.bz2 which has no dll file.. any further ideas ?thanks another good site is http://www.maani.us/charts/index.php but the chart doesnt change when i follow its tutorial, is this because it requires GD aswel?

Barand Posted April 1, 2007 Share Posted April 1, 2007 This version should stop those notices when no values are passed to the script. <?php // set dimensions $w = 102; $h = 12; // create image $im = imagecreate($w, $h); // set colours to be used $bg = imagecolorallocate($im, 0xE0, 0xE0, 0xE0); $black = imagecolorallocate($im, 0x00, 0x00, 0x00); $barcolor = imagecolorallocate($im, 0xFF, 0x00, 0x00); // draw border imagerectangle($im, 0,0,$w-1,$h-1,$black); // get value and max value from query string $val = isset($_GET['val']) ? $_GET['val'] : 0; $max = isset($_GET['max']) ? $_GET['max'] : 100; // calculate dimensions of inner bar $barw = $max ? floor(($w-2) * $val / $max) : 0; $barh = $h - 2; // draw inner bar if ($barw) imagefilledrectangle($im, 1, 1, $barw, $barh, $barcolor); // send image header header("content-type: image/png"); // send png image imagepng($im); imagedestroy($im); ?> Link to comment https://forums.phpfreaks.com/topic/45075-solved-gd-configuration/#findComment-219083 Share on other sites More sharing options...

Barand Posted April 1, 2007 Share Posted April 1, 2007 png support is built in to the gd extension If you run <?php phpinfo(); ?> You will get a list of supported formats. When I run the sample html I get the attachd image. If I run bar.php on its own with no query string I get a grey rectangle [attachment deleted by admin] Link to comment https://forums.phpfreaks.com/topic/45075-solved-gd-configuration/#findComment-219111 Share on other sites More sharing options...

Barand Posted April 1, 2007 Share Posted April 1, 2007 P.S. REMOVING THE SURROUND CODE DID THE JOB....wonder why it didnt work with it... Placing a gd produced image with < img src='an_image.php' > is the same as placing a static image file (such as jpeg). The only diff is the image is generated on demand from the php code. If you edited a jpeg file and put the html code at the begining and end then that wouldn't work either.
