note 48624 added to function.imagecopyresampled

This simple function resizes a JPG image file giving just a maximum width, and resizes keeping the aspect ratio. This is useful if you have to resize a JPG image that must fit the width of i.e. a div element, but doesn't have to have a maximum height. <? function resizeJPG($jpgFile, $width) { // Get new dimensions list($width_orig, $height_orig) = getimagesize($jpgFile); $height = (int) (($width / $width_orig) * $height_orig); // Resample $image_p = imagecreatetruecolor($width, $height); $image = imagecreatefromjpeg($jpgFile); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig); // Output imagejpeg($image_p, $jpgFile, 100); } ?> -Stu ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48624 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48624&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48624&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48624&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48624&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48624&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48624&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48624&report=yes Search -- http://master.php.net/manage/user-notes.php
