note 50432 added to function.imagecopyresized

Most of the examples below don't keep the proportions properly. They keep using if/else for the height/width..and forgetting that you might have a max height AND a max width, not one or the other. /** * Resize an image and keep the proportions * @author Allison Beckwith <allison@planetargon.com> * @param string $filename * @param integer $max_width * @param integer $max_height * @return image */ function resizeImage($filename, $max_width, $max_height) { list($orig_width, $orig_height) = getimagesize($filename); $width = $orig_width; $height = $orig_height; # taller if ($height > $max_height) { $width = ($max_height / $height) * $width; $height = $max_height; } # wider if ($width > $max_width) { $height = ($max_width / $width) * $height; $width = $max_width; } $image_p = imagecreatetruecolor($width, $height); $image = imagecreatefromjpeg($filename); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $orig_width, $orig_height); return $image_p; } ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresized.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50432 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50432&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50432&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50432&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50432&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50432&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50432&report=yes Search -- http://master.php.net/manage/user-notes.php
