note 83292 added to function.imagecopyresampled

Here's a little function I wrote to resize images to a maximum dimension - based on what facebook does in the galleries. You put in a source, destination and a maximum dimension in pixels (eg 300), and for example if the image is long and thin, the longest edge will be 300px, yet the image retains proportions. A square image will become 300x300, a 6x4 (landscape) will become 300x200, a 4x6 (portrait) - 200x300 etc. It works on jpg images, but other formats can easily be added. <?php function createThumb($spath, $dpath, $maxd) { $src=@imagecreatefromjpeg($spath); if (!$src) {return false;} else { $srcw=imagesx($src); $srch=imagesy($src); if ($srcw<$srch) {$height=$maxd;$width=floor($srcw*$height/$srch);} else {$width=$maxd;$height=floor($srch*$width/$srcw);} if ($width>$srcw && $height>$srch) {$width=$srcw;$height=$srch;} //if image is actually smaller than you want, leave small (remove this line to resize anyway) $thumb=imagecreatetruecolor($width, $height); if ($height<100) {imagecopyresized($thumb, $src, 0, 0, 0, 0, $width, $height, imagesx($src), imagesy($src));} else {imagecopyresampled($thumb, $src, 0, 0, 0, 0, $width, $height, imagesx($src), imagesy($src));} imagejpeg($thumb, $dpath); return true; } } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 79.71.146.208 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- https://master.php.net/note/edit/83292 Del: integrated -- https://master.php.net/note/delete/83292/integrated Del: useless -- https://master.php.net/note/delete/83292/useless Del: bad code -- https://master.php.net/note/delete/83292/bad+code Del: spam -- https://master.php.net/note/delete/83292/spam Del: non-english -- https://master.php.net/note/delete/83292/non-english Del: in docs -- https://master.php.net/note/delete/83292/in+docs Del: other reasons-- https://master.php.net/note/delete/83292 Reject -- https://master.php.net/note/reject/83292 Search -- https://master.php.net/manage/user-notes.php
