the first function to resize the image on the page is faulty this is a better function that works and also has a second pass because some images did not get trough properly in the first pass function resizeImage($src, $w, $h) { // Get the current size $width = ImageSx($src); $height = ImageSy($src); // If one dimension is right then nothing to do // if($width <= $w || $height <= $h) // return($src); // Calculate new size if(($w - $width) > ($h - $height)) { // use height $s = $h / $height; $nw = round($width * $s); $nh = round($height * $s); } else { // Use width $s = $w / $width; $nw = round($width * $s); $nh = round($height * $s); } // Return the new image $nwidth = $nw; $nheight = $nh; // If one dimension is right then nothing to do // if($width <= $w || $height <= $h) // return($src); // Calculate new size if(($w - $nwidth) > ($h - $nheight)) { // use height $s = $h / $nheight; $nw = round($nwidth * $s); $nh = round($nheight * $s); } else { // Use width $s = $w / $nwidth; $nw = round($nwidth * $s); $nh = round($nheight * $s); } $im = ImageCreateTrueColor($nw, $nh); ImageCopyResampled($im, $src, 0, 0, 0, 0, $nw, $nh, $width, $height); return($im); } ---- Server IP: 69.147.83.197 Probable Submitter: 86.106.49.77 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- https://master.php.net/note/edit/102746 Del: integrated -- https://master.php.net/note/delete/102746/integrated Del: useless -- https://master.php.net/note/delete/102746/useless Del: bad code -- https://master.php.net/note/delete/102746/bad+code Del: spam -- https://master.php.net/note/delete/102746/spam Del: non-english -- https://master.php.net/note/delete/102746/non-english Del: in docs -- https://master.php.net/note/delete/102746/in+docs Del: other reasons-- https://master.php.net/note/delete/102746 Reject -- https://master.php.net/note/reject/102746 Search -- https://master.php.net/manage/user-notes.php
