[php]Need help with resizejpeg

programming
1

Hi guys,
Spent the past couple of hours tinkering about with this function i got off the php docs.
The code works to a point. Am hoping someone can help me with this final step.
The main image that is resized appears to skew and distort.
What i need is if it does not meet max height or max width then either fill to max height and max or width or crop to.
i also need the same to happen to the thumbnail created.


/**********************************************************
 * function resizejpeg:
 *
 *  = creates a resized image based on the max width
 *    specified as well as generates a thumbnail from
 *    a rectangle cut from the middle of the image.
 *
 *    @dir  = directory image is stored in
 *    @img  = the image name
 *    @max_w = the max width of the resized image
 *    @max_h = the max height of the resized image
 *    @th_w  = the width of the thumbnail
 *    @th_h  = the height of the thumbnail
 *

function resizejpeg($dir, $img, $max_w, $max_h, $th_w, $th_h){
   // get original images width and height
   list($or_w, $or_h, $or_t) = getimagesize($dir.$img);
   // make sure image is a jpeg
   if ($or_t == 2) {
   
       // obtain the image's ratio
       $ratio = ($or_h / $or_w);
       // original image
       $or_image = imagecreatefromjpeg($dir.$img);
       // resize image
       if ($or_w > $max_w || $or_h > $max_h) {
           // first resize by width (less than $max_w)
           if ($or_w > $max_w) {
               $rs_w = $max_w;
               $rs_h = $ratio * $max_h;
