Image resizing

[kesaven]

we have a website running prestashop version:

 

the following code is in a class called annonce.php

 

$newwidth = 45;
$newheight = round($height * $newwidth / $width);
                        $tmp=imagecreatetruecolor($newwidth,$newheight);
                        $white = imagecolorallocate($tmp, 255, 255, 255);
         imagefilledrectangle($tmp, 0, 0, $newwidth, $newheight, $white);


$newwidth1 = 400;
$newheight1 = round($height * $newwidth1 / $width);
                        $tmp1=imagecreatetruecolor($newwidth1,$newheight1);
$white = imagecolorallocate($tmp1, 255, 255, 255);
         imagefilledrectangle($tmp1, 0, 0, $newwidth1, $newheight1, $white);

                        $newwidth2 = 430;
$newheight2 = round($height * $newwidth2 / $width);
                        $tmp2=imagecreatetruecolor($newwidth2,$newheight2);
$white = imagecolorallocate($tmp2, 255, 255, 255);
         imagefilledrectangle($tmp2, 0, 0, $newwidth2, $newheight2, $white);

                        $newwidth3 = 600;
$newheight3 = round($height * $newwidth3 / $width);
                        $tmp3=imagecreatetruecolor($newwidth3,$newheight3);
$white = imagecolorallocate($tmp3, 255, 255, 255);
         imagefilledrectangle($tmp3, 0, 0, $newwidth3, $newheight3, $white);

                        $newwidth4 = 183;
$newheight4 = round($height * $newwidth4 / $width);
                        $tmp4=imagecreatetruecolor($newwidth4,$newheight4);
$white = imagecolorallocate($tmp4, 255, 255, 255);
         imagefilledrectangle($tmp4, 0, 0, $newwidth4, $newheight4, $white);
                                
     imagecopyresampled($tmp, $src, (int)(($newwidth - $newwidth) / 2), (int)(($newheight - $newheight) / 2), 0, 0, $newwidth, $newheight, $width, $height);
                        imagecopyresampled($tmp1, $src, (int)(($newwidth1 - $newwidth1) / 2), (int)(($newheight1 - $newheight1) / 2), 0, 0, $newwidth1, $newheight1, $width, $height);
imagecopyresampled($tmp2, $src, (int)(($newwidth2 - $newwidth2) / 2), (int)(($newheight2 - $newheight2) / 2), 0, 0, $newwidth2, $newheight2, $width, $height);
imagecopyresampled($tmp3, $src, (int)(($newwidth3 - $newwidth3) / 2), (int)(($newheight3 - $newheight3) / 2), 0, 0, $newwidth3, $newheight3, $width, $height);
imagecopyresampled($tmp4, $src, (int)(($newwidth4 - $newwidth4) / 2), (int)(($newheight4 - $newheight4) / 2), 0, 0, $newwidth4, $newheight4, $width, $height);

                        $filename = "img/p/".$id_product."-".$id_image."-small.jpg"; //45/45

                        imagejpeg($tmp,$filename,100);

It is used to resize an uploaded in different sizes to fit different views

This function code is not working

 

However when we upload an image from the backoffice, it is always correctly resized and placed in a white box and is not distorted.

 

can anyone please help?

In fact I need small images to remain the same except that it is put in a white background box of fixed size and that larger images are resized correctly.
