Image Resizing

[melloorr]

Hey everyone. I have been trying to make a script that allows me to resize an image but I am having some trouble. I have got a script that takes  an image and resize's it:

<?php 
$save = $_REQUEST['SavedAs'] ;
$file = $_REQUEST['ImgAdd'] ;
echo "Creating file: $save"; 
$size = 0.45; 
header('Content-type: image/jpeg') ; 
list($width, $height) = getimagesize($file) ; 
$modwidth = 240; 
$modheight = 180; 
$tn = imagecreatetruecolor($modwidth, $modheight) ; 
$image = imagecreatefromjpeg($file) ; 
imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; 

imagejpeg($tn, $save, 100) ; 

header ("Location: $save");
?> 

 

But depending on the image, the aspect ratio looks wrong. Is there anyway to take an image, crop it, then resize it? Or something that makes it look decent?

 

Thanks

Hi

 

There's an awesome way to do it:

I use this script on my websites.

Is this the only way to do it? Because I would rather crop it first then resize it, if possible.

Okay so I have now got code that crops it, then resizes it, but is still does not look right, is there any way to get it to start at the top of the picture, but in the middle width wise? (as it normally starts in the top left corner, then 720px out to the right) Here is my code so far:

<?php

$image = $_REQUEST['Img']; // the image to crop
$dest_image = $_REQUEST['Saved']; // make sure the directory is writeable

$img = imagecreatetruecolor('720','540');
$org_img = imagecreatefromjpeg($image);
$ims = getimagesize($image);
imagecopy($img,$org_img, 0, 0, 20, 20, 720, 540);
imagejpeg($img,$dest_image,90);
imagedestroy($img);

$save = $_REQUEST['Saved'] ;
$file = $dest_image ;
echo "Creating file: $save"; 
$size = 0.3333333333333333333333333333333333333333333; 
header('Content-type: image/jpeg') ; 
list($width, $height) = getimagesize($file) ; 
$modwidth = $width * $size; 
$modheight = $height * $size; 
$tn = imagecreatetruecolor($modwidth, $modheight) ; 
$image = imagecreatefromjpeg($file) ; 
imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; 

imagejpeg($tn, $save, 100) ; 

header ("Location: $save");

?>
