[SOLVED] Resizing a saved image using PHP

[waq2062]

Hi All,

 

I am uploading an image file using move_uploaded_file function. and once the image has been uploaded i want to give user an option to change its height and width so that user could change size of the image and then save it again.

 

Is it possible, can anyone help me out how can i do it.

 

Thanks

Heres a basic jpeg resize script.. you should be able to tweak this to suite your needs

 

<?php
// File and new size
$filename = 'test.jpg';
$percent = 0.5;

// Get new sizes
list($width, $height) = getimagesize($filename);
$newwidth = $width * $percent;
$newheight = $height * $percent;

// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);

// Resize
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

// Output
imagejpeg($thumb, $filename);
?>

Could someone explain me how can i integrate this script into my app. ? I want resizing image jpg file when output only. Size of image remain original but want to make it small when picture requested.
