Image resize and watermarking On The Fly.

[lopes_andre]

Hi all,

 

I'am trying to resize an image and watermarking in the same proccess using CodeIgniter, but without success, I'am able to do only one operation at the same time.

 

Because I'am not able to do it using CodeIgniter Image_lib... my question is:

 

It is possible to resize an image and watermarking On The Fly using GD library? If yes, do you know some examples?

 

 

Best Regards,

Here is some code I wrote a while back for the same feature.

 

Works like this:

 

script.php?src=yourimage.jpg

 

Then you can put that in an img html tag:

 

<img src="script.php?src=youimage.jpg"  />

 

<?php  
header('content-type: image/jpeg');  

$watermark = imagecreatefromgif('watermark.gif'); //your watermark image. 
$watermark_width = imagesx($watermark);  
$watermark_height = imagesy($watermark);  
$image = imagecreatetruecolor($watermark_width, $watermark_height);  
$image = imagecreatefromjpeg("imageuploads/".$_GET['src']);   // change to location of file. $get[src] is just the file name and extensions. e.g  filename.jpg 
$size = getimagesize("imageuploads/".$_GET['src']);  
$dest_x = $size[0] - $watermark_width - 5;  
$dest_y = $size[1] - $watermark_height - 5;  
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);  
imagejpeg($image);  
imagedestroy($image);  
imagedestroy($watermark);  
?>
