GD Image Library Question URL...

[rckehoe]

I have just a question....

 

1) Can the GD Image library get an image from a given URL and then resize it, then save it to my local server? The main question would be, does it support the URL passing, or does the image have to be local?

if gd itself can't, look into curl.

 

Try feeding an url though, a lot of functions work quite fine with it (when server settings allow it)

curl cannot resize an image, can it?

The whole point of what I am doing is to be able to resize the image, then save it on the server, so I don't have to download the image, then resize, then re-save it back to the server and delete the old one... I just think that is way to many steps and will take longer to execute the code.

cUrl can be used to download a image into a $variable just like file_get_contents.

 

Like this :

 

<?php
$image = file_get_contents('http://www.example.com/image.gif');

$im = imagecreatefromstring($image);


....
/* resize / save the thumb */
....

imagedestroy($im);
?>

 

You can use cUrl to do the same jobs but with better error handling than file_get_contents.

 

Axeia have told that if gd functions can't read a URL like this :

<?php
$im = imagecreatefromjpeg('http://www.example.com/image.jpg');
...
?>

 

You can use others function to pull the image, like file_get_contents or cUrl.
