Image cropping script - need help

[Harley1979]

Hello,

 

I am using a nice little script I came across to crop images (here are the files: http://php.amnuts.com/index.php?do=view&id=12 - Demo: http://php.amnuts.com/demos/crop-canvas/interactive.php)

 

I now have it working ok, on the final stage it is writing the image out to the screen in the code here:

 

require('class.cropinterface.php');
$ci =& new CropInterface(true);

if (isset($_GET['file'])) {
    $ci->loadImage($_GET['file']);
$ci->cropToDimensions($_GET['sx'], $_GET['sy'], $_GET['ex'], $_GET['ey']);
$ci->showImage('png', 100);

exit;
}

 

My question is how do I make this image a jpg file and save to a directory? I've only done simple file upload scripts before now and don't have much of an idea how this is gonna work.

 

Any help is much appreciated.

 

Thanks

 

Harley

well, you'll need the function imagejpeg regardless, but I know nothing about that script (I hate premade scripts, such a hassle to mod), so I wouldn't know how to integrate it into the code.

Yeah I know what you mean about using premade scripts, not something I'm in the habbit of doing but i really need this functionality on a site I'm doing really badly.

 

I'm not sure where my fall down is here, it may be that I don't know enough about creating images with php or just that I am hopeless with objects, properties and methods as that is what this script heavily uses.

 

If anyone else has any ideas please let me know.

 

Thanks
