Cropping image in PHP

Question

I\'d like crop an image in PHP and save the file. I know your supposed to use the GD library but i\'m not sure how. Any ideas?

Thanks

To crop an image using GD you need to use a combination of GD methods, and if you look at "Example #1" on PHP's documentation of the imagecopyresampled method, it shows you how to crop and output an image, you would just need to add some code to that to capture and write the output to a file...

There are also other options, including Image Magick which, if installed on your server, can be accessed directly using PHP's exec method (or similar) or you can install the PHP Imagick extension, which yields higher quality images and, in my opinion, is a little more intuitive and flexible to work with.

Finally, I've used the open source PHPThumb class library, which has a pretty simple interface and can work with multiple options depending on what's on your server, including ImageMagick and GD.
