Crop image using php

Question

I want to crop an image. Is it possible to do like this. And if yes, how would the crop() function look like?

$imgURL is always a .jpg image.

$image = file_get_contents($imgURL);
$maxWidth = 100;
$height = 68;

$image = crop($image, $maxWidth, $height);

file_put_contents("media/imgname.jpg", $image);

function crop($image, $maxWidth, $height){
    ...how do I crop the image?
}

Answer 1

Take a look at the gd library that's usually part of most PHP installs.

Typically, you'd:

1. import the image using one of the imagecreatefromTYPE functions
2. use imagecreate($width,$height) to make a blank buffer image
3. use imagecopy() to transfer the portion you want to the buffer
4. use one of the imageTYPE functions to write the buffer out to a file.

If you have the GD library installed, taked a look at the functions available to you. If you want more explanation and an example, take a look at this blog.

Also, there's plenty of SO posts to help you along.

Another option you may be able to use is Image Magick if it GD is not installed on your server.
