How to save the images processed with Imagick as file

Scenario: You created with Imagick a cool thumbnail, and now you want to send it to a buffer other than the browser window. We already saw that it’s possible to process images on-the-fly, for example you have a 1024*768 wide image and you want to show its thumbnail version without having a thumbnail for the respective image. So what we do now is the exact opposite: we load the image in Imagick, process it, then save as a file. Probably this is the most encountered situation when processing images.

Let’s see the code, then I explain it step by step, as usual:

$im = new Imagick('/path/to/your/image.jpg');
$im->thumbnailImage( 100, null );
$fp =fopen('/path/to/the_new/thumbnail.jpg', 'w');
@fwrite($fp, $im);
@fclose($fp);

Now the explanation:

1. st line: we loaded the image in Imagick, it’s now ready to be processed
2. nd line: this time we create a thumbnail, store it in memory/cache: the X axis to be 100 pixels and preserve aspect ratio by setting the second parameter to ‘null’
3. rd line: create a new file, you specify the path. The file shouldn’t exist, but all the directories Yes! W means we open the file for write
4. th line: we write the Imagick object’s ($im) content in the open file
5. th line: and finally, we close the file

That was all. We saved again the world.
