Create Instagram Filters With PHP
In this tutorial, I’ll demonstrate how to create vintage (just like Instagram does) photos with PHP and ImageMagick. Wait? What? Yes, you can do this very thing with PHP and ImageMagick, and that’s just scratching the surface!
IM (short for ImageMagick) has a nice wrapper, called Imagick – a native PHP extension to create and modify images using the ImageMagick API. The only downside is: you will likely have to install it from PECL, which can sometimes be a problem for shared hosting.
$image = new Imagick('photo.jpg');
$image->resizeImage(640, 480, imagick::FILTER_LANCZOS, 0.9);
