Replicate Instragram-style filters in PHP. Translates photoshop functions to PHP.

The tmp directory must be writable.

Fork and pull request any useful changes you make.

\Instafilter\Image::load('kittens.png')
	->resize(200, 200)
	->apply_filter(new Instafilter\Filter\Earlybird())
	->save('new.jpg');

n.b. applying the filter is quite slow; You'll get a significant performance gain by resizing before applying the filter.

If you don't use an autoloader, you'll need to load in the classes:

require_once('classes/Image.php');
require_once('classes/Filter.php');
require_once('classes/Filter/Earlybird.php');
require_once('classes/Filter/Inkwell.php');

• Add more filters
• (Somehow) Improve performance
• Improve interface
• Implement more photoshop functions in imagemagick
  • Implement 'curves' properly by using polynomial regression to get the coefficients needed for imagick's FX function
• Abstract and decouple from Image class
• Make composer/packagist compatible
