PHP uses Imagick to crop/generate thumbnails/Add watermarks to automatically detect and process gif_php instances

The Imagick part of the image library developed for the bone system, which supports GIF, perfectly supports trimming, generating thumbnails, and adding watermarks.

Supports generating thumbnail images by orientation, such as:

The upper left corner of the priority $image->resize_to (the "north_west");//Right Priority $image->resize_to (+, +, ' East ');

More parameters See source code
