简介

Image magick extension lets you create and manipulate images. Its function is similar to Image extension but provides more powerful and faster functions.

需求

To use this extension, either "ImageMagick" or "GraphicsMagick" library is required.

安装

Windows binaries may be found at » http://snaps.php.net/. To install, download php_imagick.dll to the folder specified by your php.ini file's extension_dir directive. Enable it by adding extension=php_imagick.dll to your php.ini and restarting your web server.

extension_dir=c:/php5/exts/
extension=php_imagick.dll

Linux, BSD, and other *nix variants can be compiled using the following steps:

Development Versions: There are currently no stable versions of PECL/imagick, to force installation of the beta version of PECL/imagick execute: pecl install imagick-beta
