LXVI. Image magick Functions

Einführung

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

Anforderungen

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

Installation

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:

  • Either:

    • Run the pear installer for PECL/imagick: pecl install imagick

    • Copy imagick.so from the directory indicated by the build process to the location specified in your php.ini file under extension_dir.

    • Add extension=imagick.so to your php.ini

    Or:

    • Set the path to your php.ini via:

      pecl config-set php_ini /path/to/php.ini

    • Run the pear installer for PECL/imagick: pecl install imagick

  • Restart your web server to reload your php.ini settings.

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

Compiling PECL/imagick without using the PEAR command: Rather than using pecl install imagick to automatically download and install PECL/imagick, you may download the tarball from PECL. From the root of the unpacked tarball, run: phpize && ./configure --enable-imagick && make to generate imagick.so. Once built, continue the installation from step 4 above.
