Questions tagged [imagick]

Imagick is a native php extension to create and modify images using the ImageMagick library. Please upload example images to imgur.com (or other site) if your question is asking why Imagick is not producing the images you are expecting, so that people can reproduce your problem.

Imagick is a PHP extension to create and modify images using the ImageMagick library. There is also a version of Imagick available for HHVM. Although the two extensions are mostly compatible in their API, and they both call the ImageMagick library, the two extensions are completely separate code-bases.

ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.

The documentation for PHP Imagick is in the PHP Manual. A large number of examples for Imagick with code and the expected output are at PHPImagick.com
