It does not seem to be correctly installed, at least on the latest M2 version I have used to spin up a server here.
In php.ini, I have uncommented that extension:
; Local Variables:
; tab-width: 4
Restarted apache and other services
I added a simple test page which is just dumping phpinfo() and Image Magick is not listed.
On the command line, trying to look at php settings using
php -i|grep magick
PHP Warning: PHP Startup: Unable to load dynamic library '/opt/bitnami/php/lib/php/extensions/imagick.so' - libMagickWand-6.Q16.so.4: cannot open shared object file: No such file or directory in Unknown on line 0
