Flexibility. With G&#x27;Mic it&#x27;s easy to implement a new feature or a plugin. With ImageMagick, I wouldn&#x27;t even know where to start. Esoteric command line input is not my definition of a user interface designed for artists.<p>Plus it comes bundled in with Krita and Gimp.<p>Just as a sidenote, if you like playing around with G&#x27;Mic, you might absolutely love Python+OpenCV+Numpy combination. It&#x27;s crazy powerful for tiny amounts of code required.
