Does ImageMagick have OpenCL GPU acceleration? If it’s not in the official version, surely there is a development branch with the feature out. Looks like there was a patch made and merged into the master version of the source code. The OpenCL GPU acceleration is only implemented on some operations, such as resize. That is one of the most important and essentials operations to accelerate for me, so that works out quite nicely for me.
Note that you have to verify if your particular build of ImageMagick includes the OpenCL acceleration. If not, you’ll need to rebuild your own ImageMagick with the feature enabled.
