I want to know which JPEG encoder is used in ImageMagick.
- Is the default JPEG encoder libjpeg?
- Can we use Guetzli encoder (JPEG encoder made by Google, https://github.com/google/guetzli) and mozjpeg (JPEG encoder made by Mozilla, https://github.com/mozilla/mozjpeg/) in ImageMagick?

The default is libjpg. I do not know if others can be used. Perhaps if you set up a command in your delegates.xml file. One of the other uses or developers can tell you more.
