Is it possible to use GraphicsMagick instead of ImageMagick to generate Thumbnails in the MODX media browser

We have performance issues on our server when thumbnails are created in the media browser with ImageMagick. Our provider told us to use GraphicsMagick instead.

Unfortunately we could not find a way to force MODX to use it.

Is it possible to use GraphicsMagick to generate Thumbnails in the MODX media browser?

MODX uses the PHP library phpThumb to generate the thumbnails:

This library supports GD and ImageMagick. I don’t think GraphicsMagick is supported.
