Laravel Intervention - get ImageMagick instance

I´m using laravels Intervention library to manipulate an image (width Imagemagick as driver). In this process I also have to do a perspective transform on the image and as Intervention doesn´t provide such an method I want to use Imagemagicks distortImage. So, now my question: How do i get the Imagemagick instance of my current image out of Intervention (if possible). Right now I´m encoding the image as png via Intervention and read the image blob in an new ImageMagick instance - is there an better/easier way?
