As the list of nodes offered by that node doesn't seen to include image I would contact the author direct via their github project and ask there.

It should be possible to do pixel by pixel. The matrix is of course kind of not easy to figure out.

Thank you i think i managed to do it using imageJ software and convert to X,Y coordinate .
Hope there's other easier ways.
