[NTG-context] access image properties in Lua

What’s the current approved way to get image properties within a Lua function? very old: local pic = figures.getinfo(figures.current().status.fullname) used to work in 2019: local pic = img.scan{filename = figures.current().status.fullname} if I understand this right, "img" isn’t valid anymore: """ token call, execute: grph-imagelib.lua:37: attempt to index a nil value (global 'img') """ I’d like to know the pixel size and if possible also the scaled target size of an image; either the "current" one or by name.
