Hi, I use the lua function img.scan{filename}, but in lmtx I get "attempt to index a nil value (global 'img')", so I guess this got renamed or moved? HR

Finally coming back to this. Since I don’t know what the function is supposed to return, I thought I’ll check: local image = figures.getinfo(imgname,1) print("TEST", image, #image) for k, v in ipairs(image) do print("TEST", oldname, k, v) end but that gives only: TEST table: 0x7fbd4e4e1320 0 i.e. the table is empty. Or did I misunderstand something? My Lua skills are still severely lacking... Hraban
