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?

Just the high level command:
figures.getinfo(name,page)

Coming back to this, I can’t find "figures.getinfo" in the sources. Is there any documentation?

Just the high level command:
figures.getinfo(name,page)
local t = figures.getinfo("name.pdf",10) -- optional page number

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...

it's a hash not an array so .... pairs

Oops. Ok, that means the information I’m looking for is in image.status.private. Who would have thought.
Now grph-downsample.lua works with LMTX.
