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...
