Subject: access image properties in Lua
Date: Tue, 11 Jul 2023 14:22:30 +0200 [thread overview]
Message-ID: <280ddf65-40a2-3b4c-add5-5de39e15d8e7@fiee.net> (raw)
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.
Hraban
