I can't figure out how to determine the number of pages of a PDF
file within lua. From the TeX side it works with
\getfiguredimensions
Can somebody give me a nudge in the right direction? Example:
\starttext
% Works
%\getfiguredimensions [somefile.pdf]
\startluacode
-- Does not work
context.getfiguredimensions({"somefile.pdf"})
local numpages = figures.get("used", "pages", 0)
context(numpages)
\stopluacode
\stoptext
something
local fig = figures.push { name = "somefile.pdf" }
figures.identify()
figures.check()
local nofpages = fig.used.pages
figures.pop()
