Hello Henning,
This is really interesting, but my original question was about the file path resolver, i.e. how to
get "t:/sources/cow.pdf" from just "cow"?
I guess there was a similar question here:
https://mailman.ntg.nl/pipermail/ntg-context/2017/088324.html
Reading till the end, I deduce one has to collect snippets which appear in the code to build its
own "file locator" as no function like "MyExternalFigureLocator()" exists in
ConTeXt/Lua API.
Some highlights:
----
Personally I use the lua variable named : figures.path
It’s a lua table which contains directories names you provide in directory= in
\setupexternalfigures:
for _, path in ipairs(figures.paths) do
local figure_file = path .. '/' .. file
local doc = lpdf.epdf.load(figure_file) -- assume pdf (just an example)
if doc then
….
end
done
----
Unfortunately, this code supposes the figure name was passed WITH extension, as
no lookup in table-of-valid-extensions is performed (maybe no such table nor
iterator exists).
There should be also:
----
local n =
"x:/Users/MMi/Akce/I-6_Krusovice.DSP-ZDS/Admin/Jednani/2017-07-07-SU-Rakovnik/ZJ.pdf"
local d = figures.getinfo(n)
inspect(d)
----
And a snippet from another mailing thread:
---- (Hans' answer)
\getfiguredimensions[test.pdf]
\dorecurse {\noffigurepages} {
\getfiguredimensions[test.pdf][page=#1]
\figurenaturalwidth
,\figurenaturalheight,\figureorientation,\figurerotation\par
}
in lua you can either use the img library (see luatex manual) or context
helpers
local data = figures.push("foo.pdf")
figures.identify()
figures.check()
figures.pop()
inspect(data)
i'll add:
function figures.getinfo(name,page)
if type(name) == "string" then
name = { name = name, page = page }
end
if name.name then
local data = figures.push(name)
figures.identify()
figures.check()
figures.pop()
return data
end
end
so that one can do
local n = "ms.pdf"
local d = figures.getinfo(n)
if d then
for i=1,d.used.pages do
local p = figures.getinfo(n,i)
if p then
local u = p.used
print(u.width,u.height,u.orientation)
end
end
end
----
Hope this helps.
Best regards,
Lukas
