I had the same question a couple of days ago and I found a thread on the
mailing list, which I'm reposting here. Although this worked for me, I found
downsampling of the pdf with gs more convenient.
Here’s a shorter solution:
\startluacode
local function downsampler(oldname, newname, resolution)
if not resolution or resolution == "" then
resolution = 72
end
local cmd = string.format(
[[gm convert -resample %ix%i %s %s]],
resolution, resolution, oldname, newname)
-- print(cmd)
os.execute(cmd)
end
-- Set the PDF and default JPEG converters to the above function.
figures.converters.jpg.pdf = downsampler
figures.converters.jpg.default = downsampler
\stopluacode
You can set the resolution in \setupexternalfigure this way.
But the calculation doesn’t take scaling into account, I have this on my
todo list for too long…
And it should be possible to hook this into "conversion"…
