This can be done once and is much better than getting ConTeXt to

Do you really think that we let context convert a big file each run
in a critical workflow? Context will only resample when an image
file changed (which happens when you have to process from
repositories updated by authors).
I guess that's a question for me ?
More for Alan.
of course I don't plan to run context on the big files every time -- as I know
that that's still way too slow;)
but it would be nice if I don't need magic external tools to guess
the correct physical print size, calculate the actual number of pixels for e.g.
300 dpi, etc.
150 pixels is probably enough for color print ... if you have raw files
you can also consider png
anyway, i need to think a bit about it but we do have all the info
available, like
- needed width/height
- original width/height
and from that we can calculate some conversion parameters
if it would help you i can provide a tracker that will save info like
this (per image):
["used"]={
["colordepth"]=0,
["depth"]=0,
["format"]="pdf",
["fullname"]="t:/sources/cow.pdf",
["height"]=13156352,
["name"]=false,
["pages"]=1,
["path"]=false,
["suffix"]=false,
["width"]=18089984,
["xresolution"]=0,
["xsize"]=18089984,
["yresolution"]=0,
["ysize"]=13156352,
},
finally I like the idea to be able to create the final PDF in a "single"
context run
from *original* source (== original JPGs) without lots of additional tools and
steps/scripts
(or if I want to start over "form scratch" from input files).
that is what we also prefer: only luatex/mkiv + gm / gs
