True, but I don't interpret that to be OP's objection. Gscan2pdf does
solve the problem, at least paritally / mostly.
I tried it on my system. While 'convert *.jpg result.tif' succeeds in
creating a multipage tiff, but 'convert *.jpg result.pdf' fails with
But I am able to use gscan2pdf to import large number of jpegs write
pdf. I say the problem is only "mostly" solved because it does not
appear that you can feed a group of images from a command line and
automatically spit out a pdf. (Not really surprising for a GUI tool)
If a command line soltution is needed, maybe make the intermediate tiff
and then use tiff2pdf. Try the -n switch if you get weird colors, the
-j switch to recompress and -q <qual> to set jpeg compression if you
don't like the default. Oh, and the default output is stdout, so you
need an explicit -o <filename>.
As you can tell, I fiddled a little. I could not figure out how to get
tiff2pdf to take input from stdin anyone who's had success can chime in.
