so far, i've found imagemagick. scan everything to PNG and then i run: convert -verbose -threshold 50% -quality 100 -type bilevel -adjoin *.png out.pdf it worked well, about 45 MB of grayscale images to 2.5 MB PDF file. but, it's dog slow and takes a ton of memory, for just 30 images it took about 30 minutes and all kinds of swap memory.. brought my system to it's knees (it's a six year old laptop though). it would be nice if there was a way to force the backend to offer lineart, maybe by making some changes in the source? i'd like to see if it's possible. -----BEGIN PGP SIGNATURE----- iEYEAREIAAYFAkv4jb0ACgkQXhfCJNu98qCvAQCgo8EKkMjaN2DGu+UtGOOWxthe k8sAoKLPSHe6sBA+rSQ4bunG68YjTNTA =OeqF -----END PGP SIGNATURE-----
