Scan to djvu
(All software used here is available from the standard debian linux repositories.)
I scan a lot so scanning procedure must be simple and the resulting files must be small.
Most people use pdf
which is not the best format for scanning.
There is a djvu
-file format which was created primarily for scanning; normally djvu
scans are smaller than pdf
ones.
Here is an example for (perhaps most linux-friendly) HP-hardware.
Suppose that my "all-in-one" hp device has an ip address 192.168.52.17;
When I need to scan several sheets, I change to an empty directory and type
scanadf -d "hpaio:/net/Officejet_6700?ip=192.168.52.17" -v -o ${1}%02d.pnm --source ADF --resolution 300 --mode Gray make -f scan-Makefilewhere
"hpaio:/net/Officejet_6700?ip=192.168.52.17"
comes from the output of
hp-makeuri 192.168.52.17
make
command will convert all pnm-files in the current directory to all.djvu
Sometimes I email scanned documents; since I can not expect from people to know what
djvu
format is, I convert djvu
to pdf
:
ddjvu -format=pdf -quality=85 -verbose input.djvu output.pdf
Note: scan-Makefile is optimized for American "Letter" paper format; you might have to modify it for another (say, "A4") format.
