How to convert from pdf to djvu (2 methods)

[starplex]

One of the main reasons to convert a pdf file into djvu is to save space. I've seen 577MB PDF file become 95MB DJVU after conversion. But a lot depends on the converter chosen and of course, the settings.

Method 1: The easy pdf2djvu


Installed by

sudo apt-get install pdf2djvu

After it's done just open a terminal and type

pdf2djvu -o output_file input_file

input_file being the pdf you want to convert.

Method 2: The harder way djvudigital

Step 1:

sudo apt-get install djvulibre-bin djvulibre-desktop djvulibre-plugin

Step 2: download the latest GSDJVU from here http://sourceforge.net/projects/djvu/files/GSDjVu/

Step 3: Extract it somewhere and inside create a new directory named BUILD

Step 4: download latest

• Ghostscript http://sourceforge.net/projects/ghos...r.bz2/download
• Ghostscript fonts http://code.google.com/p/ghostscript...ar.gz&can=2&q=
• JPEG src http://www.ijg.org/files/jpegsrc.v8d.tar.gz
• LIBPNG ftp://ftp.simplesystems.org/pub/libp...g-1.5.9.tar.gz
• Zlib http://zlib.net/zlib-1.2.6.tar.gz

Put these files in the BUILD directory you created in step 3. Do not extract them

Step 5: download http://sourceforge.net/tracker/index...53&atid=406585 and put it in the GSDJVU directory.

Step 6:

sudo apt-get install patch

. In terminal go to the GSDJVU dir and type

patch -p1 < 0001-Upstream-removed-gserror.h-in-gs905-commit-8f2ecf4.patch

Step 7: RUN the shell script

build-gsdjvu

. USE FULL PATHNAME. eg /home/sam/gsdjvu/build-gsjvu

Step 8: Wait

Step 9:

sudo cp -r BUILD/INST/gsdjvu  /usr/local/lib

sudo cd /usr/local/bin

sudo ln -s ../lib/gsdjvu/gsdjvu gsdjvu

You are now ready to run djvudigital. Just type

djvudigital input_file output_file

and all should be well.
