To embed text into a Djvu file, you must create a djvused
script detailing the page and bitmap location of one of: character, word, line, paragraph, or region.
For good measure, you should first list the contents of your Djvu bundle:
$ djvused -e 'select; ls' test.djvu
1 P 177062 p0001.djvu
2 P 199144 p0002.djvu
3 P 12323 p0003.djvu
4 P 57059 p0004.djvu
5 P 96725 p0005.djvu
6 P 53868 p0006.djvu
Then define the location of text in a file called, for instance, content.dsed
. Assume that my page is 1000 px by 1000 px:
select; remove-ant; remove-txt
select "p0004.djvu" # page 4
set-txt
(page 0 0 1000 1000
(word 100 600 450 800 "Hello" )
(word 100 600 450 800 "world" ))
.
select "p0005.djvu"
set-txt
(page 0 0 1000 1000
(line 100 400 900 600 "Hacker Puppy Radio"))
Apply this script to your Djvu file with dvjused
:
djvused -f ./content.dsed -s test.djvu
You can convert PDF files to Djvu with the djvudigital
command. Due to license incompatibility, it does require you to compile a Ghostscript plugin, but it's an easy build. Get the gsdjvu code, and then follow its README instructions.
Once you've built the Ghostscript driver, you can convert PDF to Djvu:
djvudigital --words foo.pdf foo.djvu
