The short answer:
Maybe, but the method I found requires you to compile a program from source, and I had no luck with it.
The long answer:
Possibly. I've never heard of or used DjVu files before, but here's what I found:
http://planetdjvu.opendoc.it/viewtopic.php?t=543
Apparently, "JRAPublish 3.0 [is] the only product on the market that will convert searchable-image DjVu to searchable-image PDF". Doesn't look too "free" though.
However, the last post says:
"The latest version of the djview4 viewer
has a convenient exporter that can produce TIFF or PDF.
Select File->Export as, then choose PDF.
Download from
http://djvu.sourceforge.net/djview4.html"
The djviewer in my repos (Kubuntu Feisty) didn't have such an option. I downloaded the source from the sourceforge site, but the configure script kept choking on a syntax error at line 7006:
Code:
user@machine:~/Desktop/djview4-4.2$ ./configure
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
.....
checking for IceConnectionNumber in -lICE... yes
./configure: line 7006: syntax error near unexpected token `;;'
./configure: line 7006: ` ;;'
Not sure what the deal is here, but it refuses to work, so I can't help any further.
You might try printing from a DjVu viewer (like djviewer) to a PDF printer. I am able to print to pdf from some programs after installing the cups-pdf package.
