A convenient way to convert files from DjVu to PDF format while preserving the text layer.
The solution utilizes djvu2pdf script, which, in turn, depends on other libraries like pdfbeads, djvulibre-bin, etc.
- All dependencies are packed into docker image (amd64).
- Some libraries are installed from source in order to utilize specific features: JBIG2 and JPEG 2000 (JP2) compression support.
- JP2 configuration in pdfbeads is modified.
docker run --rm -u $(id -u):$(id -g) -v $(pwd):/opt/work ilyabystrov/djvu2pdf filename.djvu filename.pdf- --rm option - removing container after execution
-
-u
$(id -u):$ (id -g) - run process with the same UID and GID - -v $(pwd):/opt/work - (required) bind mounting of the current directory to the working directory in the container
Put the following line into ~/.bashrc or a similar configuration file:
alias djvu2pdf='docker run --rm -u $(id -u):$(id -g) -v $(pwd):/opt/work ilyabystrov/djvu2pdf'It will allow using the short command
djvu2pdf filename.djvu filename.pdf
