The XPS document format is used by Windows to save a document when the document writer is used. The document reader in Ubuntu can open these just fine, but I wanted to be able to convert one to a PDF document. This is how I did it with the command line.
Install the libgxps-utils package with apt.
jason@jason-desktop:~$ sudo apt install libgxps-utils [sudo] password for jason: Reading package lists... Done Building dependency tree Reading state information... Done The following package was automatically installed and is no longer required: libllvm9 Use 'sudo apt autoremove' to remove it.

Then run the xps2pdf command to convert the XPS format to a PDF.

This is a very simple way to convert these files to PDF format using the Linux command line. This is very simple to do indeed. The resolution and DPI can be changed with command-line arguments, but this did not seem to make any difference when I used them. Just use the default command to convert as is. This works just fine.
To convert a PDF file to the DjVu file format, use this simple utility.
jason@jason-desktop:~/Documents$ pdf2djvu ivermectin.oxps.pdf -o ivermectin.djvu ivermectin.oxps.pdf: - page #1 -> #1 - page #2 -> #2 - page #3 -> #3 - page #4 -> #4 - page #5 -> #5 - Warning: metadata[CreationDate] is not a valid date 0.144 bits/pixel; 3.890:1, 74.29% saved, 2956110 bytes in, 759977 bytes out |
The pdf2djvu utility is a perfect way to do this and provides a good quality conversion. Specifying the DPI value as 300 helps with the quality of the output.
jason@jason-desktop:~/Documents$ pdf2djvu ivermectin.oxps.pdf -o ivermectin.djvu --dpi=300 ivermectin.oxps.pdf: - page #1 -> #1 - page #2 -> #2 - page #3 -> #3 - page #4 -> #4 - page #5 -> #5 - Warning: metadata[CreationDate] is not a valid date 0.144 bits/pixel; 3.890:1, 74.29% saved, 2956110 bytes in, 759977 bytes out |
