[libreoffice-users] Non-PDF Portable Document Formats (Exporting from LO)

I’m working on an e-reader for special purposes.  While I don’t want to go into a discussion of the 
point of this program and why I’m doing another, a brief summary may help.  As a writer, I don’t 
like sending my work over email or other insecure methods of internet transfer.  This e-reader 
would let me (and my writer friends) share our work easily with our friends while keeping it 
encrypted during transfer and even on the reader’s computer.  The file is read in and decrypted 
when displayed for reading.  This would also let me make early drafts expire so they can be ditched 
when they’re obsolete.

I still haven’t decided what language to use for this.  Initially it’ll work on OSX, Windows, and 
Linux.  I’d like to expand it to Android and iOS.  There’s a good chance it’d be in C++ or Java, 
but it would be great if I could do it in Python.  (I know of Kivy and other efforts that would 
make it easy for me to transport Python to at least Android.)

The problem is I need some kind of portable document format.  I know that implies, immediately, 
PDF.  However, there seems to be only one library that handles PDF display, and that’s Poppler.  
I’m not an expert programmer (at least not in C++), and when I’ve asked for help from the Poppler 
people, they’ve been abrupt and less than helpful.

I’d like to be able to write in LO, then save or export my file, and have it in a format I can 
easily display on the different operating systems.

I tried saving some files in HTML.  The plain text ones were no problem at all.  Margins and 
formatting was preserved just as I needed it.  But then I tried one that was part of a pitch, so it 
had a page of text, then a page of pictures, basically two columns of pictures with captions below 
each picture.  I loaded that in a browser and the formatting was okay on the first page, but was 
totally messed up on the 2nd page with the pictures.

As best I can tell, at this point, there is not a portable library out there that I can use from 
within a program to easily display ODT files, but that would be a great solution.

So what format can I use when exporting from LibreOffice, other than PDF, that can be easily 
displayed by any libraries in either Java, C++, or Python?


Thanks!
