Re: [libreoffice-users] Non-PDF Portable Document Formats (Exporting from LO)
Hi :) I'm not clear why not jsut have everyone install Libreoffice alongside whatever other programs they have and then encrypt the ODF files (odt for text, ods for spreadsheets etc) Regards from Tom :) On 2 April 2014 18:48, Hal Vaughan wrote: > I'm working on an e-reader for special purposes.

Google is your friend ;) Yes, I’ve spent many hours on this on Google. I was hoping that there might be something I couldn’t find or didn’t know about that might help. And, actually, the DRM is encryption that I’d be handling on my own - basically wrapping a file input stream with an encryption stream.

RE: [libreoffice-users] Non-PDF Portable Document Formats (Exporting from LO)
Top posting answer to Hal... See either of two ways to proceed, since LibreOffice already bases it PDF page rendering on Poppler and bundles it, you might as well work against that and write a LibreOffice extension. Alternative might be the java source code from Writer2LaTex project (http://writer2latex.sourceforge.net/ ) for the Writer2xhtml that will handle ODF document conversion directly to EPUB. Or simply use the extension as is with LibreOffice.

[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!
