I used to annotate pdf files with xournal on my linux machine. Recently I purchased an android tablet and now use INKredible for the same purpose on the tablet.
Now I would like to have a program that converts between the two file formats, because sometimes the computer is more convenient and sometimes the tablet. Both programs store the annotations separately from the original pdf, which is just used as background. However, xournal creates just one additional .xoj file, whereas INKredible sets up one directory for each page of the original document, containing .html, .xml and .svg files.
Do you know a program that can convert at least in one of the directions?
Or can you recommend other software for that purpose where the same files can be used on both machines?
