I have sent the trace file for a djvu file of version 4, unfortunately sometimes the trace file for a pdf file is created but empty ?
In any case, 1) what appears now on the e-reader side is unfortunately scrambled and unreadable, 2) it still does not rotate with the lcd side, sorry for not being able to bring some good news for a change.
Please let me know if you want more test, e.g. a working trace file for a pdf document, or tests for version 3,
In fact a big thanks to you for trying to improve the app, having pdf's and djvu's in landscape would be most useful for some documents as you can zoom in much more, much appreciated !
