Stylus writing on boox note

sorry, do you know, can notes be backed up without a cloud connection? In previous versions of the software they had the possibility of a local backup. Now I haven’t seen this possibility.

Yes, you can. Instructions from the github page:

“Turn on the WiFi on your device (because of the bug in the reader that doesn’t let you to create a backup of notes without WiFi enabled), go to the note app, select the three-line-menu from the top, Backup and Recover, select the floppy disc icon, choose a filename, click ok. Wait until the notes are exported. Connect the device to your computer, and copy over the zip file generated. It is in folder note/backup/local/.zip. Copy that over to the computer, and run this tool on it.”

After I created an Onyx account, I was able to make a local backup, but running the program onyx_render.py I get an error (I took a screenshot). The backup is called “fisiere.zip” and is placed in C: \ users \ user \ Desktop.


Can you guide me a little more?
Thanks!

Dear rafail,

It needs python3, won’t work with python2. You will also need pycairo which is tricky under Windows. The easiest way to get it is from here I guess: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pycairo.

Once you installed that manually, (pip install whatever.whl), you could install the rest of the requirements with pip install -r requirements.txt.

You could also try the exe file in the releases which should not need any dependencies (https://github.com/xdever/OnyxNoteRenderer/releases/download/v0.2/onyx_render.exe).

Sorry guys, I know that a lot of you uses Windows, but I have no clue how to make python run on it. Nor I have access to any Windows machines. My only experience with it is what I gained while tried to build that exe file above.

There is a relatively easy way to run this code under Windows10: use Linux Subsystem for Linux (https://docs.microsoft.com/en-us/windows/wsl/install-win10), install an ubuntu system. In that one can easily install all the prereq of this code:
$ sudo apt install python3 python3-numpy python3-cairo python3-tqdm
after that you can run by:
python3 onyx_render.py your_backup.zip your_out_dir

Gubi debugged the code on Windows. Now the exe file should work along with the older note files (without WSL).

Quick link: https://github.com/xdever/OnyxNoteRenderer/releases/download/v0.2/onyx_render.exe

Instaled python 3.8, updated pip to 19.x.x, instaled python accesories pycairo, numpy, tqdm, and…
Succeeded!
The notes are looking excellent!
Great job, xdever!
Thanks a lot!

so i have a brand new note 2, firmware date 6th Nov '19, it has the auto refresh feature, but my notes are jagged and zoomed in on a PDF looks pretty bad. Is it just going to stay that way or will Onyx fix this? For me it’s pretty much “send back the device” if this doesn’t get fixed. it’s flippin pricey to look this bad.

I just added a new tool for smoothing PDF annotations. For now only works with non pressure-sensitive annotations and there is no exe yet, but coming soon(ish).

For more details, check the instructions at the Github page.

Just updated the fix_pdf tool. Now it can handle both pressure-sensitive and insensitive annotations. I also built an exe file that should work on windows without any dependencies.

Not sure if it’s the same problem, but I found that NeoReader (in 2.1.2) exports annotations worse than displays. See screenshot (upper is png screenshot from Note Pro, bottom - from Acrobat Reader for Windows):

Please fix it.

Try using non pressure sensitive pen. Pressure sensitive is causing problems, especially if you zoom-in and write - it can be unreadable when exported. Boox support said they are aware of that and they are working on it.

I tried the program posted by xdever for smoothing PDF annotations and it work greate. I attach a page with annotations in a pdf file before and after processing with the package launched by xdever, which opens up a lot of possibilities in processing notes from Onyx.
An issue that is mostly solved is the difficulty to migrate between the Note application and the NeoReader application to create notes while reading on a page larger than half a page, available in sidenote mode - quite difficult for the Onyx Note device.
So: I created a pdf document with white pages, or with liniature, which I opened in the NeoReader application in which I can create scribbles like in the Notes application, at just a click away …!!! And the pdf file with these notes can be smoothed, like simple adnotations…

Well, the new 2.2.1 firmware is as bad as the 2.1.2 was. No change at all.

The line smoothing feature is something that they definitely must include in the next firmware update. I just got my Note2 and the first thing I google was why it does not do line smoothing. I tried the app from xdever and that is how, I think, all of us expected to be the writing experience in term of rendering.
Excelent work xdever, now to wait until boox include this in the next release.

Unfortunately there is a problem … The pdf file with the smoothed annotations (by applying of your program from github) opened in NeoReader3 shows the initial rude annotations, even if the old pdf file on which I had made the annotations was deleted …

Xdever, it would be difficult to arrange a .svg file in the .bd format that the files from an Onyx back-up have?
That would open up a myriad of opportunities. For example, we could continue a sketch from Adobe Illustrator in the Notes application, also we will be able to reintroduce an old note saved as a pdf again in the Note application and reprocess it, and, especially we could apply the wonderful AI module of Onyx for other handwritten documents (photos after pages from older notebooks, processed in Illustrator, could be made searchable) etc …

It should not be difficult to do it, it is just lot of work. Basically you can take the file format specification from my github page and just add a new entry - a new sqlite table for the file, and the new entry in the list of files.

For loading the modified annotations: I have never tried it, but in theory it should work - I use the same smoothed data to render it on the device.

If you can run the python version (not the exe), could you retry it after editing fix_pdf.py, and changing n_subsample = 2 to n_subsample = 1? I guess that should fix the loading issue on the device. (I don’t have Windows, but I can ask my friend on the weekend to generate me another exe with this modification).

Modifying n_subsample doesn’t solve the problem, but printing the smoothed pdf into a file using Adobe Acrobat printer.

Hi there, may I know if there’s any update on the upcoming firmware that improve pen smoothening?
