Error when trying to convert .rm file to .pdf or .svg

[Joogle]

Hi, thanks for your work on this! When I try to run either: poetry run rmc -t svg -o file.svg /path/to/file.rm or poetry run rmc /path/to/file.rm -o file.pdf (I installed rmc via poetry) I receive the following error:

Sub-block starting at 8375, length 121, only read 1
Block starting at 8353, length 143, only read 23
Traceback (most recent call last):

    raise ve_exc

During handling of the above exception, another exception occurred:

Does exporting to PDF using official ReMarkable software work? IE when you send the relevant notebook as an e-mail attachment to yourself?

[ricklupton]

@Joogle can you share the file that causes the error, or ideally a minimal small example that also causes the problem, if it is not private?

[Joogle]

@Azeirah, @ricklupton I'll try to test the official software and share the file later, when I have a bit more time. I also realized, that there might have been a misunderstanding on my part concerning the functionality of rmc. I tried to use it on .rm files of an annotated PDF, not on .rm files of a notebook. And I'm not sure whether that's inside the scope of rmc?

[ricklupton]

It doesn't currently overlay the annotations on top of the original PDF, but the drawing should be stored and converted from the .rm file just the same as if it was a notebook.

Retried it when trying to build an example to replicate, now seems to work with Remarkable Software Version 3.3.2.1666
