ValueError: not enough image data

[cwhittl]

Running the code below, trying to make an automated process to use DropBox and also be able to read the notes. `find ../Supernote type f -name ".note" -print0 | while read -d $'\0' file do newFile="${file%.}.pdf"

TODO compare last updated

supernote-tool convert -a -t pdf -a "$file" "$newFile"

done ` It creates one PDF successfully but then I get this error on the others.

Traceback (most recent call last):

I am running this on a M1 Mac running Ventura and I have a brand new Supernote A6X running the latest version.

Thanks!

Hi, I haven't been able to reproduce that phenomenon. If you don't mind, could you share the file causing the error?

If you notice the difference between a file that causes the error and a file that does not, I would be happy if you could let me know. It is my guess that using a custom background may cause that error.

The only difference I can see is that the one that converted uses a builtin SuperNote template and one of the ones that didn't uses a custom imported template (loaded through MyStyle folder) I've attached one that converted and one that didn't. Archive.zip

Just for further experiments I tried to do png as well and it failed with the same error.
