Extract pen strokes from .note

[Bootstrap360]

Hello @jya-dev

Thank you for your contribution. I have spend a few hours poking around your source code and using the debugger to try and find where I can extract the list (x, y) values for each layer inside the .note file.

The closest I have gotten is the get_totalpath but I do not know how to dedecode this data.

I would also be interested in this, as it seems that the --pdf-type vector option is not using the actual pen strokes but rather tracing the png. So basically we are going from vector (original pen strokes) -> to raster (png conversion) -> to vector again, which seems unnecessary!
Amazing tool btw!

Hi,
As you suggest, I too believe that toolpath has the original pen strokes.
When I look inside the toolpath data in a binary editor there are areas that clearly look like coordinate data,
but I haven't yet found a way to parse this properly.

@jya-dev, I used your library as a basis of my own tools and have since unveiled some of the structure behind totalpath. See my last videos about a text to pen strokes tool below. None of that would have been possible without your work. https://youtube.com/playlist?list=PLO0R0numVXGXooMYGTEuUKE2GsAKEc127&si=5NdSg19mWRwP9fK1

@mmujynya, Great, thanks for letting me know. I'll check it out.

Happy to share what I know. It would be much more useful for the community to have the tools to extract and manipulate pen strokes in your project.

I have reverse engineered much of the strokes format with assistance from an agent. https://github.com/philips/supernote-typescript
