[ax3l]

The file format was updated to v3. Investigate the changes.

Hello,

Apparently, there are answers here.

I've just thrown a look quickly but will try to grasp it better by playing with the device.

I little bit more info.

The extension of encoded files is now .rm and we have one .rm file per page, meaning the top level object in the binary is now the Layer. Here is the .zip file structure for a 2 pages note.

And taken from the link I attached in my previous comment, here is the binary format.

#  header: 'reMarkable .lines file, version=3          '
#  4 bytes integer: number of layers
#  for each layer: 
#      4 bytes integer: number of strokes
#      for each stroke:
#          4 bytes integer: pen
#          4 bytes integer: colour
#          4 bytes: unknown
#          4 bytes floating point: width
#          4 bytes integer: number of segments
#          for each segment:
#              6 floating point numbers: x, y, speed, direction, width, pressure

With strokes being what you call lines and segments what you call points.

Thanks!

I updated the low-level, per-page read and write handling in #16.

Functionality restored as of #18 :)
