Where the text of a regular annotation would appear it instead has the string "cv5GW4xHvSmWMXVPefHzMPQ0". There is no apparent sign of an actual annotation image. Perhaps it is stored elsewhere on the device. |
As far as I can tell, that handwritten note is stored in a SQLite3 database (path: /.notebooks/uniqueString!!PDOC!!notebook/nbk for a personal doc, or uniqueString!!EBOK!!notebook/nbk for a purchased eBook). I am unable to actually open the database, though--sqlite3 is coming back with a "malformed schema" error on all of the nbk files I pulled from my Scribe, and running a recover on one just comes back with an empty database file.
Opening one in a text editor, though, does yield some information on how it's stored... For example (cleaned up a bit):
Code:
nmdl.type nmdl.free_form nmdl.stroke nmdl.stroke_group nmdl.color nmdl.brush_type nmdl.max_resolution_x nmdl.max_resolution_y nmdl.thickness nmdl.canvas_width nmdl.canvas_height nmdl.normalized_ppi nmdl.position_x nmdl.position_y nmdl.pressure nmdl.tilt_x nmdl.tilt_y nmdl.num_points nmdl.stroke_points nmdl.stroke_bounds nmdl.chunked nmdl.chunk_threshold nmdl.template_id nmdl.template_type nmdl.thickness_adjust_f
I'm assuming that each stroke gets stored, along with information on where it should be placed on a document. And based on those (assuming again) column names, there may have been a plan to include pressure/tilt information (or perhaps that will be added with a firmware update, assuming the hardware supports it).
That string you referenced is in one of the nbk files (path: /.notebooks/DBE32A7F4E1546E0BF5AEC5ADFD78916!!PDOC!!notebook/nbk).
