I love the physical design of the pen, and the IOS app is also fine. However, when a notebook is exported to PDF format, the pages are rasterized (bitmaps) rather than being the usual vector format expected with PDF. This means the files are both low quality, and large. For example, the display of a page within the Neo Notes IOS app is much better than the same page viewed in the exported PDF.
When the pen is mounted as a USB disk, I see a single .zip file that probably contains the notebook data.
If the format of this file was public, it would be possible (and maybe even easy) to write an exporter program
that would parse this, and generate a vector .pdf file.
Could I ask for the format of the data stored on the Pen? Is it possible to join the developer forum (I am a programmer)?
