Scanbook is a Python script I wrote to take page image scans and turn them into a nice black-and-white PDF for reading on my phone. I used to use Scanner Pro for this, but I’d rather do the processing on my laptop, and Scanbook happens to produce smaller PDFs. I’ve used it to scan a dozen or so of my journals; it works well enough for me.
This is, by the way, my first time publishing anything on PyPI. (Which means people can install Scanbook with a simple pip install scanbook.)
Just posted some note paper PDFs which I made in PlotDevice. There’s lined paper — 30 lines/page up to 130 lines/page (for those who write really, really small) — and graph paper — 10×10 up to 140×140.
