Inkie is a little tool to determine a comparable number of ink used on scanned pdf forms with handwriting on them, because thats how Members of the European parliament submitted their declarations of interest. Inkie was written during the Europarl Hackathon for the European Elections 2014.
Install required node modules with
npm install
Put the PDF documents to data/pdf and convert them to deskewed PNG images with
./convert.sh
After that run
node inkie.js
to calculate the inkness factors. These will be written to data/inkness.json.
To further sort documents and pages by inkness, you may run
node compare.js
which writes its findings to data/doc-inkness.json and data/page-inkness.json
