supernote-tool

supernote-tool is an unofficial python tool for Ratta Supernote. It allows converting a Supernote's *.note file into PNG image file without operating export function on a real device.

This tool is under development and may change.

Installation

$ pip install supernotelib

Usage

To convert first page of your note into PNG image:

$ supernote-tool convert your.note output.png

To convert all pages:

$ supernote-tool convert -a your.note output.png

If you want to specify page number to convert:

$ supernote-tool convert -n 3 your.note output.png

You can colorize a note by specifing alternative color codes in order of black, darkgray, gray and white. Note that use #fefefe for white because #ffffff is used for transparent.

To convert black into red:

$ supernote-tool convert -c "#ff0000,#9d9d9d,#c9c9c9,#fefefe" your.note output.png

To convert into SVG file format:

$ supernote-tool convert -t svg your.note output.svg

To convert all pages into PDF file format:

$ supernote-tool convert -t pdf -a your.note output.pdf

You can also convert your handwriting to vector format and save it as PDF with --pdf-type vector option. Note that converting to a vector takes time.

$ supernote-tool convert -t pdf --pdf-type vector -a your.note output.pdf

To extract text from a real-time recognition note introduced from Chauvet2.7.21:

$ supernote-tool convert -t txt -a your.note output.txt

You can specify a page separator string for text conversion:

$ supernote-tool convert -t txt -a --text-page-separator='----' your.note output.txt

You can also specify number of cpu threads used using --workers or -j (speeds the conversion up a little):

$ supernote-tool convert -t pdf -a -j 15 your.note finmat2.pdf

The default setting uses up to 8 threads.

For developers, dump note metadata as JSON format:

$ supernote-tool analyze your.note
