If you're anything like me, you're a huge nerd engineering major who enjoys
working out problems both on whiteboards and digitally. You might also
have six million photos of your whiteboard work trapped on your phone
or in your Google Drive with no good way to easily group them in with
your other notes.
This uses autotrace to translate whiteboard markings into splines. Those splines are then passed directly to the Xournal++ API and rasterized, before being placed onto the working layer.
Debian:
Compile and install autotrace.
We're going to be using a fork of autotrace that includes a few fixes.
Upstream is currently broken (and likely to remain that way

Run make lua-plugin, it will compile inkpath and place inkpath.so in the ImageTranscription directory. Copy that directory to your Xournalpp plugins folder, and Inkpath will be installed. You can then use it from the 'Plugins' menu.
You can also run make to compile a CLI utilility that you can pass a source image and an output file path. This is useful for testing, or just starting a document. It will take that Bezier curve data and transcribe it to xouranalpp file syntax.
