I don’t know if this has been attempted yet, but here’s a very quick WIP hack together of a small plugin that will allow you to draw a reply in a canvas. I got jealous of google hangouts so I wanted to hack something similar into discourse.
It’s not yet functioning, so I’m throwing it under broken-plugins (it also has pretty primative drawing methods, and starts with some test data already filled in the canvas). I stole a lot of modal view and such from the replygif plugin. Credit where credit’s due.
The broken part is – I’m not quite sure how to shove the base-64 png data across the wire as a file upload just yet (it just prints the data in the console and the compose window for now). Any pointers or suggestions to actually perform an upload would be great!
