Following today's conversation with Cedric on IRC, we will work on a PoC working on a client plugin that will be able to annotate on predefined background image.

Cedric has suggested the GTK drawingarea methods[1]

My idea is to have, per module, a set of pre-defined bitmaps (binary fields) (campimetry, odontogram, forensics, ... ) that we can reference from the client, and have the plugin the ability to annotate and, in some cases, map the area to a meaningful value.

Best,
