Hi Herbie and all,

to be more specific, have a look at Figure 1 from this (public
accessible) paper:

http://www.iop.org/EJ/article/0295-5075/67/5/800/epl8338.html

In Fig. 1/D a color map was applied to a pattern depending on the
rotation of that pattern.

In our case we are not (yet) dealing with a hexagonal 'pattern',
rather lamellar one, e.g. \\, =, //, ||.
Since I am not into AFM/SEM devices and software, I don't know what
software does the job, but would be great to know about it.
If you have any hint for writing such a plugin from scratch and got
any reference, would be great too.

Cheers,
Ludwig
