Of course Matthias is right if you want to interface with a plugin<br>
instance running inside QGIS. That's why I said you could bind only<br>
the inner logic of the Georeferencer to use it "outside" the plugin<br>
instance. In case you need to control, or get work done from, the<br>
Georeferencer plugin itself you have to do what Matthias is doing in<br>
its commit.<br>

The python modules gui and core are exported and the "iface"<br>
variable (QgisInterface) knows about their presence. But<br>
QgisInterface should not have any dependencies on plugin code,<br>
therefore it's harder to access this code.<br>
It may not be hard if you only make use of code which you use in a<br>
standalone library way (maybe that would already be enough for<br>
your case). If you want to get access to a running plugin instance<br>
this is a different story. You can have a look at the code in [1]<br>
for an example of how this might be accomplished. Although the<br>
code seems not to be working, I've got to check what's still<br>
missing there, but in principle the ideas in commit [1] should work.<br>

<br>
It will not be so easy to just write wrappers because the<br>
code is not<br>
exported to the gui or core libraries/sip modules.<br>
I have written code that makes it possible to generate python<br>
bindings for (C++) plugins and I'm considering creating a<br>
pull-request for it.<br>

It depends on what parts of the Georeferencer you<br>
need. If you don't<br>
need the GUI but only the math, you could consider<br>
writing a SIP<br>
wrapper around QgsGeorefTransformInterface<br>

Hello Giovanni,<br>
thanks for your answer. Do you think it is<br>
easier to write<br>
the Plugin for the historical border<br>
extraction in c++<br>
instead of python, cause of the binding<br>
implementation?<br>
<br>

Hi Felix,<br>
I fear you will have to write your own<br>
bindings if you<br>
want to leavarage the Georeferencer plugin<br>
code. It's a<br>
plugin, so it's functionality isn't<br>
exposed through QGIS<br>
API.<br>
