[Qgis-developer] Map production using Python

Hi guys,
I have a few questions that I'd like to ask here.
1st - I'm trying to write a code that I can run from a python shell
outside QGIS, but I'm not finding the path where I should be importing qgis
from.
2nd - I have to print a series of hundreds of maps and I was
planning into using the a map composer, but in the map I get, my layer
occupy a small part of the whole composer. I have this problem when I'm
working manually too, but then I can correct it. How can I set it right so
my layer take the whole canvas?
I'm using the following software:
- Windows 7 64bits
- QGIS 1.8
Python 2.73
Thanks,
Pedro

physical layer that is loaded in QGIS, even in modeler, it works well.
However, when using Select with intermediate layers within modeler, it says
that the project has no active layer to select from (image attached).

I could do this with jenkins....maybe remind me at the HF if I dont get to
it before then.

glad you raised this question. The common users really misses a tool to
allow easily fix geometries in QGIS, and the feedback is that when is needed
they usually use other GIS software (for example many of the tools in the
"vector" menu do not return the expected results if the geometries are not
valid).
Any improvement in this field would be very welcome.
cheers

Dear QGis developper Team,
QgsFillSymbolLayerV2 descendants, but also QgsLineSymbolLayerV2 and
QgsMarkerSymbolLayerV2 descendants are missing from sip.
Working with styles to a deep level it is impossible without such
exportation.
Is this by design or can I add all the missing stuff in sip files?
Regards
Massimo
