Hi Pedro,<div>I'm using the composer + Atlas plugin to automate the creation of map series. These weeks the Atlas is undergoing a refactoring and the porting to C++, with more features then the current Python version. It sould come out during next one/two months.</div>

</div>Here is a nice code sample of creating a complex map using QGIS 1.8 api.<br>
<br>
<a href="https://github.com/AIFDR/inasafe/blob/master/safe_qgis/map.py" target="_blank">https://github.com/AIFDR/inasafe/blob/master/safe_qgis/map.py</a><br>
<br>
Also look at the source of the Atlas plugin. Note that in master<br>
things get considerably easier for creating a map in python since you<br>
can use a lot more templating etc. There are some unit tests which<br>
should provide a nice reference guide:<br>

<br>
It is better to write coding related questions to the dev list in my<br>
opinion. It would alse be good if you mentioned what OS and QGIS<br>
versions you are using when you write such emails so that we can give<br>
you platform specific advice. It looks very much like the Qt4 python<br>
modules are not in your path or are not installed.<br>
